ASR 9K : Duplicate addresse in MPLS

[zizou6500]

Hi Community,

This line keeps showing up on my device logs in a daily basis:

RP/0/RSP0/CPU0:2023 Aug 14 13:46:37.524 UTC: mpls_ldp[1240]: %ROUTING-LDP-4-PEER_DUP_ADDRS : VRF 'default' (0x60000000), 1 Duplicate address(es) advertised by more than one peer

Iv'e found the culprit IP (using commnd "sh mpls ldp structs dup-addr"), however I'm not sure how to deal with it and I'm suspecting this is impacting traffic and leading to packet losses.

Could you please advise on this?

Hello @zizou6500,

Do you have a clear understanding of the devices that are advertising this duplicate IP ?
