Configuring Table Maps; Configuring Graceful Restart - Juniper IGP - CONFIGURATION GUIDE V11.1.X Configuration Manual

Configuring Table Maps

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.

Configuring Graceful Restart

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:
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.
