Two OSPF instances are configured for each VRF table. -Redistribution among RIP, OSPF, EIGRP and BGP (Attributes). OSPF Interview Questions,IN DR/BDR election which router is elected first?,If there are routers present in the area, which router does the conversion of LSA7 to LSA 5 ?, can we stop some specific routes entering into nssa?, How many states are present in ospf?, What are the must match parameters to become neighbors in OSPF?, OSPF Authentication Happens in Which State?. The OSPF not-so-stubby area (NSSA) feature is described by RFC 1587 and is first introduced in Cisco IOS® Software release 11. OSPF has a stub router feature (don't confuse this with stub areas) that lets you prevent a router from being a transit router. I am having problem with multi area OSPF: the ABRs do not want to advertise the routes across different areas. Configure a. OSPF stores the topology of the network in its LSDB (Link State Database) and each router is identified with its unique router ID , if you have duplicate router IDs then you will run into reachability issues. OSPF is a feature rich, multi-topology protocol that requires some effort to set up for your network’s specific needs. Networking Problems solved… one at a time. When multiple OSPF routers are connected to a multi-access medium such as Ethernet, a Designated Router (DR) and a Backup Designated Router (BDR) are elected. 1 as defined in RFC 7950 and conforms to the Network Management Datastore Architecture (NDMA) as described in RFC 8342. DMVPN and Routing Protocols – OSPF.

So up until this point you’ve learnt how to configure different routing protocols such as the Routing Information Protocol (RIP), Enhanced Interior Gateway Routing protocol (EIGRP) and Open Shortest Path First (OSPF) but now its time to learn how to make this protocols play nice with each other and share their routes between each other. Through the lab, we will show that the actual path that packets take from the source to the destination routers could be different from the shortest path associated with the smallest end-to-end total costs calculated by the source router. Hands-on configuration and operational knowledge of Juniper Networks router and firewall and switching products, passion to continue learning and expanding your knowledge. This two-part article describes the functionality and configuration of a multi-area OSPF network, along with configuration of some parameters. Bryan has 2 jobs listed on their profile. The next step in configuring OSPF is to specify which router interfaces are included in OSPF using the network command, also mentioning OSPF area the interface belongs to. OSPF routing is explicitly disabled on the management interface fxp0 to keep routing adjacencies from becoming established there in case of a mistake by operations staff. OSPF Rigid area design - all networks must have area 0 core, with sub-areas distributed around Suits ISPs with central high speed core network linking regional PoPs Teaches good routing protocol design practices ISIS Relaxed two level design - L2 routers must be linked through the backbone. Your backbone area would still be area 0 - process id is being used by Cisco to specify which instance of OSPF is running in case you have an advanced configuration with multiple OSPF processes on a single router. 0/30) and redistribute that route into OSPF. In the Cisco world, the 1 in router ospf is the process-id.
