Cisco Switching/Routing :: SG300 Inter Vlan Default Route
Sep 23, 2012
I just got my Cisco SG300 28, but I have some problems getting the routing to work. I get the vlans to get to the router, with the default route. But not getting them to talk with each other. I can ping the IPs from the cisco, but I am not getting traffic to go from vlan 1 to vlan 2. When I try to google, it say that it should do it automatically, and I found no setting for it. It looks like it not creating any route for the interfaces.
I recently set up a small photography business and am trying to get a Cisco 877 and Cisco SG300-10 switch to talk to each other.
What I want is for the Cisco 877 to handle the internet and the SG300-10 to handle the local network,
I have set up 2 vlans in trunk mode on the switch and want vlan2 to manage local traffic and vlan3 to handle the internet.
I have got the 877 connecting to the internet what I dont have, traffic going to vlan2 on the switch from the 877
Look at the running configs for the switch and the router and tell me how to get the vlan on the router to pass traffic to the switch. In a nutshell I am inserting the internet into the switch but am not sure how to progress. I have the c870-advipservicesk9 image file on the router.
We have recently purchased a Cisco SG300 and have been configuring it. [code] The VLANs have ACLs set up to prevent any communication between the Holly and Tempo VLANs (and their associated WAN VLANs).Each VLAN has a WAN available for it's use, which connects to external networks (including the Internet).In order to facilitate this, we have set up all the necessary ACLs and routes and confirmed that this all works.However, the problem comes when we assign the static routes that specify the default gateways.We add the two static routes below:
-0.0.0.0 next hop 10.10.200.254 metric 1 -0.0.0.0 next hop 192.168.200.254 metric 1
In this case, only one of the VLANs has WAN access. It is either Holly or Tempo (it can be either if the order the static route is added is changed).What we need is to force Holly to use Holly WAN and Tempo to use Tempo WAN, but we cannot see a way of doing this.Effectively, we want the following static routes: [code]
I have a connection on IP 192.168.1.21, Subnet 255.255.255.0 - this is on the default VLAN1 on the switch. I need to route this to IP 10.0.3.101, Subnet 255.255.252.0 - which is set up on VLAN2 on the switch. I have set the switch to Layer 3 via console.
how I setup this route? I am use the Browser based interface.
configure my new SG300-28P. When I have started the switch, I have specified a new password and enabled telnet in order to setup the switch in Layer 3 mode.
After a restart, the switch took its IP address from a DHCP server. When I try to set a static IP address (192.168.2.1), I receive the following error message: Duplicated IP interface on the same subnet.
The IP address 192.168.2.1 is not used by any device within the network. For information, the message doesn't appear when the switch is in Layer 2 mode.
why I can't change the IP address of default vlan in Layer 3 mode ? All I can do is set the IP address to static or dynamic.
For test purpose, I have added 2 vlans. But I wasn't able to route traffic between vlan. how to configure the switch to route traffic between vlan?
find below details informations about my VLANs.

My organization wishes to host a LAN gaming event. The setup I have in mind involves a 24-port switch for connecting all the player computers and having that switch connected to a smaller "core" switch which has the the game server and router connected to it. I'd like to know if I can set things up as follows...
SG200-26 with ports 1-24 on seperate VLANs so they cannot talk to eachother. I'd then like ports 25 and 26 to be an aggregated (for bandwidth and redundancy) trunk port to carry all 24 VLANs plus an additional management VLAN (ex. VLAN 100) that will be used for accessing the switch. I'd like those aggregated trunk ports to connect to an SG300-10 "core" switch which will be connected to the game server and to a router for internet access.
I'd like the ability to have two network connections from the game server to the switch, one on the management VLAN and one on a different VLAN (ex. VLAN 50) that will be accessed by the players (ports 1-24 on the SG200-26). The core switch needs the ability to perform restricted inter-VLAN routing, in that it doesn't allow VLANs 1-24 to talk to eachother but they can talk to the server's VLAN but only through specific service ports (ex. port 12345, 12346). Is this possible?
Furthermore how would I configure the SG300-10 to allow VLANs 1-24 to talk to VLAN 50, but not themselves or VLAN 100. As well, I'll probably have the router on it's own VLAN (ex. VLAN 60) and allow VLANs 1-24 to access it but only through HTTP port 80 for web access.
we have an SG300 latest 1.3 firmware, we have it acting as our DHCP server, we have a 10.10.1.x range, 10.10.3.x range, and 192.168.24.x range, they are all on seperate VLANs and all can talk to each other which is what we want. However we have someone who wants to use the 192.168.1.x range to add IP cameras to our network using there own switch. I figured I'd just setup our server to do DHCP etc and it would communicate with the 10.10.1.x range of IP addresses no problem. It turns out the SG300s can't do DHCP for that range, so if he has all static address on the 192.168.1.x range how can i setup inter VLAN communication so we can talk to that range?
I've been given the task to clean-up our network config, and have walked into a disaster zone.We have a 4510R on site with everyone using the default VLAN, VLAN 1.I have created 4 new VLANS, VLAN100, VLAN150, VLAN200, VLAN250 I have assigned interface addresses to each VLAN and configured Inter VLAN routing.I can route to and from each new vlan with no problem, i.e VLAN250>VLAN100 VlAN100>VLAN200 etc but I can't route to VLAN 1(Default VLAN) from any of them, I can ping the interface on VLAN 1 from any VLAN , but any hosts are unreachable. On the flip side , from VLAN 1 I can route to all of the VLANS.
Probably an easy fix but something's weird in my config. I am setting up a new network, so this is not production, Routed environment, down to the access layer using 3560-x l3 switches.
vlan 10: data vlan 20: wifi vlan 30: wifi guests vlan 40: voip
My objective is to allow all traffic OUTBOUND to certain subnets (10.10.0.0/24, 10.10.100.0/24, 10.10.110.0/24 10.10.120.0/24) and block any other 10.0.0.0/8 networks. By doing it this way, after blocking all other internal traffic, I allow everything else to ensure internet traffic can go out.

I have a DC topology based on 2 layers, access and aggregation, based on 2 pairs of N5548Ps, both without L3 Daugher Cards. My intent is to use the aggregation N5K pair as L3 inter VLAN layer, so I configured all the VLAN default GWs there. The 2 layers are interconnected via vPC, in a double-sided vPC topology for some N2Ks and some vSwitches. The point is that, despite connecitivity is working fairly ok, for some applications, like file transfer via either FTP or HTTP, between hosts in different VLANs, the performance is too poor. The file transfer starts ok, but after a while it becomes lower and lower. ICMP is working, but I can see some strange random behaviour, like having some packets taking more that 20 ms (sometimes 40 or more), whilst average is 2 ms.
I read through some articles saying that until you don´t have the L3 license (the one coming with L3 Daughter Cards) you can expect some weird behaviour on L3 level. Is that true?. What can I do apart of purchasing L3 Daughter Cards?. Can I enable L3 Basic license at the moment (I don´t need dynamic routing for now).
Here some excerpts of what I´m saying:

I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet. I think it has to do with the routes. [code]
We have two Cisco 5505 firewalls connecting to two ISP's . The two internal LAN's on the firewalls are 192.168.184.0/24 & 192.168.186.0/24. We also have a Cisco C3560x layer3 switch with vlan interfaces 184.3 & 186.3. We have two DGS-3100 Dlink layer 2 switches connecting our users to the Layer 3. Ip routing is enabled for intervlan communication & I can reach the Switch interfaces & firewall gateways from machines on both on the vlans.We have pbr enabled on the 3560 & users only on the .186 network can get to the internet. The switch is running the ipservices license & the sdm template is "desktop routing" .
Users on the .184 cannot access the internet but we can ping the layer3 interface & the firewall gateway. [code]
In 3750 switch,I have configured intervlan routing.I have three vlans Vlan 10,vlan 20,Vlan 30 and I have assigned IP address for that Vlan.In vlan 10,I have connected one systen gigabitethernet 0/1 interface.From my system I am able to ping vlan 10 ip address but I can't able to ping other vlan ip address (vlan 20,vlan 30).Is it possible to up the protocol for all that time.
I am working for a large campus network. The network has more than 70 VLANS in a Layer 3 Switch(Catalyst 4503). Customer wants to stop intervlan routing between all vlans except 2 vlans. How will i do that? I have also a Firewall (ASA 5520) & a Router (2811) in up of the switch. Besides this, I have run HSRP in Layer 3 Switches for redundancy.how will i stop intervlan routing between VLANS except 2, with ACL or any other process has?
I'm looking to restrict Inter-VLAN routing through L3 switch (cisco 6500) and wanted to know best possible way to do it. I used VACL and achieved success to some extent, but my config is making clients take up to 5-6 mins to authenticate IP address from the DNS (bootps).My VACL config was as follows:
Subnet to restrict is 10.100.15.0 (VLAN 15) STEP 1: Created extended ACL to allow bootpc/bootps through DNS ip access-list extended EACL_DNS permit udp any eq bootps any permit udp any eq bootpc any
STEP 2: Created standard ACLs to allow only relevant subnet, server VLANs & some IPs from other subnets for printers/scanners etc.
ip access-list standard SACL_VLAN_15 permit 10.100.15.0 0.0.0.255 (the subnet I'm restricting) permit 10.100.50.0 0.0.0.255 (server VLANs) permit 10.100.25.45 0.0.0.0 (printer in another VLAN which has to have access in VLAN 15)
STEP 3: Created VLAN access list
vlan access-map VACL_15 10 match ip address EACL_DNS action forward vlan access-map VACL_15 20 match ip address SACL_15 action forward
STEP 4: Applying VLAN Access list on VLAN 15 vlan filter VACL_15 vlan-list 15 Though the above works, below is noted:
1. I'm still able to PING 10.100.15.2 (the switch virtual interface) from outside the subnet, which I don't intend to do so. Howeve all cients in the subnet have no connectivity from outside the VLAN 15.
2. As mentioned its taking quiet some time to negotiate with the DNS server at system boot time.
you find attached my network architecture with 2 Nexus 7010 on core layer and 2 Nexus 5020 on distribution layer, each one with 1 N2148T fabric extender switch. PC-A1 and PC-A2 are connected to one N2148T, PC-B1 is connected to the other N2148T. Nexus-7000-1 is HSRP Active for all VLANs, Nexus-7000-2 is HSRP standby. PC-A1 and PC-A2 are connected to VLAN A, PC-B1 is connected to VLAN B. PC-A1 and PC-A2 have the same default gateway correspondent to IP HSRP on VLAN A. It happens that PC-A1 is able to ping PC-B1 while PC-A2 is unable to ping PC-B1. If I issue a traceroute from PC-A2 I see Nexus-7000-2’s physical IP address as the first hop even if Nexus-7000-2 is HSRP standby. After the first hop the traceroute is lost. If I shutdown Port-channel 20 on Nexus-5000-2, PC-A2 starts to ping PC-B1.I can’t understand what’s wrong in this architecture.
I have just bought myself a Cisco 2821 ISR.At present in my home I have a Cisco 2621XM. Fast Ethernet 0/0 is connected to a 3524XL as a trunk to provide my LAN with inter-vlan routing. it works great. Fast Ethernet 0/1 is connected to my ISP's cable modem and uses the command "Ip address dhcp" to get an IP and all other info from my ISP.FA 0/1 is Ip nat outside and the FA 0/0 and all sub interface like 0/0.1 .24 .168 etc all ip nat inside.I get intervlan routing and access to the internet via this router.I have this 2821 to replace the 2621XM as I plan to run CME on it and want gigabit routing on my vlans as at the moment on the 2621 routing between vlans it at half duplex or seems to be.I have configured the 2821 to ip nat outside on gig 0/0 and ip nat inside on gig 0/1 and all of the sub interfaces (same setup as my 2621 but with gig ethernet)I have no access to the internet at all but I can ping www.google.co.uk and other domain names from the terminal session when I am connected to the 2821 via the console or telnet/SSH. the gig 0/0 has an IP assigned from my ISP too but no other nodes on the network can ping outside.Am I missing something here? the version of IOS is V 15.
My access list goes someting like
access-list 1 permit 10.0.0.0 0.255.255.255 access-list 1 permit 192.168.1.0 0.0.0.255 access-list 100 permit ip 10.0.0.0 0.255.255.255 any access-list 100 permit ip 192.168.1.0 0.0.0.255 any and so on
I have a SG 300-28 switch with the latest firmware installed running in Layer 3 mode.
I configured this router with 4 VLAN's where VLAN 1 is connected to the network router. All VLAN's call all communitcate with one another. How do I go about configuring VLAN's so that they can only communicate with the router and the internet and not each other?
I have one cisco 3750G-48 switch, one cisco 3560G-PS switch, Cisco UC520, cisco 2851 and cisco wireless access point.i have setup up intervlan routing between the two cisco switches and the uc520 with a total of four VLANS, the problem i'm having is with the 2851 router, I have created a trunk between the 3750 switch and the 2851 router. should I create subinterfaces on the 2851 router for the four vlans by doing gigabieethernet 0/0.1, 0/0.100 and so on or should I create BVI subinterfaces.
reason I ask is I created four vlans on the vtp server switch which is the 3750 and I connected the uc520 to the 3750 switch via a trunk interface and set up vtp client on the uc520, after I setup p the vtp on the uc520 the vlans were automatically created on the uc520 with each vlan having its own BVI interface.
So I am not sure how to configure the 2851 router to interact with the four vlans. also the 2851 router have two hwic 1adsl wics installed which will have two adsl connections coming in.how to set up the 2851.
I am looking for a reasonable switch but it has do do inter-VLAN Routing. I know I could go with a 3560/3750 with IP Services but I am also thinking the 2960S with IP Base IOS might do?
I have looked up the IP Base IOS and it does list IP Routing but how to actually configure inter-VLAN Routing on a 2960S with IP Base?
but on interface gi 1/0/1 i want to have data from vlan 10 tagged as VLAN 20. At this time i have solved this issue very primitively
I have set up gi 1/0/2 as int mode acces, acces vlan 20 and i have connected gi 1/0/2 with gi 1/0/3 with eth cable. int gi 1/0/3 is switchpor mode acces, switchport acces vlan 10
I'm having an issue routing between vlans. I have vlan 1, and 2. I want to ping something on vlan 2, from vlan 1. I cannot ping from a computer on vlan 1 to a computer on vlan 2. I can ping each computer from the ASA 5505. I get an error on the ASA when I try to ping from the computers. The error is Failed to locate egress interface for UDP from voice:192.168.0.199/137 to 192.168.1.200/137. I can't understand why it even mentions IP 192.168. 1.200/ 137... I reset the unit configuring it from scratch and still no go. I have no given a static route to the out yet.. I need to get inter-vlan routing working first. [code]
My architecture is the same as show on the link with some difference.I use the router 1841 for inetrnet connexion instead of 7200VXR, this router 1841 is connected on the catalyst 3750 port G1/0/1.I use catalyst 2960 instead of catalyst 2950 or 2948.I use ASA 5510 for conexion on remote branche(I have 5 remote site), This ASA is connected on the catalyst 3750 port G1/0/37
Result of the test:
-I can ping devices in the same Vlans -I can ping devices in different VLANs -I can ping all device from the catalyst 3750
I cannot ping the router 1841 or ASA 5510 from the any devices (computer)The gateway of each computer is the correpondant VLAN IP address configured on the catalyst 3750.Why I cannot ping the router 1841 or ASA 5510 from the any devices (computer)
I have a MPLS cloud in our data center. I want one network coming into our core router to have a different default route than the other networks coming in. I'm getting hits on the acl but the route isn't applied and goes to the default route that is configured in the router. I have other PBR for setting local-preferences and as-paths and they are working fine.
The router is a 7206 Version 12.4(11)T3

I have a Cisco 2960 ( WS-C2960-8TC-S) running 12.2(46)SE C2960-LANLITEK9-M image.I would like to set an ip route 0.0.0.0 0.0.0.0 87.101.156.97 but the current image does not allow.Will ip default-gateway 87.101.156.97 work or do I need ip routing ?The ISP has provided a /30 address and we are using an additional /29 for our network devices. I dont think this image can be upgraded. I need to forward routes directly out to ISP. [code]
I'm working on a little OSPF setup in my lab and having a problem pinging out to the internet.I have a setup with (3) 3550's running ip routing. I'm configuring OSPF but I can't ping the internet from any L3 switch except the switch with the actual uplink to the internet.[code] From SW2 and SW3, I can ping SW1 on all IPs (192.168.1.90, 10.10.10.1, 10.10.10.5) but I can't ping 192.168.1.1 which is my gateway to the internet.
I have a 3750 at a branch running EIGRP connected to two routers that both have configured:
access-list 1 deny 0.0.0.0 access-list 1 permit any access-list 2 permit 0.0.0.0 access-list 2 deny any
router eigrp 1distribute-list 1 out FastEthernet0/0distribute-list 2 in FastEthernet0/0
Due to this recently applied config the switch become unreachable from the outside and cannot ping anything. Everything connected to it works fine. I was able to remote into it from a switch behind it and noticed that the 3750 has no default route in the routing table. I do see a default route in the eigrp topology table. How to make the switch learn a default route maintaining the existing configuration on the routers.
