Hi Chris, Just want to note one mis-undertanding below..
Chris Parker <[email protected]> writes:
Even if we were to talk about level 1, it is possible for an L1 router to be in two IS-IS areas at once, which is a way of creating a single L1 topology, a single LSP flooding domain.
An IS-IS router instance can only be in one area not multiple. IS-IS differs from OSPF in that area boundaries exist "on the wire" (i.e., between routers) and not inside the router instance as they do with OSPF. An IS-IS router instance is only ever in one area. Thanks, Chris. [as wg-member] P.S. I don't think you are referring to the ability in IS-IS to refer to an area with multiple identifiers.. _______________________________________________ Lsr mailing list [email protected] https://www.ietf.org/mailman/listinfo/lsr
