    Understanding Static Routes for CLNS

    The Connectionless Network Service (CLNS) is an ISO Layer 3 protocol that uses network service access point (NSAP) reachability information instead of IPv4 or IPv6 prefixes.

    You can configure static routes to exchange CLNS routes within a CLNS island. A CLNS island is typically an IS-IS level 1 area that is part of a single IGP routing domain. An island can contain more than one area. CLNS islands can be connected by VPNs.
