Thread Index [isp-bgp] Re: BGP session
Try having R3 peer to both R1 and R2... Use local pref. if necessary.. It's easier this way... so if R1<->R3 link is down, then so is the session. But R2<->R3 link is still up as well as the session.. -hc On Thu, Apr 17, 2003 at 09:21:14PM +1200, Jacques VUVANT wrote: > OK > > bgp session come up first with R3-R1 via link R3-R1(I use ip route > <loopback> <IP next-hop> on each router R1 and R3) > when link R1-R3 is down. each loopback are not reachable via R2.
