Is 90% of the traffic from the 3640 LAN to the 7513 LAN between the same
source and destination pair?

Subject: load balancing problem
We have an issue that seems to have no resolution.
We have a 7513 and 3640 connected using 2 T1 serial links. EIGRP, IP CEF
per destination load sharing, and LLQ for voice traffic are configured. The
EIGRP metrics indicate that the links are indeed equal.
LAN traffic behind the 7513 going to the LAN behind the 3640 seems to be
load balance, within reason. LAN traffic behind the 3640 going to the LAN
behind the 7513 favors one of the links 90% of the time. So the traffic is
not load sharing like it should.
Routing and CEF tables look fine. Just can't find an explanation as why the
traffic is favoring only one of the links.
Opened TAC case - but they said it should be working and are researching the
issue.
Ever see anything like this before? Any troubleshooting commands that would
help identify the cause?
Thanks,
Tim
