IP Routing Features
Configuring OSPF

Retransmit Interval on a Virtual Link.

Syntax: area < area-id > virtual link < ip-address > retransmit-interval < 1 - 3600 >

Used in the router OSPF context on both ABRs in a virtual link
to change the number of seconds between link-state
advertisement (LSA) retransmissions on the virtual link. The
default is 5 seconds. The

retransmit-interval setting must be the

same on both ABRs on a given virtual link. This value is also
used when retransmitting database description and link-state
request packets.
< 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 5-89.)

Use

show ip ospf virtual-link < ip-address > to view the current

setting. (Refer to the example on page 5-116.)

Default: 5 seconds; Range: 1 - 3600 seconds

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 5-89.)

Use

show ip ospf virtual-link < ip-address > to view the current

setting. (Refer to the example on page 5-116.)

Default: 1 second; Range: 1 - 3600 seconds
