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 ipv6 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 To configure a virtual link through area 1to the router with router-ID 10.10.11.50,
use the following commands:
awplus# configure terminal
awplus(config)# router ipv6 ospf 100
awplus(config-router)# area 1 virtual-link 10.10.11.50 hello 5
dead 10
