Abstract
The Virtual LAN Link State Protocol (VLSP) is part of the InterSwitch Message Protocol (ISMP) which provides interswitch communication between switches running Cabletron's SecureFast VLAN (SFVLAN) product. VLSP is used to determine and maintain a fully connected mesh topology graph of the switch fabric. Each switch maintains an identical database describing the topology. Call-originating switches use the topology database to determine the path over which to route a call connection.
VLSP provides support for equal-cost multipath routing, and recalculates routes quickly in the face of topological changes, utilizing a minimum of routing protocol traffic.
