Command
History
Version 9.0(1.3) Introduced on the S5000.
Usage
Information
Every graceful restart enabled router’s HELLO PDUs includes a restart TLV. This
enables the (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.
