R0106-HP MSR Router Series Layer 3 - IP Routing Command Reference(V7)

547
Usage guidelines
If a router on a broadcast network does not support multicast, configure the network type for the
connected interfaces as NBMA.
If any two routers on an NBMA network are directly connected through a virtual link, the network is fully
meshed. You can configure the network type for the connected interfaces as NBMA. If two routers are not
directly connected, configure the P2MP network type so that the two routers can exchange routing
information through another router.
When the network type of an interface is NBMA or P2MP unicast, you must use the peer command to
specify the neighbor.
When the network type of an interface is P2MP unicast, all OSPFv3 packets are unicast by the interface.
Examples
# Configure the OSPFv3 network type for GigabitEthernet 2/1/1 as NBMA.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] ospfv3 network-type nbma
Related commands
ospfv3 dr-priority
ospfv3 peer
Use ospfv3 peer to specify a neighbor and the DR priority of the neighbor.
Use undo ospfv3 peer to remove the configuration.
Syntax
ospfv3 peer ipv6-address [ cost value | dr-priority dr-priority ] [ instance instance-id ]
undo ospfv3 peer ipv6-address [ instance instance-id ]
Default
No link-local address is specified for the neighbor interface.
Views
Interface view
Predefined user roles
network-admin
Parameters
ipv6-address: Specifies the link-local IPv6 address of the neighbor.
cost value: Specifies the cost of the neighbor, in the range of 1 to 65535.
dr-priority dr-priority: Specifies the DR priority of the neighbor, in the range of 0 to 255. The default is 1.
Instance instance-id: Specifies an interface by its ID in the range of 0 to 255. The default is 0.
Usage guidelines
For NBMA and P2MP interfaces (only when in unicast mode), you must specify the link-local IPv6
addresses of their neighbors because these interfaces cannot find neighbors through broadcasting hello
packets. For NBMA interfaces, you can also specify DR priorities for their neighbors.
