Hi, i just upgraded from 3.9 to 3.10, now i cannot see cisco neighbors anymore in the neighbor list??
but i can see mikrotik neighbors.
anyone having the same issue? has CDP been removed from 3.10?
l liked this feature… 
Make sure that you have ‘ip neighbor discovery’ enabled for the particular interfaces.
I have router with 3.10 and Cisco router is shown in ‘ip neighbor print’,
21 ether1 10.0.11.202 00:17:5A:90:66:08 C7200 Cisco I... none
Is CDP still open in version 5.0 ?
I can see Mikrotik Routers from a windows LLDP agent, but the opposite is not true. Router OS does not see Windows CDP agents.
(firewall is disabled on Windows agents).
My v5.x RouterOS is able to see CDP neighbors.
