Extensions to IS-IS and OSPF for Advertising Optinal Router Capabilities
Redback Networks
It is useful for routers in a domain to know of the capabilities of their IGP neighbors, and/or of other routers in the domain. This draft proposes extensions to IS-IS and OSPF for advertising optional router capabilities. We define an optional Router Capability TLV for IS-IS, while for OSPF we define an optional Router Information Opaque LSA.
