Command Remarks
8. Configure interface
authentication mode.
• Configure simple authentication:
ospf authentication-mode simple { cipher
cipher-string | plain plain-string }
• Configure MD5 authentication:
ospf authentication-mode { hmac-md5 |
md5 } key-id { cipher cipher-string | plain
plain-string }
Use either method.
By default, no interface
authentication is
configured.
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:
Ste

Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Enable the interface to add its
MTU into DD packets.
ospf mtu-enable
By default, the interface adds an
MTU value of 0 into DD packets.
Configuring the maximum number of external LSAs in LSDB

Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id router-id |
vpn-instance vpn-instance-name ] *
N/A
3. Specify the maximum number
of external LSAs in the LSDB.
lsdb-overflow-limit number
By default, the
maximum number of
external LSAs in the
LSDB is not limited.
Configuring 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.
