Hi.
Just to follow up on my previous post, I found out the problem had
something to do with the Remote router's PHYSICAL BRI interface, which
appears defective. I replaced it with another router and this config on
Caslow's book works. I realized it worked for me before, but I replaced
the remote router to be able to do a different topology and found out
what the issue was. Thanks for the replies.

If your routers are configured exactly as you have listed down there,
it's because you don't have a dialer map on the other side. The one
side is sending out, but the other doesn't have a clue who it's
connected to in order to send things back.
If you were to use dialer maps without the 'name' part, you'll have two
uni-directional channels come up. If you use the 'name' feature, you'll
get traffic bidirectional over a single B channel.
If you do a 'debug ip icmp' or 'debug ip packet' on the second router,
you'd likely see things like encapsulation failed messages or something
similar. I don't have his book in front of me, so sorry I can't give
you better insight other than what you've listed as the config!

Subject: Caslow's Dialer Map with PPP example
Hello gang.
I'm testing Caslow's sample configuration on Dialer Map with PPP on page
173, but can't figure out why the BRI channel would be UP yet the
routers can't ping each other. Unfortunately, he has no follow up on
this AFAIK. Please tell me what it is he's trying to say and I'm not
seeing. Thanks.
