Usage
The
ospf restart helper
command requires at least one parameter, but you may
use more than one in the same command (excluding parameter
never
).
The
no
version of this command turns off the OSPF restart helper, while the
no
ospf restart helper max-grace-period
command resets the max-grace-period,
rather than the helper policy itself.
