Use the authenticate command to configure the authentication string for the PGP message exchange between
the protect and working routers. Use the no form of this command to revert to the default authentication string.
The authenticate command applies only in multirouter automatic protection switching (APS) group
configurations.
In multirouter APS topologies, the protect and working routers communicate with each other through the User
Datagram Protocol (UDP)-based Pretty Good Privacy protocol. Each Pretty Good Privacy packet contains an
authentication string used for packet validation. The authentication string on all routers involved in the same
APS group operation must match for proper APS operation.
