imagine I want to make VLAN200 workstations communicate like the show in the attachment. What would be the default gateway to be configured in the workstation? If I configure 192.168.1.1 as the default gateway (R1 interface fa0/0) is this right?That could be possible because the switch should be configured with command "ip default-gateway 192.168.1.1"?
View 4 RepliesI have two ISPs. Each is on it's own subnet connected to the 6509 MSFC/Switch. FW1 is on 100.1.100.0/30 and FW2 is on 200.1.200.0/30 subnet. My goal is route all traffice going to the Internet from subnet 10.133.3.0/24 to FW1 and all other subnets across the organization to FW2. I am not sure if I need to use ACL / Static route combo, or just a static routes or ACLS?
View 5 Replies View RelatedWe have two catalyst 3560 switches running c3560-ipbasek9-mz.122-58.SE2.bin They are connected using etherchannel using gi 0/21 - 24 interfaces.
on 3560-1 switch, there isn't any ip-default gateway or ip route configured. It only have 1 interface vlan configured.
on 3560-2 switch, there is ip default gateway configured along with 1 interface vlan.
What i dont understand here is that, i can reach out to other subnets from 3560-1 switch in which the routing is not enabled?
This would probably sound like a stupid question but it took at least 2 hours of my time so far. I have a 3750 switch where a router and a server is connected. From the switch I can ping the router and server with no issue (directely connected). But from the server I am not able to ping the router. The router and the server are in the same subnet. The router is configured as the default router for the server. I am not able to ping the server from the router either. Here's the output of the ip route from the router. The server IP address is 10.1.200.21 and the router IP address is 10.10.200.1
10.0.0.0/8 is variably subnetted, 8 subnets, 3 masks
C 10.1.30.0/24 is directly connected, FastEthernet0/0.30
C 10.1.20.0/24 is directly connected, FastEthernet0/0.20

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]
View 5 Replies View RelatedI have a bit of a mystery on my hands. I had a whole campus of Cisco 3750's cache a new default gateway. Example
Cisco3750#sh ip redirects Default gateway is 10.10.10.1
Host Gateway Last Use Total Uses Interface172.16.0.5 10.10.101.179 0:00 185749 Vlan1172.16.0.76 10.10.101.179 0:01 47254 Vlan1192.168.0.154 10.10.101.179 0:00 183090 Vlan1
My question is what generates a IP Redirect packet or how does the switch know what to change the gateway to? As in my case the changed gateway was a dead IP address. So I am at lose how this happened. I this case the Host IP's are network management servers conducting polling.
I have a 3500 XL switch with the following default gate IP address that i need to clear from the switch but not quite shore how to remove it.
I've removed the customer original Ip for security reason as this is an open discussion forum and just replaced with 1.1.1.1

I have created two vlans, vlan 1 data and vlan 200 voice. the issue is that when an on one vlan i cannot ping the default gateway of the othe vlan from my PC. An using sge 2010p switches.

I'm trying to configure an IPSEC VPN + tunnel for multicast data. When the default gateway is set on the router (1841) it works fine but if I only set a route to the IPSEC peer via our gateway then the tunnel fails to come up. The end point is to a 3rd party. [code]
I found that if I add a static route for the tunnel destination via fa0/0, the public facing interface, the tunnel comes up..ip route 10.23.4.2 255. 255. 255. 255 FastEthernet0/0
and I can then ping the tunnel IP at the far end - 10.23.0.5.Why would that be? Is there a better way to do this without using a default route??
I have a design hurdle that I cannot seem to cross. I have two sites and I need the same VLAN to span both sites. I have accomplished this using L2TP but my issue is that I can no longer assign a gateway for this VLAN on the router. The 2 routers are 2821's and are connected with a dedicated fiber run.
Ant recommendation for how this could be accomplished? It would be great if I could have the same gateway at both sites by leveraging some sort of bridged interface (BVI so I've heard) but I am at a loss as to where I should start with this. Also, this is not the only VLAN that needs to traverse the link.
Recently we observed that newly installed WS-C3560CG-8PC access switches are able to communicate without a default route or default gateway.The 3650 switches are used as a layer2 access switch behind a layer3 distribution/core. They have only the management VLAN configured for IP with a single address.
The ARP table looks like there is an implicit proxy-ARP request sent for any IP address.
We definitely have no configuration whatsoever which would explain this.
Is this a new feature? We don't observe that with the older 2960-series...
Here is a brief trace of what's happening (debug arp):
host41#ping 1.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
Sep 20 14:44:06.706: IP ARP: sent req src 10.1.8.41 1833.9dc9.wxyz,
dst 1.1.1.1 0000.0000.0000 Vlan1
Sep 20 14:44:06.711: IP ARP: rcvd rep src 1.1.1.1 2c54.2dd3.wxyz, dst 10.1.8.41 Vlan1..
[code]....
The mac address if of course the mac address of the layer 3 interfaces of the distribution switch, no surprise here (proxy ARP is turned on by default).
Why is the 3560 sending out proxy arp requests without being told to? As far as I understood proxy ARP on Cisco IOS it only means it will reply to a proxy ARP request but will not send out proxy ARP requests by default.
Using Network Assistant in XP, plugged ethernet cable to first front port and keep getting "Failed to get Default Gateway. Check your security settings to make sure the current Java Virtual Machine is not prevented from running commands.", I have tried reducing secruity to nothing but I still get the same problem.
I also have an official cisco console cable and tried that, but Hyperterminal just does not pick it up when plugged in. I have left the IP dynamic, turned off all netowork adapters apart from ethernet, set the baud rate etc... correctly, still no joy.
We have a Cisco Catalyst 4506 running: "Cisco IOS Software, Catalyst 4000 L3 Switch Software (cat4000-I9K91S-M), Version 12.2(25)EWA14, RELEASE SOFTWARE (fc1)" I have configured the default gateway as: ip default-gateway X.Y.116.65, However, when I do, "show ip route", it only shows the 3 connected networks and states "Gateway of last resort is not set". The Command "ip classless" is not set. I read on some blogs that this might explain the issue. However, when I go into config mode (config t), I get the following output.
View 9 Replies View RelatedI have a 3560G and an ASA FW, for which I am trying to use PBR to append the next hop. The gateway is the switch VLAN address and the amended net hop is the same VLAN interface on the ASA. Trouble is, I can ping the FW from a client, but not the switch. If I remove the route map, I can ping both. Even more strange is this is the case for some VLANs, but not all!

I had setup a lan infrastructure with 5 3750 stack swithes. In these 3 of them are in one stack which is acting as access switch, 2 of them in another stack which is as core switch where all the SVI is configured. Now, when i tried to ping from our edge pc which is connected in access switch to default gaeway, which is configured in core switch, the ICMP is getting delayed . But when try to ping from the same edge pc to another user PC, it is getting less tahn 1 millisecond icmp replies.
why icmp is delaying to default gateway , but working with another edge to edge pcs without any delays?
We have two MPLS circuits managed by two different suppliers, one carries VOICE the other DATAWe are to decommision the VOICE MPLS and have increased the bandwith of the DATA MPLS to carry VoIP traffic too.
At both of our sites A & B ,devices connected to the LAN have a default gateway of the VOICE providers Cisco 2600 router , which then goes into the LAN switching. (see diagram)So what I am trying to achieve is toto simply replace these 2600 routers from the VOICE MPLS provider with our own so we dont have to change the default gateways at both sites.
Testing
Our Cisco 2600 routes are plugged into each LAN switching environment with two subinterfaces configured, one for voip and the other for dataThe problem is from the router and respective subinterfaces we can get to the other sites destination without any issue, but if for example a user is at site A with Ip address 10.16.11.12/16 they cant ping the VOIP subnet at site B 10.3.11.0/24. But If a ping is issue from the Site A test router then the 10.3.11.0/24 subnet is reachable but only on the 10.3.12.0/24 configured subinterface.So i guess what Im saying is 10.16.0.0/16 from the LAN needs to be able to get to 10.3.11.0/24Note at site A 10.16.0.0/16 & 10.3.12.0/24 can communicate no problem and at site B 10.207.0.0/16 & 10.3.11.0/24 can communicate no problem.We are using IP routing, should we be using route-maps?
We have a 6509 series of core switches and 3750 series of L2 switches, There is no default gateway or any static routes to any IP.VLAN 1 is made admin down and another vlan is used for all communication here in this environment
Attached is configuration for reference But still I am able to take telnet or SSH. I want to know how telnet or SSH or tacacs authentication happens without any static or default route.
i am facing a problem when the client vlan is commmunicating with the default gateway on the core 3750-x.
ios in 3750-x core is 3750e-universalk9-mz.150-2.SE.bin. But, client to client communication is happening without any dealy and icmp is less than 1 ms always.
When try to ping default gateway of client vlan, it is getting delayed (variable icmp delays). Is this an ios bug?
4500 switch is connected to 2960 switch.
4500 config
Vlan 10

It has ip helper configured that points to DHCP.From 4500 switch port - port x connects to 2960 port.Port x is configured as trunk between 4500 and 2960.

vlan 10
name data
All user ports are configured under vlan 10 and as access ports.Port x is trunk port connected frpm 2960 to 4500 switch allowing vlan 1 and 10 only.This switch has no default gateway configured.
We connected user PC on 2960 switchports and they were able to get the IP from DHCP server and were able to access the network? My question is how users on 2960 switch are able to access the network without ip default-gateway configured on 2960 switch?
We had a core switch (4503), distribution switches and access in our network and consists of many vlans. Almost all vlans uses DHCP Pools. But for few vlans DHCP is not yet configured. Recently one of the rogue user in vlan 1 gave the corresponding interface vlan ip of core switch (gateway) as his ip and caused a prolonged network outage for the vlan. Any way we are going to seggregate vlan 1 into different vlans, but before that we need a temporary plan to block such kinds of attack.What are the possible ways we can avoid the network outage problem even if a user gave the gateway ip to the machine?

View 3 Replies View RelatedI am trying to get rid of 2 old 2651xm's and 2 2950's from my CCNA days and want to get into the ASA realm. Can I be able to use the ASA, not only as a security appliance / firewall, but also be able to write the access lists, etc, to be able to use this as my router to push packets to and from my internal LAN to the outside world? I guess I should have stated as this being the front end device to my network, just after my DSL Cable modem, that is..and being the only device. I am trying to have this as my main router /firewall solution and then I have an old Linksys router I will pipe off one of the L2 ports to have an AP for my wireless devices?

View 2 Replies View RelatedWe have a network consisting of a central site and a few remote offices. The sites are all connected via MPLS and also have VPNs over ADSL / internet connections as a backup. The remote offices have Cisco 837 routers for the ADSL connections which we can manage but the MPLS routers are managed by the service provider providing the MPLS connections. At the central site we have a Cisco 891 for the the MPLS connection (which we manage) and a Cisco ASA5505 for the backup VPNs.
In order to implement failover from MPLS to VPN in the event of any MPLS line going down I have tried to use ip sla monitors and tracked objects on the 891 as per Cisco's documentation. The problem that I am finding is that I can't set the number of ICMP echo failures required before the tracked route is dropped. Whenever the ip sla monitor fails to get a response the tracked route is dropped immediately. This is too sensitive as packets are occasionally dropped which results in the routes bouncing back and forth between MPLS and VPN too frequently (disconnecting users in the process).
I have tried different threshold types and values, tried configuring ip sla monitor reaction-triggers (although I don't understand what little documentation that I can find on this) and have even looked at event manager. I have been working on this for a few weeks now and am getting nowhere.
The Cisco ASA5505's implementation of ip sla monitor is much better in that it is possible to specify the number of packets but unfortunately we can't use the ASA as the default gateway for the LAN as the asymmetrical routing that occurs does not work with the firewall function of the ASA.
Any issue with ip sla monitor on IOS and managed to get it working?
