As soon as OSPFv3 is enabled on the Stub Router, it sends out OSPFv3 Type 1 Hello messages to the FF02::5 multicast address. Once it receives Hello packets from the ABR1 Router, they negotiate the Primary/Secon
This document describes the Open Shortest Path First (OSPF) Link State Advertisement (LSA) Type 5 External Route Selection mechanism. It presents a network scenario with the configuration for how to select the route received from one Autonomous System Boundary Router (ASBR) over another. Prerequisite...
OSPF Configuration Example - network The same example as before for EIGRP, we have R1 here. FastEthernet0/0 has got IP address 10.1.0.1/24, FastEthernet1/0 is on the 10.0.1.0/24 network, and FastEthernet2/0 is on the 10.0.2.0/24 network. We could put in 3 separate network statement...
That completes our OSPF configuration on R1, R2, and R3 and its time to verify if our configuration works as expected. If we configured OSPF correctly R1 should have established OSPF adjacencies with both R2 and R3. Let’s see if that’s the case: R1#show ip ospf neighbor Neighbor ID ...
