Attached diagram is my scenario ...
In order for the primus router to reach Verizon, there should be 2 routes in the routing table (or EIGRP topology table)
1. Via the Metro Ethernet link
2. Via AAPT through to metro ethernet to Verizon ;
but I see only 1 route which is the second one (Via AAPT). If i would shut/no shut the interface on primus router (i.e WAN 172.16.0.82/28),then it would get that entry in the routing table directly via metro ethernet; only until EIGRP dead timer after which it recieves EIGRP goodbye message and entry is not there in routing table anymore. So what I have to do is to shutdown the link between AAPT and Primus and now I can get entry from Primus to Verizon subnet directly via Metro ethernet.
Now, when I didnt had the link shut down, on my primus router, i was only getting entry of Verizon's subnet (203.x.x.x subnet) and no second entry was there in the topology table. Ideally, It should have had another entry saying that directly connected link between primus and verizon was backup entry but it was not...
Attached is a zip file showing scenario diagram and my topology. if am not able to explain the problem, please let me know ....
