Got a CDP problem. My distribution switch are not in the cdp table of the core switch. The core is in the cdp table of the distribution switch.
1 Distribution has many vrf (switchport with vlan interface)
1 Distribution has on vrf (L3 interface)
In the debug, distribution are sending and receiving cdp packet. Core is sending but not receiving any.
This problem is only on tenGig ports. My others distributions still connected with Gig etherchannel have no problem.
Any idea ?
