Injecting a default route into OSPF

quist — Thu, 26 May 2011 16:06:01 GMT

I have an OSPF virtual router configuration with two interfaces. One interface (int1) is part of the default area (0.0.0.0) whereas the other one (int2) is not. There is a static default which points to the next hop on the non-OSPF interface network.

I want to announce or generate a default route into the OSPF area and have clicked the "Allow Redist Default Route" button. However the default does NOT get announced to the OSPF cloud. Do I have to create a Redistribution Profile as well to make this "standard" operation occur?

Likely the route is not getting announced because the OSPF peer likely does not have a route to your interface subnet that has the default route. I would expect that at least redistributing your connected routes would be required since the next hop is on a non-OSPF interface.

Quist,

For the PAN to advertise the default route, in the export rule, please add 0.0.0.0/0 and commit the config, this will advertise the default route to your OSPF peer routers. Below is the snapshot of how the config will look like.

Hope this helps, do please let us know if this worked for you.

Thanks
