I also upgrade to 12.4(25) last night and no change in the issue. The same
issue still remains.

It does. I've seen it before years ago.
get 'sh ppp multilink' from the RSP and VIP console (if-con slot)
and sh contr cbus.
Make sure you are in dCEF mode, all links are on the same PA, and on
later(est) 12.4 mainline (12.4(25) or 12.0(32)S(latest)) on Cisco.com.
We had bugs in how we manage the member links of the bundle.

When it happens, I can ping the remote end from the 7513, but nothing
outside of the 7513.
For Example....
SERVER --ethernet--- 7513 ---multilink (2 T1's)--- END USER
1 multilink T1 bounces.
After the T1 comes up, the multilink interface and both T1's show as
up/up
and 7513 can ping END USER, but END USER can't ping 7513 and no
connection
to/from SERVER to END USER.
Hope that makes sense.

That should never happen and is possibly a bug.
Can you ping directly over the bundle to the ip address on the other
side when it's broke? If not, go to the latest code and see if it's
fixed...or do some debugging: 'sh ip cef for other side of bundle, debug
ip packet, etc...

We have several customers setup with T1's multilinked. We are running
into
a problem with a single multilink member bouncing causing routing
issues.
When a single T1 member of a multilink group bounces, traffic to the
overall
multilink interface stops and we have to manually shut and no shut the
multilink interface to get traffic flowing again.
Has anyone seen this before and if so, know what the issue may be?
