Use the undo silent-interface
An interface is able to send OSPFv3 packets by default.
Multiple processes can disable the same interface from sending OSPFv3 packets,
but use of the silent-interface command takes effect only on interfaces enabled
with the current process.
# Disable an interface from sending OSPFv3 packets in OSPFv3 processes 100 and
200.

delay-interval: The interval in seconds between when OSPFv3 receives a topology
change and when it starts SPF calculation. in the range 1 to 65535.
hold-interval: The hold interval in seconds between two SPF calculations, in the

The delay interval and hold interval default to 5s and 10s.
An OSPFv3 router works out a shortest path tree with itself as root based on the
LSDB, and decides on the next hop to a destination network according the tree.
Adjusting the SPF calculation interval can restrain bandwidth and router resource
from over consumption due to frequent network changes.
# Configure the delay interval and hold interval as 6 seconds for SPF calculation.
