Table of Contents

Every graceful restart enabled router's HELLO PDUs includes a restart TLV. This

restart enables (re)starting as well as the existing ISIS peers to detect the GR

capability of the routers on the connected network. A flag in the Restart TLV

contains restart request (RR), restart acknowledge (RA) and suppress adjacency

advertisement (SA) bit flags.

The ISIS graceful restart-enabled router can co-exist in mixed topologies where

some routers are graceful restart-enabled and others are not. For neighbors that

are not graceful restart-enabled, the restarting router brings up the adjacency per

the usual methods.
