To configure the maximum time drift for the MD5 authentication key of an interface, use the set protocols ospf4 area interface vif address authentication md5 max-time-drift command in L2/L3 configuration mode.

Command Syntax

set protocols ospf4 vrf vrf-name area area-id interface interface-name vif vif-name address ip-address authentication md5 key-id max-time-drift time



Optional. Specifies a VRF name. The value is a string. It’s a user-defined VRF set by the command set ip vrf <vrf-name> [description <string>].

area-idOSPF area identifier.
interface-nameInterface name.
vif-nameVirtual interface name.
ip-addressVirtual interface IP address, used for OSPF.
key-idMD5 authentication key identifier. The range is 0-255.
timeThe maximum time drift among all routers, in seconds. The range is 0-65535. For maximum time drift, use 65535.


This example configure the maximum time drift of the OSPF interface MD5 authentication as 20 seconds.
