Configures the ESRP (Extreme Standby Router Protocol) neighbor timeout value.
| esrpDomain | Specifies an ESRP domain name. |
| seconds | Specifies the number of seconds after which an ESRP neighbor times out. The range is 6 to 1024 seconds. |
The default neighbor timeout is 8 seconds (four times the hello timer).
The neighbor timeout specifies the amount of time that ESRP waits before considering the neighbor down. The neighbor value must be at least 3 times the hello timer value. Entering a value outside of that range generates an error message similar to the following:
operation Failed. Valid timer relationship "neighbor timeout >= 3*hello ; neutral timeout >= 2*hello ; premaster timeout >= 3*hello"!The seconds range is 3*hello to 1024 seconds.
To view the neighbor timer settings, use the show esrp { {name} | {type [vpls-redundancy | standard]} } command.

The following command configures the ESRP neighbor timeout to 14 seconds for the ESRP domain esrp1:
configure esrp esrp1 timer neighbor 14
