The value of vRtrIfDelaySeconds specifies the time in seconds
that is used to bring up the interface.
When interface comes up, it will not become operational until
after the specified delay.
When used to configure delayed-enable for a router interface, the
values specified for vRtrIfDelaySeconds can be in the range of
0..1200. When used to configure hold-time of a Multi-homing secondary
interface, the values specified can be in the range of 0..65535.
The default value of vRtrIfDelaySeconds is also based on the router
interface type. When used for a regular interface its default value is
0. When used for a Multi-homing secondary interface, its default value
is 30.
