IRB

Question.. I have two routers running IGRP over a frame link. When I turn on
IRB on router A (Bridging and Routing IPX, Decnet, Appletalk, IP), router B
stops receiving IGRP updates from router A. When I do a "debug ip igrp
events" on Router A it shows I am still receiving updates from router B and
sending updates out Serial 0. However, issuing the debug igrp command on
router B shows router B is sending updates, but is not receiving IGRP
updates from anyone. Even more strange is the fact that I cannot ping either
serial interface from either side when IRB is turned on!

RouterA-S0: <----IGRP----> :S0.1-RouterB

Seems like a simple scenario. However, as soon as I type "bridge irb" on
router A, router B no longer receives IGRP updates from
router A... Am I missing something obvious here? I am hoping for one of
those obvious gotcha answers since I am too tired to figure this out
tonight.. :D (config below)

Thanks.
