Usage Guidelines
In OSPFv3, all areas must be connected to a backbone area. If the connection to the backbone is lost, it
can be repaired by establishing a virtual link.
The smaller the hello interval, the faster topological changes will be detected, but more routing traffic
will ensue.
The setting of the retransmit interval should be conservative, or needless retransmissions will result.
The value should be larger for serial lines and virtual links.
The transmit delay value should take into account the transmission and propagation delays for the
interface.
1384
Specifies an OSPFv3 domain. OSPF-Default is the only one currently
supported.
Specifies the router ID of the other end of the link.
Specifies an OSPFv3 area, a four-byte, dotted decimal number.
Specifies the length of time that the router waits before retransmitting an LSA
that is not acknowledged. The range is 1 - 3,600 seconds.
Specifies the length of time it takes to transmit an LSA packet over the
interface. The range is 0 - 3,600 seconds.
Specifies the interval at which routers send hello packets. The range is 1 -
65,535 seconds.
Specifies the interval after which a neighboring router is declared down due to
the fact that hello packets are no longer received from the neighbor. The range
is 1 - 2,147,483,647 seconds.
