Thunai,
This is the normal behavior of IS-IS. The routing process
treats IS-IS differently than the other IP based protocols. One of the
effects of this is that when you redistribute IS-IS into another
protocol, only the routes that are listed as IS-IS in the routing table
are redistributed. This implies that connected interfaces (which are
listed as connected) will not get redistributed. To resolve this,
simply issue the redistribute connected statement.
This used to be an issue with OSPF until they changed the code
to have it include the connected interfaces. As of 12.2T however, the
IS-IS code has not been updated to include this.
HTH,
Brian McGahan, CCIE #8593
