mpls_ldp[1240]: %ROUTING-LDP-4-PEER_DUP_ADDRS : VRF 'default' (0x6000

[psymonds7769]

Getting this error message in the log:

mpls_ldp[1240]: %ROUTING-LDP-4-PEER_DUP_ADDRS : VRF 'default' (0x60000000), 1 Duplicate address(es) advertised by more than one peer

I'm not seeing more than 1 LDP peer advertising this IP however.

Duplicate Peer Addresses DB
===========================
Address: 10.16.135.94
peer 10.16.128.146:0 (pp 0x4a8ad034)

10.16.134.234 10.16.135.70 10.16.135.81 10.16.135.94

Am I correct that only seeing 1 LDP peer means that there are not multiple peers that have this address bound to it, and that it's possibly a cosmetic bug?  I've configured a logging suppress rule in the meantime.

Thanks for the information @psymonds7769 ,

You can clearly see in this output the this address is bound two different LDP neighbors.
