ospf mtu-enable

Syntax
ospf mtu-enable
undo ospf mtu-enable
View
Interface view
Parameters
None
Description
Use the ospf mtu-enable command to add the interface MTU to the MTU field in DD packets.
Use the undo ospf mtu-enable command to restore the default.
By default, the MTU field in DD packets is 0. That is, no interface MTU is added to the MTU field in DD
packets.
The default MTU value in DD packet is 0. You can use this command to add the interface MTU to the
MTU field in DD packets.
When a router starts, it sends a Hello packet via the OSPF interface, and the router that receives the
hello packet checks parameters carried in the packet. If parameters of the two routers match, they
become neighbors.
Not every pair of neighboring routers become adjacent, which depends on network types. Only by
synchronizing the LSDB via exchanging DD packets and LSAs can two routers become adjacent. If the
MTU values of the DD packets sent by two neighboring routers are different, they will not receive DD
packets from each other and therefore they will not become adjacent.
Examples
# Add the MTU of the interface VLAN-interface 3 to the MTU field in DD packets.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] interface Vlan-interface 3
