The problem: i have my BGP AS, and i make ibgp peering between R1<->SW<->R2 and i am using for this my BGP AS network segment. In general this is dual multihoming. R1 - my main router. R2 - backup. at my SW - there are my BGP AS which presents like a vlans.
The question is:
When my R1 is UP -> i can't ping SW iBGP ip.
When R1 goes down and R2 is main router - the ping is accept.
