z 

Both ends of a virtual link are ABRs that must be configured with the vlink-peer command. 

z 

Do not configure virtual links in the areas of a GR-capable process.  

 

OSPFv3 classifies networks into four types upon the link layer protocol: 

By default, the default OSPFv3 interface network types vary with the link layer protocols of the 

interfaces:  

z 

When the link layer protocol is PPP, OSPFv3 considers the network type as P2P by default. 

z 

When the link layer protocol is Ethernet, OSPFv3 considers the network type as broadcast by 

default. 

You can change the network type of an OSPFv3 interface as needed. For example: 

z 

An NBMA network must be fully connected. That is, any two routers in the network must be directly 

reachable to each other through a virtual circuit. In the event no such direct link is available, you 

need to change the network type through a command. 

z 

If direct connections are not available between some routers in an NBMA network, the type of 

interfaces associated should be configured as P2MP, or as P2P for interfaces with only one 

neighbor. 

Before configuring OSPFv3 network types, you have configured: 

z 

IPv6 functions 

z 

OSPFv3 basic functions 

Follow these steps to configure the OSPFv3 network type for an interface: 

Enter system view 

— 

Enter interface view 

interface interface-type 
interface-number 

— 

Configure a network type for 
the OSPFv3 interface 

ospfv3 network-type 
{ broadcast | nbma | p2mp 
[ non-broadcast ] | p2p } 
[ instance instance-id ] 

Optional 

The network type of an interface 
depends on the media type of the 
interface.
