Setting A Dr Priority For An Interface; Ignoring Mtu Check For Dd Packets; Disabling Interfaces From Receiving And Sending Ospfv3 Packets - HP FlexFabric 12900E Series Configuration Manual

For a stable network, the minimum interval is used. If network changes become frequent, the LSA
generation interval is incremented by the incremental interval × 2
maximum interval is reached. The value n is the number of generation times.
To set the LSA generation interval:
Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Set
generation interval.

Setting a DR priority for an interface

The router priority is used for DR election. Interfaces having the priority 0 cannot become a DR or
BDR.
To configure a DR priority for an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Set a router priority.

Ignoring MTU check for DD packets

When LSAs are few in DD packets, it is unnecessary to check the MTU in DD packets to improve
efficiency.
To ignore MTU check for DD packets:
Step
1. Enter system view.
2. Enter interface view.
3. Ignore MTU check for DD
packets.
Disabling interfaces from receiving and sending OSPFv3
packets
After an OSPFv3 interface is set to silent, direct routes of the interface can still be advertised in
Intra-Area-Prefix LSAs through other interfaces, but other OSPFv3 packets cannot be advertised.
No neighboring relationship can be established on the interface. This feature can enhance the
adaptability of OSPFv3 networking.
