In OSPFv3, the router ID is determined by selecting the highest IP address assigned to an active interface on the router. If no interfaces are available, OSPFv3 will use the highest IPv4 address among the router's loopback interfaces, if configured. If no loopback interfaces are present, and no active IP addresses are available, the router ID remains undefined until one is assigned or the router is restarted. The router ID is essential for uniquely identifying the OSPFv3 router within an OSPF network.
it should be on back of router!
No router eigrp <AS #> No router ospf <process ID> No router bgp <AS #> No router rip
The router ID is used to uniquely identify each router in the OSPF routing domain.If no loopback interfaces are configured, the router chooses the highest active IP address of any of its physical interfaces.
Two multicast addreses exist for OSPFv3 ff02::5 ff02::6 - used by the DR to create a virtual node to represent the Network Link LSA
The router ID for RTD (Routing Table Database) is typically a unique identifier assigned to a router in a network, often represented as an IPv4 address. It is used to distinguish between routers in a routing protocol and can be manually configured or automatically assigned based on the router's interfaces. To find the specific router ID for a particular RTD instance, you would need to check the router's configuration or the output of a routing protocol command.

What is the network ID of 199.255.255.9?
A routing table has columns for at least three types of information, Network ID, the Cost and The ID of the next Router called Next Hop.
Configure the router ID on both routers. Configure the R2 router interfaces for area 0. Configure a loopback interface on both routers. Configure the proper subnet masks on the router interfaces.
