%FIB-4-FIBCBLK: Missing cef table

Is anybody familiar with this message:

%FIB-4-FIBCBLK: Missing cef table for tableid 65535 during CEF samecable event

The router keeps reporting this constantly.

If you would also happen to know how to fix this it would be great thanks.

Thank for the links Giuseppe,

I found the following for a similar errors:


CSCee26209 Bug Details

%FIB-4-FIBCBLK: Missing cef table for tableid

Symptoms: When removing "ip vrf" from the configuration, the following message

is printed:

%FIB-4-FIBCBLK: Missing cef table for tableid 1 during CEF table change event.

This is also triggered when configuring a NPE-G1 interface with a vrf.

Conditions: Simple configuration with no routing protocols running.

Workaround: not known. But there is no expected impact which should

be expected from those error messages.


I don't think there is a workaround for my issue either.

However this error seems to cause no real effect.
