OSPF and default route

I have configured a 4510 switch for a customer and they are wanting me to connect it to their wan router. They are asking me to setup OSPF on the 4500 advertising a few of the networks. Internet bound traffic will also have to traverse the wan router. The customer does not want the default route 0 0 statement on the 4500 to be advertised into OSPF. As long as I don't have the default-information-originate command in the OSPF process the default route won't be advertised right?

router ospf 13

network 161.X.X.X area 13

network  10.X.X.X area 13


ip route 161.X.X.1 points to the wan router

4500>>>>>>>>2951 wan router>>>>>>>>>>>>DS3 LINK>>>>>>>>>>>>>>WAN ROUTER>>>>>>>>>>>>>>>Internet

OSPF and default route

Hello Joel!

You are absolutely correct by not using the default-information-originate command, the default zero route will not be advertised.

I recommend a couple of Cisco Press books on routing that I keep handy when I have a senior moment. They are:

CCNP ROUTE Portable Command Guide by Scott Empson and Hans Roth

CCNP Routing and Switching Quick Reference by Denise Donohue, CCIE No. 9566 and Brent Stewart.

Best Wishes,

Richard S.
