HI,

I`M TRYING TO GO INTO THE DEPTH OF IT..

assume you have a router with four interfaces / all ethernet

two of them [1 and 2] are in one brigde group

ethernet 1
ip address 10.10.10.1 255.255.255.0
bridge-group 1

ehternet 2
ip address 20.10.10.1 255.255.255.0
bridge-group 1

ethernet3
ip address 30.0.0.1 255.255.255.0

QUestion..

Between Interface 1 and 2. all protocols being bridged but IP....it is
routed....!

? Does IP communication between 1 and 3 or 1 and 2 work ???

i guess yes..but where is the benefit of CRB vs..the config above ???
