WebIS-IS Hello packets are used to discover neighbors on a link. Once the neighbors are discovered, they act as keepalive messages to maintain the adjacency. IS-IS standard recommends that IS-IS Hello packets must be padded to within one octet less than the size of the MTU. There are two types of Hello packets: LAN Hellos and Point-to-point Hellos. WebThis protocol originally was developed for routing International Organization for Standardization (ISO) Connectionless Network Protocol (CLNP) packets. Like OSPF routing, IS-IS uses hello packets that allow network convergence to occur quickly when network changes are detected. IS-IS uses the SPF algorithm to determine routes.
