OSPF Commands

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.
