OAL provides hardware support for ACL logging and permits or drops packets in. Based on this finding, I found this link Redistributing Connected Networks into OSPF. OSPF uses the address of the loopback interface as the OSPF identifier, so this example will set the address of the loopback interface, then enable OSPF with a process ID of 100, and distributing a network of. It's the highest IP on the router by default. The costcommunity ID is either 128 or 129. Metric -1, Type 0, Tag 0 10. Any EIGRP EXT route that doesn’t exist in OSPF will show up on one of the routers as preferring OSPF due to lower admin distance, breaking EIGRP->OSPF redistribution on one router. The keyword internal indicates the OSPF intra-area and interarea routes: External 1 is the external route type 1, and external 2 is the external route type 2. There is another way to configure route leaking between VRFs. Therefore, when a router executes a route-map, the router interprets only the commands which make sense in the context of route-map application. I'm looking to redistribute static routes in to OSPF on a Nexus 7k. 0 Cisco Common Routing Problem with OSPF Forwarding Address.
