BGP Routing Problem using Route-map

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.

BGP Routing Problem using Route-map

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....

BGP Routing Problem using Route-map

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 ?
