Cisco Switching/Routing :: Static Routing With C2960G Switch
May 28, 2013
Two Cisco C2960G Switches connected with each other using an EtherChannel Trunk Ports.IOS Image has been upgraded to c2960-lanbasek9-mz. 122- 58.SE2.bin.The global command "sdm prefer lanbase-routing" has been executed to set the default template to "lanbase-routing".The global command "ip routing" has been executed to enable the ip routing.An IP route has been configured in each switch to point to each other for the static routing purpose (Please see the 2 attached configuration files) The hosts in VLAN 111 and VLAN 110 are not able to see each other even the ip static routes have been configured.May be I have misconfigured some settings but not sure what's the actual problem.

I have couple C2960G and C3750. Is there any way to filter (on ingress port) type of traffic? I would like to allow IP only, and discard (i.e.) IPX, or other garbage, that any device can produce.I have tried to find something about this, but only thing I have found is feature : protocol filter, which doesn't seems to be working on my hardware.

i wonder if i can make a backup static route for an existing link over wan using the below diagram
the Core Switch type is 3750 in both sides i`m using only static routing for all destination like
Core1:
ip route 192.168.8.0 255.255.255.0 172.10.10.30
Core2:
ip route 172.17.200.0 255.255.255.0 192.168.100.105
requirements is to track the reachibility for the core ip address from both sides & change the routing automatically to the backup tunnel line

I have a stack of 2 x 3750X switches these are running 12.2(55)SE5. I needed to add some static IP routes and found that the ‘ip routing’ command is not supported. I came across a document that stated “On switches running the LAN base feature, static routing on VLANs is supported only with Cisco IOS Release 12.2(58)SE and later.” So I have upgraded to 12.2(58)SE2, but ‘ip routing’ is still not a valid command.
The release notes state:“On the Cisco Catalyst 3560-X and 3750-X Series, it adds support for 16 static IPv4 routes in the LAN Base image.”
I have read other posts that talk about running the ‘sdm prefer routing’ command which I have done, but I am still unable to add any routes or run the ‘ip routing’ command.

I have routing enabled, can build a static route, and go back and see it (sh ip route), but I don't know how to get the route right. I have one host (Host A) on Vlan 20 w/192.168.20.2/24 dg 192.168.20.11 (the vlan ip) and (Host B) on Vlan 30 w/192.168.30.2/24 dg 192.168.30.11 (the vlan ip). I can't ping them from any host man. I can ping the Vlans but not the host.

The last few days I've been exploring options in getting rid of some old routers accross a wan connections. I have a cat 3560 to play with and I thought I would try and use the no switchport command test out routing with switch. I've got some type of route issue and I tried a few things which I thought would fix the issue but had no effect. I'll post the config and a few commands so you can see what the basic setup is.
Here we can see in the arp that it knows about both 10.7.1.2 (PC unable to ping 10.3.3.254) as well as 10.3.3.254 (ASA).I tried adding in a ip route of 10.7.0.0 255.255.0.0 10.3.3.110 as well as 10.3.3.254. Neither produced the results I wanted allowing 10.7.1.2 (PC) to ping the ASA (10.3.3.254). [code]

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]

I have the task of replicating the router config on a 3825 router on a 3750 switch. Reason is we are taking out the router and replacing it with the switch to make use of the router for other functions.
Below is main part of the router config:
!
ip source-route
ip cef
!
!
multilink bundle-name authenticated
!
license udi pid CISCO3825 sn FCZxxxxxxx
!
vlan internal allocation policy ascending
[code].....
The 3750 switch I have runs C3750E-UNIVERSALK9-M, Version 12.2(55)SE3 on a LAN BASE license.
The first thing I have done is to order for a license upgrade to IP BASE which would give the support for OSPF routing.I do not see much of an issue with the Interface configs, however, I am not too sure about replicating the routing config on the switch.
My question is can I run the commands as shown for the OSPF routing on the switch? If not, can I get suggestions on how best to set this up on the switch?

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.
Switch Config
interface gi2
description connection-to-data-vlan

interface gi3

I have an environment of 3 X 3560G of which I have 1st switch-CORE(f0/10) connecting to the VPN router(CE) interface-f0/0. Remaining 2 Cisco 3560's(Access) are connected to Gi0/1 and Gi0/2 on the 1st switch-CORE via gi0/1 . On all three switches I have created multiple VLANs and assigned ports to these VLAN. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. Now the issue is how I am going to have all these VLANs routed through single interface on the routeri-e f0/0, as all these subnets will communicating to remote site over VPN. What should be default gateway on the 2 Access switches and the CORE switch, also what static route should be on router to reach all subnets(VLANs) created on these 3 switches.
I have read inter-VLAN routing i-e creating sub interfaces on router but dont want to proceed with that and looking for any other way to have my VLANs talk on all three switches and then are accessible to remote site ove VPN?

I'm running into what seems a basic ip routing config problem with a Catalyst 3750 (IP Base) switch. I have several VLANS configured on the switch with IP routing enabled, and the switch is connected to the inside interace of a new ASA 5520 as follows:
ASA5520 IP (Default gateway): 192.168.1.1Switchport Gi1/0/1 is configured as a routed port, IP address 192.168.1.3 255.255.255.0Example VLAN is VLAN 100, IP address 192.168.100.1 255.255.252.0 From the switch CLI, I can ping all VLAN addresses, as well as the ASA5520, and the client laptop I'm testing with from VLAN 100.
From the client laptop on VLAN 100, I can ping all switch interface and VLAN addresses (inter-VLAN routing is working), including 192.168.1.3, but I CANNOT ping the default gateway at 192.168.1.1.
Here is the relevant configuration information on the 3750:
!
no aaa new-model
switch 1 provision ws-c3750x-24
system mtu routing 1500

I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.

You can set the ME3400 switch set to the Routing SDM template such that it support PBR. That is done in the ASICs, right? Because if it is done in software the switch could quickly become overwhelmed.

I'm having some problems setting up vlans to talk to each other on a 3550-12T switch. Its quite a simple setup I have, but I need to split my network up.
Currently I have a network of 192.168.25.0 255.255.255.0 I want to create a new vlan network of 192.168.30.0 255.255.255.0 So I have configured my vlan1 (default vlan) to have an ip of 192.168.25.250 for getting to the management page
I have created a vlan2 of 192.168.30.1 255.255.255.0 ?I have a port 10 linked to one of my 3560G's?In port 9 which is on vlan2 I have my pc plugged in with a static ip of 192.168.30.50 from the router I can ping any device on 192.168.25.x.
I can not ping 192.168.30.1 (which is my vlan2) nor can i ping the PC.
I have enabled ip routing But I dont have a default route, this is becase we don't have a router on the network.

I have a Cisco 1841 router at home with version 12.4(13r)T advanced ip services. The setup is extremely simple:
1) PPPOE dialer to my service provider over ADSL
2) Nat overload on the dialer interface.
3) 2 V LAN s one for home network (wired) and one for wireless both v LAN's are connected through interface v LAN s respectively.
My problem is when I configure static NAT to map RDP or any other protocol to inside hosts this does n`t work.
"
ip nat source static tcp 192.168.20.3 2222 interface Dialer1 2222
ip nat source static tcp 192.168.20.3 3389 xx.xx.xx.xx 3389 extendable
ip nat inside source list 20 interface Dialer1 overload
"
When I open wire shark and sniff the traffic on home computer which is the one I`m trying to reach I can't see any traffic. And While performing Nat debugging I am also not able to see traffic going to that port (for example 3389).

I just did configuration on Cisco 892F router. Everything works fine, but static nat is not working. I create static nat on tcp port 80 (http). I don't know where is the problem. All nats working fine except static nat. Even though internet connection is ok in my lan.
i cannot access my router from the internet.

I guess i am just getting old and forgot how this works, or i have an IOS load with an undocumented feature in it.A customer of ours wishes to have their exchange server appear to the outside world on a seperate IP address as their public pool address is.in the past this has not been an issue, however in the current configuration we are unable to get the source address to appear per the NAT statement it always sources on the overloaded IP. below is the relevant NAT config, am i missing something, or have i hit a IOS feature? [code] There is a 45% chance i have forgotten everything i learned on the NOC desk and a 50% chance that it is somethine really stupid and 5% IOS is broken
