Hello Guys,
Currently I'm in the process of implementing L3 links for our campus network.
I'm having following issue with EIGRP routing.
1. 6509 core switch (L3)
2. 4510 access switch (L3 uplink /L2 access)
I have created port channels (for bandwidth aggregation) between 6500 and 4500 switch.
Issue is i'm unable to route or see the route updates from eigrp on core switch for the vlan on Access switch.
Following is the configuration from both 4500 switch and 6500 switch.
Please let me know about the missing configuration.
