Ospf Network-Type - HP 6125G Command Reference Manual

Default level
2: System level
Parameters
None
Description
Use ospf mtu-enable to enable an interface to add the real MTU into DD packets.
Use undo ospf mtu-enable to restore the default.
By default, an interface adds a MTU of 0 into DD packets, which means no real MTU is added.
After a virtual link is established via a Tunnel, two devices on the link from different vendors may
•
have different MTU values. To make them consistent, set the attached interfaces' default MTU to 0.
• After this command is configured, upon receiving a DD packet, the interface checks whether the
MTU in the packet is greater than its own MTU; if yes, the interface discards the packet.
Examples
# Enable the interface to add the real MTU value into DD packets.
<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] ospf mtu-enable

Description
Use ospf network-type to set the network type for an interface.
Use undo ospf network-type to restore the default network type for an interface.
