Keywords and
variables

Description

Default Availability

authentication
{md5 | none |
text}

Set the authentication type.
Use the authentication keyword

to define the authentication used for

OSPF packets sent and received

over this virtual link. If you select

none, no authentication is used. If

you select text, the authentication

key is sent as plain text. If you select

md5, an authentication key is used to

generate an MD5 hash.
Both text mode and MD5 mode only

guarantee the authenticity of the

OSPF packet, not the confidentiality

of the information in the packet.
In text mode the key is sent in clear

text over the network. Text mode is

usually used only to prevent network

problems that can occur if an

unwanted or misconfigured router is

mistakenly added to the area.
