Um...
Broadcasts can be sent. How does IGRP and RIPv1 usually send their routing updates.... 255.255.255.255 . Without the neighbor statement of course.
your right without bridging or IRB ....etc included in this discussion broadcasts will not propagate thru a router ----e0-router1-s0-----
from e0 to s0 if that was what Chuck was talking about. I don't know. Tell me to go back to sleep and I will :)

I'd guess it's all layer 2 things - keepalives, inverse arp, maybe
LMI. Not IP broadcasts.

Subject: Why Serial interface receive broadcasts packets?
Hi,
I thought router will break broadcast traffic. So only the ethernet
interface
could recive broadcasts packets. Now I got a Serial interface receive
broadcasts packets.
