OSPF Commands 883
Default Configuration
10 is the default number of seconds.
Command Mode
Interface Configuration (VLAN) mode.
User Guidelines
The value for the length of time must be the same for all routers attached to a
network.
Example
The following example sets the OSPF hello interval at 30 seconds.
console(config-if-vlan15)#ip ospf hello-interval 30
ip ospf mtu-ignore
Use the ip ospf mtu-ignore command in Interface Configuration mode to
disable OSPF maximum transmission unit (MTU) mismatch detection.
OSPF Database Description packets specify the size of the largest IP packet
that can be sent without fragmentation on the interface. When a router
receives a Database Description packet, it examines the MTU advertised by
the neighbor. By default, if the MTU is larger than the router can accept, the
Database Description packet is rejected and the OSPF adjacency is not
established. Use the no form of the command to enable OSPF maximum
transmission unit (MTU) mismatch detection.
