Hi ! I have the following network setup running ospf, ibgp within the Domain and ebgp beween AS. GW: Gateway router BB: Backbone Router Note: BB and GW router is connected directly (cross-connect) and the Area0 is extended from BB to GW router. Pre-requisite: LAN on Area 11 shud able to access both the routers for redundancy. Implementation : Implemented HSRP between BB and GW and extended the Area 0 using cross ethernet back to back cable between BB and GW. Route-reflectors are confgured on IBGP routers and EBGP on GW routers. Both the GW routers are connected to the same ISP. Preoblem : sometimes I am getting routing loop between BB and GW routers when trying from Area 11 LAN( default Gateway for all the machines is GW). Action taken: Checked the ip route and gound that the defualt gateway on GW is pointing to Internet interface and for BB it is pointing to GW. The looping occured between the back to back connected interface. Can any body suggests the way to troubleshoot the problem _____________________________________________________ Chat with your friends as soon as they come online.
