Usage Information
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.
graceful-restart interval
Set the graceful restart grace period, the time during that all graceful restart attempts are prevented.
Syntax graceful-restart interval minutes
