I have a question on a CCIE Lab. Lets's say I have a 4 router setup in a linear fashion
HA------RA<--->RB<--->RC<--->RD-------HB
Let's say HA is in the network range of 10.0.0.0/24 as well as HB. So I configure RA for bridging
and include the FA0/0 intf going to HA and Serial interface going to RB in bridge-group 1. I also setup
the correct BVI. Since I have multiple routers between HA and HB do I need to configure a BVI interface
on each of the intermediate routers or just setup BVI interfaces on RA and RD, and the rest include
bridge-group 1 so the BVI knows what bridge-group it belongs to?
