Need your quick help on EIGRP Stub functionality for routed access layer design:
1)We have 2*CAT4503 E's installed with SUP6L-E cards and connected together via 2*10GBE port channel configured as layer 2 at the moment. As SUPL-E only supports EIGRP Stub, would my plan towards routed access layer (CAT3560's) work or do I need to upgrade the SUP card?
2)Does EIGRP Stub needs to be configured on the Access layer stacks only or distribution switches as well? If it require configuration on Distribution switches then do I need to convert my l2 port channel to l3 port channel and turn on EIGRP Stub on it as well? Or Do I need to have full EIGRP on the distribution switches and EIGRP Stub in access layer?
3)We have all access layer stacks connected via dual uplinks to CAT4503's and running PVRSTP. Does configuring EIGRP Stub provide ECMP to load balance the traffic over two diverse paths?
