Is your feature request related to a problem? Please describe.
We have a lot of OSPF information in our network with some unstable connections. Graceful restart would help us stabilize the network.
Describe the solution you'd like
A checkbox to enable or disable graceful restart and a number input with the grace period (default 120s, 1-1800s).
Describe alternatives you've considered
None
