ospf network-type p2p peer-ip-ignore

Function

The ospf network-type p2p peer-ip-ignore command sets the network type for an OSPF interface.

By default, the network type of an interface is determined by the physical interface.

Format

ospf network-type p2p peer-ip-ignore

Parameters

Parameter	Description	Value
p2p	Indicates that the network type of the interface is changed to point-to-point.	-
peer-ip-ignore	Disables network segment check when IP address unnumbering is not configured for a P2P interface changed from a broadcast interface and the interface tries to establish an OSPF neighbor relationship. By default, if peer-ip-ignore is not specified in the command, OSPF checks the network segment of the two ends during which an OSPF neighbor relationship is to be established. Specifically, OSPF performs an AND operation on the local subnet mask and the local IP address and on the local subnet mask and the remote IP address. An OSPF neighbor relationship can be established only when the results on the two ends are the same.	-

Parameter

Description

Value

p2p

Indicates that the network type of the interface is changed to point-to-point.

peer-ip-ignore

Disables network segment check when IP address unnumbering is not configured for a P2P interface changed from a broadcast interface and the interface tries to establish an OSPF neighbor relationship. By default, if peer-ip-ignore is not specified in the command, OSPF checks the network segment of the two ends during which an OSPF neighbor relationship is to be established. Specifically, OSPF performs an AND operation on the local subnet mask and the local IP address and on the local subnet mask and the remote IP address. An OSPF neighbor relationship can be established only when the results on the two ends are the same.

Usage Guidelines

Usage Scenario

When link layer protocols remain unchanged, you can change network types and configure OSPF features to flexibly build networks.

If there are only two devices that run OSPF in the same network segment, the network type of an interface can be changed to P2P.

Precautions

Generally, the network types of two OSPF interfaces on the both ends of the link must be identical. Otherwise, the two interfaces cannot set up a neighbor relationship.

Example

# Set network type of GigabitEthernet 0/1/0 to point-to-point type.
