authentication send-only
Use this command to set the send-only option at the instance level.
Use this command before configuring the authentication mode and authentication key-chain, so that the implementation of authentication goes smoothly. That is, the routers will have more time for the keys to be configured on each router if authentication is inserted only on the packets being sent, not checked on packets being received. After all routers that must communicate are configured with this command, enable the authentication mode and key chain on each router. Then, specify the no authentication send-only command to disable the send-only feature.
If the level-1-2 keyword is configured, the send-only feature applies to both levels.
Use the no parameter with this command to unset the send-only option.
