NOTE:
OSPF external route filters apply only to routes learned from RIP, EGP, or
static routes.
Before you begin, make sure that filtering support is enabled for IP in
NIASCFG. Otherwise, filtering will not work.
To configure OSPF external route filters, complete the following steps:
1
Load FILTCFG, then select the following parameter path:
Select Configure TCP/IP Filters > OSPF External Route Filters
2
Select Status and toggle the choice to read Enabled or Disabled .
Any configured filters immediately become active (enabled) or inactive
(disabled).
3
Select Action and toggle the choice to permit or deny the routes in the
filter list.
If permitted, all matching routes are forwarded by the router. If denied,
all matching routes are not forwarded by the router.
4
Select Filters.
This lists the routes that are permitted or denied, according to the Action
parameter setting.
5
Modify the route list.
Select a filter from the list and press Enter to modify the filter or Del to
remove it. Press Ins to add a new filter.
If you are modifying an existing filter or adding a new filter, modify the
following parameters from the Define Filter menu:

or Network as the type of route to be filtered.
