Usage: set virtif [transareaid=][virtnbrid=][transdelay=][retrans=][hello=][dead=][password=]
transareaid - The IP address of the transit area
virtnbrid - The router ID of the virtual neighbor.
transdelay - The estimated number of seconds it takes to transmit a
link state update packet over this interface. This
value should take into account the transmission and
propagation delays of the interface and network media.
The default setting is 1 second.
retrans - The number of seconds between link state advertisement
retransmissions for adjacencies belonging to this
interface. This value should exceed the expected
round-trip delay between any two routers on the attached
network. However, if this value is not conservative,
needless retransmissions result. The value needs to be
larger on low-speed serial lines. A sample value for a
local area network is 5 seconds.
hello - The interval in seconds between transmissions of hello
packets by the router on the interface. You can also
click the arrows to select a new setting. This setting
must be the same for all routers that are attached to a
common network. The shorter the hello interval, the
faster topological changes are detected. However, a
shorter interval also results in more OSPF traffic. A
sample value for an X.25 network is 30 seconds. A sample
value for a local area network is 10 seconds.
dead - The number of seconds before a neighboring router
considers this router to be down. The router is
determined to be down if a neighboring router does not
receive a hello packet sent by this router within the
specified interval. For example, if your hello interval
setting is 15 seconds and your dead interval is 60
seconds, after sending four hello packets and receiving
no acknowledgment or response, neighboring routers
declare that this router is down. This setting should
be an integral multiple of the hello interval
(commonly 4). This value must be the same for all OSPF
router interfaces attached to a common network segment.
password - If passwords are enabled for the area (the default
setting) the password used for this interface by using
any combination of uppercase or lowercase letters or
All interfaces in the same area that are on the same
network must use identical passwords.
Interfaces in the same area that are on different
networks can have different passwords.
By default, passwords are enabled and the password is
12345678. Passwords are transmitted in plaintext, so
this option is for identification, not security. If this
option is unavailable, you must enable passwords for the
