Hello all,
Been doing some research on this topic and wanted to make sure I am on the right track. I have a point to point fiber connection between two routers, each of those two routers have a Catalyst switch with a trunk port. Each switch has a vlan configured. There is a computer in that VLAN that needs to talk to the computer on the other switch. The VLAN are the same numbers but the switches are in different VTP domains.
Currently each router is configured as so:
PC1 ----- SW1 ------ R1------FIBER------R2------SW2------PC2
Router1
interface FastEthernet0/0
description LAN
ip address 192.168.1.1 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp

interface FastEthernet0/0.100
description VLAN100
encapsulation dot1Q 100
ip address 10.10.10.1 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
ip virtual-reassembly
interface FastEthernet0/1

IP on PC1 = 10.10.10.2
-----------------------------------------------------------------------------------------------------
Router 2
interface FastEthernet0/0

ip route 0.0.0.0 0.0.0.0 192.168.254.1
IP on PC2 = 10.10.11.2
Since the switches are separate VTP domains, I assume I need to use some sort of routing to get PC1 and PC2 talking. Is this as easy as putting the vlan100 interfaces on each router into the same bridge-group 1 and enabling bridge 1 protocol ieee?
Just as a side note, when I ping the virtual interfaces from the opposite routers and workstations I am getting replies, so the connectivity through the fiber looks good. If I do a traceroute from the PC, it hits my local router, the opposite subinterface and then just responds with * and never completes.
Thanks!
Solved! Go to Solution.
Christie,
It's actually easier than that. Run a routing protocol between the 2 routers and you'll be able to get to the other side with no issue. Or, if you don't want to do that, you can do it with static routing.

With static routing you're just refering to ip routes? That's what I wanted to do but it's not working
I have tried both the things. But its not working.
show ip route
its shows the static routing and direct connection but still its not working
Sure. On router 2 you'd put a route like:
Ip route 10.10.10.0 255.255.255 192.168.254.1
On router 1, you'd put:
Ip route 10.10.11.0 255.255.255.0 192.168.254.2
You should be able to ping between hosts. I'm doing this from my iPhone, so I hope I have your addressing correct since I can't see your original post from this window :)

I have tried exactly that with no luck
It's almost like when the packet gets to the other side it does not know where to go. I do not have an ip set on the actually VLAN100.
Can you ping 10.10.11.1 from the 10.10.10.2 host? If so, can you ping 10.10.10.1 from the 10.10.11.2 host?
Yes, they can ping both interfaces but not each other.
Christie,
Out of curiosity, are these the primary ip addresses on the workstation? Can you post "route print" from one of the workstations? Also, can you post, from Router 1, "trace 10.10.11.1".

The issue was a misconfiguration on a switch in the main location, the trunk port was not properly configured. There were multiple switches and I missed that one So the routes do work so I will mark that as correct. Thanks!
