Ignoring Mtu Check For Dd Packets; Disabling Interfaces From Receiving And Sending Ospfv3 Packets; Enabling The Logging Of Neighbor State Changes - HP MSR2000 series Configuration Manual

Step
3. Configure a DR 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
Follow these guidelines when you disable interfaces from receiving and sending OSPF packets:
Multiple OSPFv3 processes can disable the same interface from receiving and sending OSPFv3
•
packets. Using the silent-interface command disables only the interfaces associated with the current
process.
After an OSPF interface is set to silent, direct routes of the interface can still be advertised in
•
Intra-Area-Prefix-LSAs via 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.
To disable interfaces from receiving and sending OSPFv3 packets:
Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Disable interfaces from
receiving and sending
OSPFv3 packets.

Remarks
Optional.
By default, the DR priority is 1.
The DR priority of an interface
determines the interface's
qualification in DR election.
Interfaces having the priority 0
cannot become a DR or BDR.
