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.

These are not synchronized between the active and standby supervisors:
All Layer 3 protocols on Catalyst 4500 Series Switches (Switch Virtual Interfaces)
Cisco NonStop Forwarding (NSF) works with SSO to minimize the amount of time that a Layer 3 network is unavailable after a supervisor engine switchover by continuing to forward IP packets. The reconvergence of Layer 3 routing protocols (Border Gateway Protocol [BGP], Enhanced Interior Gateway Routing Protocol [EIGRP], Open Shortest Path First [OSPF] v2, and Intermediate System-to-Intermediate System [IS-IS]) is transparent to the user and occurs automatically in the background. The routing protocols recover routing information from neighbor devices and rebuild the Cisco Express Forwarding (CEF) table
