Configuring Redistribution

Example
host1(config-router)#domain-authentication csnp
Use the no version to restore the default behavior, in which authentication of level 2
CSNPs and PSNPs is disabled. When authentication of level 2 CSNPs or PSNPs is
suppressed, the router does not authenticate these packets when it receives them,
nor does it send authentication information in these packets when it transmits them.
See domain-authentication
You can specify how IS-IS redistributes routes received from other routing protocols,
redistributes routes according to new policies, and controls redistribution of routes with
access lists and route maps.
Optionally, when you issue the redistribute command and specify a route map, you can
use the map to set a route tag for a route redistributed from another protocol to 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.
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 10.20.21.0/24:
2.
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 internal
3.
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:
