You can use the table-map command to apply a specified route map as a policy filter
on an IS-IS route before the route is installed in the routing table. The route map you
apply must contain one or more set commands to modify route attributes.
Use to apply a policy to modify distance, level, metric, metric type, origin, preference,
route type, or tag values of IS-IS routes about to be added to the IP routing table.
The router applies the new route map to all routes currently in the forwarding table
and those about to be installed in the forwarding table.
If any previously redistributed routes are changed as a result of applying the route map,
the router redistributes these routes again with the changes caused by the route map.
The router removes from the forwarding table any old routes that are now disallowed
by the specified route map.
Issue the command from the IS-IS IPv6 address family to apply a specified route map
as a policy filter on an IS-IS IPv6 route before the route is installed in the routing table.
IS-IS IPv6 supports only a single table map.
Example
The following commands apply a policy (route map) named metricTypeExt to modify
the metric type of IS-IS routes configured with a route tag value of 33.
host1(config)#route-map metricTypeExt permit 5
host1(config-route-map)#match tag 33
host1(config-route-map)#set metric-type external
host1(config-route-map)#exit
host1(config)#router isis marketing
host1(config-router)#table-map metricTypeExt
host1(config-router)#exit
host1(config)#exit
Use the no version to halt application of the route map.

To enable IS-IS graceful restart (also known as nonstop forwarding, or NSF) on the router,
you must first issue the nsf ietf command (in Router Configuration mode). You can then
configure one or more optional timing parameters for graceful restart on the router.
To enable IS-IS graceful restart and configure optional graceful restart parameters:
