ospf on pix

EXISTING SETUP:

My customer is on a flat network on a certain OSPF Area. ABR connects the area to the OSPF AS.

THE PROBLEM/QUESTION:

Iam now inserting the PIX 515E UR between my customers network and the ABR.

Do I need to implement OSPF on my PIX even if my customer remains a flat network?

Thanks.

If you need OSPF contunuity across the network you have to enable OSPF on PIX, Alternatively, you can rely on static routes.

HTH

but how will the pix speak to the abr which is talking ospf?

The PIX has to be configured with OSPF.

Thanks.

you have mentioned that i could do static as an alternative. is this possible without doing any redistribution on the router?

thanks

You can configure static routes w/o redistribution. Redistribution only injects your static/connected/learned networks into a routing protocol. No routing protocol, no redistribution.

If you have a single homed network, you don't necessarily need dynamic routing.

HTH.

iam just one of the site (area) among the 20 ospf areas in the whole AS.

is this being considered as single homed?

thx

If your link to the backbone area is a single connection then you are single-homed.

If you go static, you would still need to insert routes for your area via ABR into your backbone. ABR will become an ASBR.

Thanks.
