Hi there,
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.
Configs:
R1-
router bgp AS
bgp log-neighbor-changes
network x.x.x.x mask 255.255.252.0
timers bgp 15 45
neighbor x.x.x.2 remote-as AS -iBGP peer
neighbor x.x.x.2 next-hop-self
neighbor x.x.x.3 remote-as AS - iBGP peer
neighbor x.x.x.3 next-hop-self
neighbor x.x.x.x remote-as AS - eBGP peer
neighbor x.x.x.x soft-reconfiguration inbound
neighbor x.x.x.x route-map ISP1_in in
neighbor x.x.x.x route-map ISP2_out out
R2-
router bgp AS
bgp log-neighbor-changes
network x.x.x.x mask 255.255.252.0
neighbor x.x.x.x remote-as AS
neighbor x.x.x.x soft-reconfiguration inbound
neighbor x.x.x.x route-map ISP2_in in
neighbor x.x.x.x route-map ISP2_out out
neighbor x.x.x.1 remote-as AS - iBGP peer
neighbor x.x.x.3 remote-as AS - iBGP peer
SW-
