956 OSPFv3 Commands
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.
Syntax
ipv6 ospf mtu-ignore
no ipv6 ospf mtu-ignore
Default Configuration
Enabled is the default state.
Command Mode
Interface Configuration (VLAN, Tunnel, Loopback) mode.
User Guidelines
This command has no user guidelines.
Example
The following example disables OSPF maximum transmission unit (MTU)
mismatch detection.
console(config)#interface vlan 15
console(config-if-vlan15)#ipv6 ospf mtu-ignore
ipv6 ospf network
Use the ipv6 ospf network command in Interface Configuration mode to
change the default OSPF network type for the interface. Normally, the
network type is determined from the physical IP network type. By default all
Ethernet networks are OSPF-type broadcast. Similarly, tunnel interfaces
default to point-to-point. When an Ethernet port is used as a single large
bandwidth IP network between two routers, the network type can be point-to-
point since there are only two routers. Using point-to-point as the network
type eliminates the overhead of the OSPF designated router election. It is
normally not useful to set a tunnel to OSPF network type broadcast.
