hi i am getting a below error message in a 3560 switch

%DUAL-5-NBRCHANGE: IP-EIGRP 1: Neighbor 172.31.1.2 (GigabitEthernet0/1) is down: retry limit exceeded
%DUAL-5-NBRCHANGE: IP-EIGRP 1: Neighbor 172.31.1.2 (GigabitEthernet0/1) is up: new adjacency
%DUAL-5-NBRCHANGE: IP-EIGRP 1: Neighbor 172.31.1.2 (GigabitEthernet0/1) is down: retry limit exceeded
%DUAL-5-NBRCHANGE: IP-EIGRP 1: Neighbor 172.31.1.2 (GigabitEthernet0/1) is up: new adjacency

the other end is not learing eigrp routes from this switch..can you let me know what will be the possible issue on this

Hi,

I encountered the same error before and in my case, it was a firewall in between two border routers that was causing the problem.
