| Description | vRtrIsisLevelAuthKey is the authentication key string used to
verify the authenticity of packets sent by neighboring routers on
an IS-IS interface at this level. For authentication to succeed
both the authentication key and the authentication type defined
by the vRtrIsisLevelAuthType variable must match. If
vRtrIsisLevelAuthType is set to 'password', vRtrIsisLevelAuthKey
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
vRtrIsisLevelAuthType is 'useGlobal', then the global
values, if any, defined in vRtrIsisAuthKey and vRtrIsisAuthType
are used instead.
When read, vRtrIsisLevelAuthKey always returns an Octet String of
length zero. |
