I have three border routers that all connect to different ISP's. These border routers all receive bgp derived default routes along with a few other important routes. I want to redistribute the BGP AS into my OSPF AS except for the default route. I know I can do it simply by not configuring default-information originate under OSPF, but I wanted to try and do it based on BGP route tags.
Is there a way for me to assign the default route derived from BGP a tag that I can filter when I redistribute into OSPF?
