Configuring An Nbma/P2Mp Neighbor - 3Com 5500-EI PWR Install Manual

To do...
Enter interface view
Configure the network
type of the OSPF
interface
After an interface has been configured with a new network type, the original network type of the
interface is removed automatically.
An adjacency can be established between two interfaces configured as broadcast, NBMA, or
P2MP only if the interfaces are on the same network segment.
If the network type of an interface is NBMA or is changed to NBMA, you must use the peer
command to specify the peer.
If the network type of an interface is P2MP and the unicast keyword is specified, an interface
sends packets in the unicast mode. In this case, you must use the peer command to specify the
peer.

Configuring an NBMA/P2MP Neighbor

When the network type of an interface on the router is one of the following types, you need to specify the
IP address of the neighbor router:
NBMA
P2MP ( required only when the interface sends packets in the unicast mode)
Since the neighbor routers cannot be discovered by broadcasting Hello packets, you must manually
specify the IP address of the neighbor router. For an NBMA network, you can determine whether the
neighbor has the DR election right.
Follow these steps to configure NBMA/P2MP neighbor:
To do...
Enter system view
Enter OSPF view
Configure an NBMA/P2MP
neighbor
Use the command...
interface interface-type
interface-number
ospf network-type
{ broadcast | nbma | p2mp
[ unicast ] | p2p }
Use the command...
system-view
ospf [ process-id [ router-id
router-id ] ]
peer ip-address [ dr-priority
dr-priority ]
4-17
Remarks
—
Required
By default, the network type of an
interface depends on the physical
interface.

By default, the priority for the
neighbor of an NBMA interface
is 1.
