Default command level
2: System level
Parameters
delay-interval: Specifies the interval in seconds between when OSPFv3 receives a topology change and
when it starts SPF calculation. The value range is 0 to 65535.
hold-interval: Specifies the hold interval in seconds between two consecutive SPF calculations, in the
range of 0 to 65535.
Usage guidelines
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.
Setting both the delay-interval and hold-interval to 0 triggers an SPF calculation at once, improving the
network convergence speed.
Examples
# Configure the delay interval and hold interval as 6 seconds for SPF calculation.

Parameters
no-summary: This argument is only applicable to the ABR of a stub area. With this keyword configured,
the ABR advertises only a default route in an Inter-Area-Prefix-LSA into the stub area. No AS-external-LSA,
Inter-Area-Router-LSA, or other Inter-Area-Prefix-LSA is advertised in the area. The stub area of this kind is
also known as a "totally stub area."
