MPLS labels illegals

[antoniolv]

Good morning:

We have a router 7204VXR that it is sending messages trap of labels MPLS illegals. Do you know some form of detecting the origin that is generating this problem? as I can know that it labels has the problem? can I activate some debug that me of some information?. It is a message that gives occasionally and I don't want to leave activated a debug mpls events during long time.

Thanks,

Can you post the trap or syslog message that you receive.

Hi, hritter:

The trap is the following one:

"This notification is generated when the number of illegal label violations on a VRF as indicated by mplsVpnVrfSecIllegalLabelViolations has exceeded mplsVpnVrfSecIllegalLabelRcvThresh. The threshold is not included in the varbind here because the value of mplsVpnVrfSecIllegalLabelViolations should be one greater than the threshold at the time this notification is issued."

Enterprise Name: mplsVpnMIB .1.3.6.1.3.118

Event Name: mplsNumVrfSecIllegalLabelThreshExceeded .1.3.6.1.3.118.0.5

As I can see this information in the router when it is happening?.

Thanks,

This trap is issued when illegal labels are received from a VRF. By illegal label we mean label that we are not expecting.

Are you running MPLS on the VRF interface?

This trap is defined in the following draft:
