Usage guidelines
ENDP uses an ENDS probe timer and a registration aging timer in addition to the ENDC register timer set with this command.
ENDS probe timer—Sets the interval for an ENDC to detect an ENDS. This timer is maintained on ENDCs and is not user configurable.
ENDC register timer—Sets the interval for an ENDC to update its registration with an ENDS. This timer is by default 15 seconds and can be changed with the evi neighbor-discovery client register-interval command on ENDCs.
Registration aging timer—This timer is five times the ENDC register timer. This timer is maintained on ENDSs. When the registration aging timer for an ENDC expires, ENDS removes the ENDC from its ENDC database.
When an ENDC sends a register request to join the EVI network, a 5-second ENDS probe timer starts. The ENDC sends a register request to the ENDS every 5 seconds until it receives a response from the ENDS.
When the ENDC receives a response from the ENDS, the ENDS probe timer stops and an ENDC register timer starts. The ENDC regularly sends register updates at the interval set by the register timer.
If the ENDC does not receive a response after sending five consecutive register packets, the ENDC clears its neighbor information database and starts the ENDS probe timer.
The ENDC adds the register timer setting to each register packet. The ENDS records this timer setting when it adds the ENDC to the ENDC database. If no register update is received from the ENDC before five times the timer is reached, ENDS removes the ENDC from the EVI network.
Examples
# Set the ENDC registration update interval to 30 seconds on the EVI tunnel interface Tunnel 0.
