EIGRP - Scenario - Routes learned

[satishmothukri]

Hi All ,

As per attached diagram , EIGRP is configured between Wr01(router) to Sw01(switch) and Wr02 to SW02.

IBGP is configured between Wr01 to Wr02 (connected back to back) and trunk link is configured between Sw01 and Sw02.

EIGRP to BGP and vice versa is reditrubted on both the routers.

Question : If the interface of Sw01 goes down which is connecting Wr01 , How Switch 1 learns routes from Switch 2.Will the decives connected to Switch 1 able to reach (ping) remote location devices.

Sw01 and Sw01 (switches) are having L3 capability.

Any suggestions on this are appreciated.

Thanks ,

Hi

Does Wr01 run EIGRP with Wr02? If yes, Sw01 should learn all prefixes from Wr01 if connection to Sw02 goes down.

Hi,

If Wr01 is the primary and Wr02 is the backup, you will need "bgp redistribute-internal" on Wr02, as the routes from Wr01 will be preferred than the received via eBGP and by default, BGP does not redistribute prefixes learned from iBGP.

Best Regards.
