3620 with 2 T1 lines to a 3640 (in the central office). I would do a show ip route and both lines would show up for the subnet in either router.
3620 with 3 t1 cards. (two are the same - 1 new). But, the new one is going to a 2821 at another location. Between that 2821 and the 3640 is a 6506 (sup 720) and a 4506 (sup iv). The 3640 sees all three routes. The 6506 (directly connected to the 2821) sees only the route through the 2821, and the 4506 only sees the one through the 3640. The 2821 only lists the one through it's t1 to the 3620. All routing is EIGRP.
you need to look at 4506 and 6509 switch wherther EIGRP routing is available there or not.and what is the connectivity between 3640---4506----6509----2811 devices as bosalaza suggested show output will definitly be a good way of troubleshooting and finding the problem.
