Area ID
An identifier for the transit area the virtual link crosses.
Neighbor
Router ID
The IP address of the OSPF router on this end of the
virtual link.
Transit Delay 1 second
The estimated number of seconds it takes to transmit a
link state update packet over this virtual link.
Range: 0-3600 seconds
Retransmit
Interval
5 seconds
The number of seconds between retransmitting link-state
advertisements to the router at the other end on the
virtual link. This value is also used when retransmitting
database descriptions and link-state request packets.
Range: 0-3600 seconds
Hello Interval² 10 seconds
The interval, in seconds, between sending Hello packets
out the router interface.
Range: 1-65535 seconds
Dead Interval² 40 seconds
The number of seconds that a router’s Hello packets
have not been seen before the router at the other end of
the virtual link is declared down. This should be a
multiple of the Hello interval.
Range: 1-65535 seconds
Authentication
Type
None
Authentication can be used to ensure that routing
information comes from a valid source. The options
include none or a simple password.
Authentication
Key
A simple password must be provided if authentication is
enabled. (An authentication string is case sensitive, and
can be up to 16 characters.)
OSPF Host Route Configuration
A host route is a prefix that will be advertised as a stub network in one of the router’s
link state advertisements. These prefixes may be IP addresses of hosts directly
attached to the router, which themselves do not run OSPF. The router advertises these
addresses by proxy.
