Adding The Interface Mtu Into Dd Packets; Setting The Dscp Value For Outgoing Ospf Packets; Setting The Maximum Number Of External Lsas In Lsdb; Setting Ospf Exit Overflow Interval - HP FlexFabric 12900E Series Configuration Manual

Adding the interface MTU into DD packets

By default, an OSPF interface adds a value of 0 into the interface MTU field of a DD packet rather
than the actual interface MTU. You can enable an interface to add its MTU into DD packets.
To add the interface MTU into DD packets:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the interface to add
its MTU into DD packets.

Setting the DSCP value for outgoing OSPF packets

The DSCP value specifies the precedence of outgoing packets.
To set the DSCP value for OSPF packets:
Step
1. Enter system view.
2. Enter OSPF view.
3. Set the DSCP value for
outgoing OSPF packets.

Setting the maximum number of external LSAs in LSDB

Step
1. Enter system view.
2. Enter OSPF view.
3. Set the maximum number of
external LSAs in the LSDB.

Setting OSPF exit overflow interval

When the number of LSAs in the LSDB exceeds the upper limit, the LSDB is in an overflow state. To
save resources, OSPF does not receive any external LSAs and deletes the external LSAs generated
by itself when in this state.
Perform this task to configure the interval that OSPF exits overflow state.
To set the OSPF exit overflow interval:
