ospf mtu-enable

Syntax
ospf mtu-enable
undo ospf mtu-enable
View
Interface view
Default level
2: System level
Parameters
None
Description
Use the ospf mtu-enable command to enable an interface to add the real MTU into DD packets.
Use the undo ospf mtu-enable command 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 Virtual-Template or 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.
This configuration is not supported on the null interface.
•
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
