IS-IS RIB

---

Use the IS-IS RIB table to view the Intermediate System to Intermediate System (IS-IS) protocol routing information base (RIB). IS-IS is an OSI link-state hierarchical routing protocol that floods the network with link-state information. This enables network elements (NEs) to build a complete, consistent picture of a network topology. The IS-IS RIB effectively displays the network view from the perspective of the IS node.
