Just an update to you all..
We managed to bring up the L2TPv3 tunnel between a pair of 3745
routers with some latest IOS.. Now i have another challenge..
I need to build a parallel bridging path (for HA reasons) with another
pair of routers and bridge the same set of networks.. Is this
supported...? If so, how would the bridging loop be taken care of ?
BPDUs dont seem to be flowing across the pseudowire..!
Any thoughts..?
Regards
