What is the type of link between the devices - does it support multicast?

What happens is you use the neighbor command to force unicast?

Please provide configrations and run "sh eigrp plugins" on both to check versions.

Also check "sh ip eigrp events"

And then turn on debugs
debug ip eigrp neighbor

I was just working with a customer that has a 3850 - 24 port that continually sends goodbye tlv every 80 seconds


He also has a 3850 48 port that works fine


The 3850 24 port can NOT ping at all

The 3850 48 port can ping and gets responses from all the eigrp neighbors on the vlan


Router eigrp 1 configs are same
