isis authentication send-only
Use this command to set the send-only option to the interface-related packets.
Use this command before configuring the ISIS authentication mode and ISIS 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.
Use the no parameter with this command to unset the send-only option to the interface-related packets.
