2. In interface configuration mode, apply filter expressions to an in-
terface:
z
Apply a filter expression to frames forwarded in or out of an inter-
face.
clns access-group
name
[in | out]
z
Apply a filter expression to ISIS adjacencies.
isis adjacency-filter
name
[match-all]
z
Apply a filter expression to ISO IGRP adjacencies.
iso-igrp adjacency-filter
name
z
Apply a filter expression to ES or IS adjacencies.
clns adjacency-filter {es | is} name
Examples: CLNS Filter
This example allows packets if the address starts with either 47.0005
or 47.0023. It implicitly denies any other address.
clns filter-set US-OR-NORDUNET permit 47.0005...
clns filter-set US-OR-NORDUNET permit 47.0023...
Redistribute Routing Information
In addition to running multiple routing protocols simultaneously, the
Cisco IOS software can redistribute information from one routing pro-
cess to another.
You can also configure the Cisco IOS software to do
interdomain d ynamic routing by configuring two routing processes
and two NETs (thereby putting the router into two domains) and redis-
tributing the routing information between the domains. Routers con-
figured this way are referred to as border routers. If you have a router
that is in two routing domains, you might want to redistribute routing
information between the two domains.
Warning: It is not necessary to use redistribution between areas. Re-
distribution only occurs for Le vel2 routing.
1. In global configuration mode, configure the router to redistribute
routing information into the ISO IGRP domain:
