ISIS ACL

Unanswered Question
Feb 13th, 2007

I'd like to know how can I configure a ACL to permit the isis routing protocol?

In the acl there is no ISIS like OSPF

I have this problem too.

The ISIS protocol use protocol identifier of 0x83, it is a layer 2 identifier. IS-IS does not run over IP. You would need to use an ACL in the 200-299 range, matching on the L2 Protocol type.

You might look into the CLNS filters to do this.... 'clns filter-expr' and 'clns filter-set'.
