Scratch that, ...sorry. You only need 'bridge crb' when your trying to
bridge a particular protocol that is set up for routing on another interface
on your router. IP routing is enabled by default, so if you ever wnt to
bridge IP, you'll need to bridge on every interface or set up crb. For your
senario, IPX routing is disabled by default. If for some reaseon you
enabled it on your middle router, then you'll need to disable it, or use crb
to bridge IPX on only the two interfaces described in your diagram.
....oops, Sorry. There's the accurate story.

Atif,
I you have more than two interfaces on your middle router doing the
bridging, and you do not have the bridge group command under ALL interfaces
-or- have all routing, including IP disabled with 'no ip routing', then
you'll need to tell the router to concurrently route and bridge with the
global 'bridge crb' command. IRB is not needed for this scenario as you've
described it. Good luck.

Subject: IPX bridging problem
i was working ipx ( my weak spot :) ) when i encountered a strange problem
that i cannot seem to solve. The relevant setup is like this :
Router_A(ether0/0) --- (ether0)Router_B(serial0) --- (serial1)Router_C
All the 3 routers are routing IP. Router_A and Router_C have ipx routing
turned on too but Router_B does not have ipx routing turned on. Router_A's
ethernet0/0 and Router_C's serial 1 both have the same IPX network number.
Router_B has bridge-group 1 statements on both ether0 and serial 0.
IPX RIP routes from Router_A are seen successfully in the ipx routing table
of Router_C. However, updates from Router_C are not reaching Router_A. When
i turn on debugging on Router_C it says that it is broadcasting updates out
serial 1 but these never reach Router_A. I dont think i need IRB anywhere
here ... why is this happening that one way traffic is going through
successfully and the other way its not ??? Rest assured there are no IPX
access-lists anywhere ...
TIA
