IS-IS. Make sure the route map you specify includes the set tag command that defines
a tag value for the routes destined for IS-IS. For details about configuring and using
route maps, see JUNOSe IP Services Configuration Guide .
To redistribute IPv6 routes, issue the redistribute command from within the IS-IS
IPv6 address family.

Configuring Global IS-IS Parameters
Use the access-list command to create a standard or extended access list.
Use the route-map command to create a route map.
For detailed information about configuring access lists and route maps, see
JUNOSe IP Services Configuration Guide.
Example For IP route redistribution the access list filters IP routes; for IPv6
route redistribution, the access list must filter IPv6 routes.
Configure three static routes:
1.
host1(config)#ip route 10.20.20.0 255.255.255.0 192.168.1.0
host1(config)#ip route 10.20.21.0 255.255.255.0 192.168.1.0
host1(config)#ip route 10.21.0.0 255.255.255.0 192.168.1.0
Configure an access list with filters on routes 10.20.20.0/24 and
2.
10.20.21.0/24:
host1(config)#access-list boston permit 10.20.0.0 0.0.255.255
Configure a route map that matches the previous access list and applies an
3.
internal metric type:
host1(config)#route-map 1
host1(config-route-map)#match ip address 1
host1(config-route-map)#set metric-type internal
Configure redistribution into IS-IS of the static routes with route map 1:
4.
host1(config)#router isis testnet
host1(config-router)#redistribute static ip route-map 1
Use the show isis database command to verify the effect of the redistribution

(that two static routes matching the route map are redistributed as level 2
