OSPF COMMANDS
AREA
VIRTUAL-LINK
Mode Router Configuration
Usage You can configure virtual links between any two backbone routers that have an
interface to a common non-backbone area. The protocol treats these two routers,
joined by a virtual link, as if they were connected by an unnumbered
point-to-point network. To configure a virtual link, you require:
The transit area ID, i.e. the area ID of the non backbone area that the two
backbone routers are both connected to.
The corresponding virtual link neighbor’s router ID. To see the router ID use
the show ip ospf command.
Configure the hello-interval to be the same for all routers attached to a common
network. A short hello-interval results in the router detecting topological changes
faster but also an increase in the routing traffic.
The retransmit-interval is the expected round-trip delay between any two
routers in a network. Set the value to be greater than the expected round-trip delay
to avoid needless retransmissions.
The transmit-delay is the time taken to transmit a link state update packet on the
interface. Before transmission, the link state advertisements in the update packet,
are incremented by this amount. Set the transmit-delay to be greater than zero.
Also, take into account the transmission and propagation delays for the interface.
Example
awplus# configure terminal
awplus(config)# router ospf 100
awplus(config-router)# area 1 virtual-link 10.10.11.50 hello 5
dead 10
message-digest Use message-digest authentication.
null Use null authentication to override password or message
digest.
dead-interval If no packets are received from a particular neighbor for
dead-interval seconds, the router considers that neighboring
router as being off-line.
Default: 40 seconds
<1-65535> The number of seconds in the interval.
hello-interval The interval the router waits before it sends a hello packet.
Default: 10 seconds
<1-65535> The number of seconds in the interval.
retransmit-
interval
The interval the router waits before it retransmits a packet.
Default: 5 seconds
<1-3600> The number of seconds in the interval.
transmit-delay The interval the router waits before it transmits a packet.
Default: 1 seconds
<1-3600> The number of seconds in the interval.
