Routing

Hello,

I have three route reflector configured in the core where, R3(RR) is directly connected and R5(RR) is connected to R3. I'm trying to do ping from R5 to T1 or T2 but i can't ping there. Please advise what i'm doing wrong here.

Please find attached config file for R3, R5, T1 and T2 Router.

Try to ping with source address of lo0 interface

 ping source XXX 130.130.0.1

P.S. also you can configure default-address-selection to use address from lo0 interface by default

Thanks for the quick reply.

I can't ping using source address as well.

root@R5# run ping source 10.0.3.5 130.130.0.1

Hi, 

I would suggest checking on T1 & T2 for return routes to R5.

Also, doesn't seem to be having a route for 120.120.0.1 on R5.

Cheers,

Ashvin

Thanks Ashvin!!. I really appriciate your help.

Policy wasn't configured correctly on T1 and T2, That's why i wasn't able to traceroute to T1 and T2 from R5. Corrected the policy and i can see route for 120.120/16 and 130.130/16 from R5.
