Priority in OSPF is mainly used to influence/determine a designated router/backup designated router for a network. By default, the priority is 1 on all routers. A router with a high priority will always win the DR/BDR election process.

If the OSPF process numbering is inconsistent on PE routers in the MPLS VPN, the domain-id OSPF mode command should be used to mark that the OSPF processes with different numbers belong to the same OSPF domain. This means that, in many practical cases, you can use different autonomous system numbers for the same OSPF domain in your network.

router ospf 1. redistribute static . Or you could create a loopback address and assign a 200.0.0.0 ip on it then add a network statement under OSPF. Ex . int loopback0. ip address 200.0.0.1 255.255.255.0. ip ospf network point-to-point <---- you need this command or you will only advertise a /32 . router ospf 1. network 200.0.0.1 0.0.0.0

Because everywhere it is mentioned about LSDB synchronization during new adjacency formation but find very little articles what happens when a link goes down and how OSPF updates it to it's domain. In a Network currently OSPF is stable (all routers inter area and intra area synchronized their database) and running fine.

clear ip ospf proc restarts the process andall OSPF neighbors are restarted. What implications could it have using this command in a big network infractructure and what is the reason for a big company to use it? what kind of fault would an engineer encounter in the network for him to use this command to resolve the problem.

He also mentioned how EIGRP is preemptive if the Successor route goes down and comes back up later. I wanted to test that theory with OSPF. I allowed the network to initially converge and then shut down the interface to the Designated Router. The EIGRP Successor and the OSPF DR are two totally different concepts.

I am using eve for this. Thanks for your time for testing it. Yes, it is happening like that. After configure alone for vrf definition X and rd value. After, I assigned to this X vrf into the interface which has been already enable for global OSPF routing, the router LSA doesn't withdraw from its LSDB (Here is R1) and it is still adver

HI! Adding something else about number of OSPF Area . Areas are identified by a 32-bit Area ID. The Area ID may be expressed either as a decimal number or in dotted decimal, and the two formats may be used together on Cisco routers.
