1202 OSPFv3 Commands
User Guidelines
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.
Example
The following example changes the default OSPF network type to point-to-
point.
console(config)#interface vlan 15
console(config-if-vlan15)#ipv6 ospf network point-to-
point
ipv6 ospf priority
Use the ipv6 ospf priority command in Interface Configuration mode to set
the OSPF priority for the specified router interface. Use the no form of the
command to return the priority to the default value.
Syntax
ipv6 ospf priority
number-value
no ipv6 ospf priority
•
number-value
— Specifies the OSPF priority for the specified router
interface. (Range: 0–255) A value of 0 indicates that the router is not
eligible to become the designated router on this network.
Default Configuration
1, the highest router priority, is the default value.
Command Mode
Interface Configuration (VLAN, Tunnel, Loopback) mode.
