Hello Everyone
I have an issue with BGP routing lab. I want to ping loopback 1 from R1 to loop 6 in R6 & vice versa , but i don’t want any other router into routing table except BGP peers & loopback1,6&7. All other config is working fine is working well. but in R2 under bgp process when I do redistribute ospf 1 route-map xyz it won’t pass the ping to the destination. I am putting my config file so you guys can find my error.

Hi Sarbjit,
Please include keyword subnet in OSPF redistributions and check if problem still persists...

Thanks for reply....no it is not working...i ping from R2 it is pinging... but when i ping it with source fa0/1 failed....

Hello Sarabjit,
Are you trying to ping from source f0/1 of R2? If yes, then it won't ping. The reason is, your access-list denies the network to be advertised into the eBGP.
Do you see the route for 1.1.1.1/32 on R4 ?
06-12-2012 10:12 AM
R4#sh ip route

Gateway of last resort is not set
