| Description | vRtrIsisIfLevelHelloAuthKey is the authentication key string used
to verify the authenticity of packets sent by neighboring routers
on this IS-IS interface at this level. For authentication to
succeed both the authentication key and the authentication type
defined by the vRtrIsisIfLevelHelloAuthType variable must match.
If vRtrIsisIfLevelHelloAuthType is set to 'password',
vRtrIsisIfLevelHelloAuthKey can include any ASCII character.
Authentication can be configured globally and applied to all
ISIS levels or it can be configured on a per level basis.
The most specific value is used. If the value of
vRtrIsisIfLevelHelloAuthType is 'useGlobal', then the global
values, if any, defined in vRtrIsisIfHelloAuthKey and
vRtrIsisIfHelloAuthType are used instead.
When read, vRtrIsisIfLevelHelloAuthKey always returns an Octet
String of length zero. |
