Unknown Syslog message (BGP)

Hi all!

I get the following loggings on a router, searched the net but didn't find anything! Does someone know what it mean?

- X received in update for prefix 65005:811:10.40.0.0/16 from 172.16.105.1

- *May 9 16:07:41: %BGP-3-INVALID_MP: Invalid MPLS label 3

Thanks for any help!

Re: Unknown Syslog message (BGP)

Hello,

How did you achieve this? I would be interested what you configured to end up in this situation!

Label 3 is the implicit-null label, otherwise also called "pop". This should not occur in a MP-BGP update, because the VPN label should identify the "customer context". Label 3 means: remove the top label! Thus in any case the packets following this LSP would end up - at best - in the global routing table of the PE. This is not where they usually should be ending up.

Thus the router is complaining about the - for a VPN route - invalid label.

Hope this helps! Please rate all posts.

Hi Martin!

Grüsse nach Deutschland (aus Österreich)! I get these messages on several other PE routers when a link to a special PE fails. How can this happen? Any idea??

Greets!
