5.3.2 Configuring Network Types for OSPF Interfaces
OSPF classifies networks into four types based on the types of link layer protocols. You can
configure the network type for an OSPF interface to forcibly change its original network type.
Context
By default, the physical interface type determines the network type.
l
The network type of an Ethernet interface is Broadcast.
l
The network type of a serial interface or a POS interface running PPP or HDLC is P2P.
l
The network type of an ATM interface or a Frame Relay (FR) interface is NBMA.
NOTE
A P2MP network is forcibly changed from another other type of network.
The network types of the interfaces on both ends of a link must be the same; otherwise, the OSPF
neighbor relationship cannot be established. Only when the network type of one OSPF interface
is broadcast and the network type of the other OSPF interface is P2P, the two interfaces can still
set up the neighbor relationship; but cannot learn the OSPF routing information each other.
Procedure
Step 1
Run:
system-view
The system view is displayed.
Step 2
Run:
interface
interface-type
interface-number
The interface view is displayed.
Step 3
Run:
ospf network-type
{
broadcast
|
nbma
|
p2mp
|
p2p
[
peer-ip-ignore
] }
The network type of the OSPF interface is configured.
When the network type is configured for an interface, the original network type of the interface
is replaced.
The network type can be configured based on the real world situations.
l
On an interface with the broadcast network type, if a router that does not support the multicast
address exists, change the network type of the interface to NBMA.
