To allow OSPF to preferentially select the inter-area path passing through the high-speed link, you can configure multiple sub-interfaces and add them to different areas. However, this method increases the total number of routes because an independent IP address needs to be configured for each ...
Stub area configuration is optional, and not every area is eligible to be a stub area. In general, a stub area resides on the border of the AS.When you configure a (totally) stub area, follow these guidelines:· The backbone area cannot be a (totally) stub area....
(Totally) stub area configuration is optional, and not every area is eligible to be a stub area. In general, a stub area resides on the border of the AS. The ABR of a stub area advertises a default route in a Type-3 LSA so that the routers in the area can reach external networks...
Single Area OSPF Configuration Topology Cisco OSPF Configuration Steps First of all, we will configure the routers’ interfaces. After that we will configureOSPFas ourRouting Protocol. Here we assume that all the interfaces including loopback interfaces, their speed, duplex and descriptions have been...
Define a Not-So-Stubby Area Use the OSPF router configurationarea xx nssacommand in order to define an NSSA. For example, in this topology, Area 2 was configured as an NSSA with thearea 2 nssacommand on all routers in the area. This protects Area 2's internal routers from all the AS...
Define a Not-So-Stubby Area In order to make a stub area into an NSSA, issue this command under the OSPF configuration: Router(config)#router ospf 1Router(config-router)#area 1 nssa This command must be configured on every single router in Area 1. After you define Area 1 as an NSSA,...
difference on R4 in that topology, but as I said that isn't my interpretation of 16.4.1 (maybe were referring to different things there); R4 is a backbone node in the OP topology. Which step in RFC2328 should have R4 pick between the OPs "intra-area backbone paths and ...
Hello Forum, I’m hoping the community can provide some assistance on configuration for loop prevention & route flapping with multiple connection points given bi-directional redistribution of OSPF & BGP. Obviously the ultimately goal being a stable
R1 and R3 will not learn routes to each other because both sides are in different process IDs on router R2. The way we would configure this is on R2, we say 'router ospf 2' at global config, and then 'network 10.0.0.0', the wildcard mask, '0.0.0.255 area 0', and then for ...
