i have in a sw (3550-12T) defined 2 trunks on ports 0/2 and 0/3, with 2 routers (3725). I have also a PC on the sw in 0/5. all the 3 interfaces (pc + routers) are into the same network 192.168.200.0/24 and all in the same vlan 4. i can ping from the pc to the 2 routers, and from the routers to the pc, but i can't ping from one router to the other.
The problem, i think, is at the sw, he don't switch between the two trunk ports. It's a config problem, or it's not possible.
What you want to do is possible. Most likely there is a mistake in the config somewhere. I could ask you a lot of questions and not still find the answer. The easiest would it be when you upload the config of the switch and the relevant part of the routerconfigs.
The fact that you use one router instead of two changes the matter a bit.
When pinging from the router you need to know what is used as the source-adress for the ping. Suppose the PC =2, not 5.
For the rest the config is not extensive, but it should work. There is just one thing that remains a puzzle: the ip vrf command on int fa0/1:2. You did not list the related lines. Why did you put it in? As the rest seems more or less ok, this is likely to be the cause of your troubles. Try to remove it and see if it works.
About the source address: When you have two equal paths to a destination, which path does the router use? In your case, both fast eth. are the equal paths. So when pinging from the router to any network host, what is the IP-source in the ping request?
To verify a path, you normally use an extended ping and then specify the source adress.
aha, i got your point but not i my case, i have 2 router, one real and one virtual (vr1) so when i do "ping 192.168.200.1" i have the source 192.168.200.5, and when i do "ping vrf vr1 192.168.200.5" i have source 192.168.200.1
and how do i specify the source address in the "ping" from the router???
