Routes are redistributed from the Nokia OSPF network to the Corporate RIP
Network.

on the home page.
3.
Click the Route Redistribution link under the Routing Configuration

7.
Assume that Nokia Platform B has another interface not shown in the
picture and that it has two additional OSPF routes:
10.0.0.0/8
and
10.1.0.0/16.
Assume that you want to exclude all routes that are strictly
more specific than
10.0.0.0/8;
that is, we wish to propagate
10.0.0.0/8
itself, but we do not propagate the more specific route.
a.
To configure this filter, we add
10.0.0.0
in
N
EW
IP
PREFIX TO
IMPORT
entry box, and
8
in
M
ASK LENGTH
entry box; Click A
PPLY
.
b.
Select
REFINES
in the
M
ATCH TYPE
pulldown menu. This specifies
that we want routes that are strictly more specific than
10.0.0.0/8
.
c.
Finally, click on
RESTRICT
in the
A
CTION
field. This specifies that we
want to discard the routes that match this prefix.
d.
Click A
PPLY
. The filter is fully configured.
