IP Routing Features
Configuring OSPF
Transit-Delay on a Virtual Link.
Syntax: area < area-id > virtual link < ip-address > transit-delay < 0 - 3600 >
Used in the router OSPF context on both ABRs in a virtual link
to change the estimated number of seconds it takes to transmit
a link state update packet over a virtual link.The transit-delay
setting must be the same on both ABRs on a given virtual link.
< area-id >: Specifies the OSPF area in which both ABRs in a
given virtual link operate. In this use, the area ID is sometimes
termed “transit area ID”. This value must be the same for both
ABRs in the virtual link.
< ip-address >: For an ABR in a given virtual link, this is the
IP address used to create the link on that ABR. (This IP address
matches the IP address of the interface on the opposite end of
the virtual link. Refer to the description of < ip-address > in the
syntax description under “Configuring a Virtual Link” on
page 5-83.)
Use show ip ospf virtual-link < ip-address > to view the current
setting. (Refer to the example on page 5-106.)
Default: 1 second; Range: 1 - 3600 seconds
Example. To change the hello-interval on the virtual link configured for the
network in figure 5-24 on page 5-84 to 60 seconds:
■ On routing switch “A” (IP address 10.0.0.1) you would use the following
command to reconfigure the current hello-interval to 60 seconds:
ProCurve(ospf)# area 1 virtual-link 209.157.22.1
hello-interval 60
■ On routing switch “C” (IP address 209.157.22.1) you would use the
following command to reconfigure the current hello-interval to 60
seconds
ProCurve(ospf)# area 1 virtual-link 10.0.0.1
hello-interval 60
