I've got this working good over multiple bridged MLPPP connections. There was a thread on this previously when I had some issues with it. You basically need to use a BVI interface with the bridge to get things to work properly. Sample config that helped me get this working is below. R1/R2: Bridge irb Bridge 1 protocol ieee Bridge 1 route ip Int bvi 1 Ip add xxx Int serial Bridge-group 1
R3 (transparent bridging) No ip routing Bridge 1 protocol ieee Int serial Bridge-group 1 Int serial Bridge-group 1 ________________________________ From: [email protected] on behalf of Lee Sent: Tue 12/28/2010 7:25 AM To: Joe Freeman Cc: Cisco-nsp Subject: Re: [c-nsp] Bridging ethernet to MLPPP Have you tried it without the 'bridge irb'? It sounds like you want to bridge IP between the two sites and I think integrated routing & bridging is going to want to route IP..
