AIS AI2524 Examples Clns Filter, Redistribute Routing Information, Clns access-group name in out

Chapter 9: AI2524 OSI/CLNP Configuration Steps

2.In interface configuration mode, apply filter expressions to an in- terface:

zApply a filter expression to frames forwarded in or out of an inter- face.

clns access-group name [in out]

zApply a filter expression to ISIS adjacencies.

isis adjacency-filter name [match-all]

zApply a filter expression to ISO IGRP adjacencies. iso-igrpadjacency-filtername

zApply 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:
