Is there a recommended practice to control/manage multiple default routes as more and more of our OSPF areas/markets get their own Internet?
Is it just using filters/route maps? (OSPF area filtering?) I thought of adjusting the E1 metrics for each default-orig but this may not be possible today without some testing and maintenance windows.
Bringing up a new Internet for an ospf area that has several ABRs and trying to avoid static 0/0 routes from ABR to ABR to get to the FW and would like to have the FW generate the default route but I do not want that route getting to our core and other non-stub areas.
