Transparent bridging

 | 31 Jul 2007 18:16

Two things I learned today about bridging:

1) When bridging on a router that is only forwarding the bridged traffic it’s best (not needed apparently) to turn off ip routing:

no ip routing
!
bridge <123> protocol ieee

2) When bridging and routing IRB or CRB then it’s advisable to enable routing within the bridge-group:

bridge irb
bridge <123> protocol ieee
bridge <123> route ip

IRB = Integrated Routing & Bridging
CRB = Concurrent Routing & Bridging
