IP Routing Features
Configuring OSPF
OSPF Password Authentication on a Virtual Link.
Syntax: area < area-id > virtual-link < ip-addr > authentication-key < octet-string >
no area 1 virtual-link < ip-address > authentication
Used to configure password authentication in the router OSPF
context on both ABRs in a virtual link . The password takes
effect immediately, and all OSPF packets transmitted on the
link contain this password. Every OSPF packet received on the
interface for the virtual link on each ABR is checked for the
password. If it is not present, then the packet is dropped. To
disable password authentication on an ABR interface used for
a virtual link, use the
no form of the command. The password
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-addr >: 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.)
< octet-string >: An alphanumeric string of one to eight
characters. (Spaces are not allowed.) To change the password,
re-execute the command with the new password.
Note: To replace the password method with the MD5 method
on a given interface, overwrite the password configuration by
using the MD5 form of the command shown in the next syntax
description. (It is not necessary to disable the currently
configured OSPF password.)
Default: Disabled
