Example: Configuring the OSPF multi-process feature

Network configuration

As shown in Figure 1, Device A and Device B establish a neighbor relationship in OSPF process 100, and Device B and Device C establish a neighbor relationship in OSPF process 200. Device A and Device C cannot learn routes from each other through OSPF.

Procedures

Configuring Device A

# Specify DeviceA as the device name.

<Sysname> system-view

[Sysname] sysname DeviceA

# Enable OSPF process 100 and specify the interface whose primary IP address is on network 172.10.1.0/24 to run OSPF.

[DeviceA] ospf 100 router-id 1.1.1.9

[DeviceA-ospf-100] area 0.0.0.0

[DeviceA-ospf-100-area-0.0.0.0] quit

[DeviceA-ospf-100] quit

Configuring Device B

# Specify DeviceB as the device name.

<Sysname> system-view

[Sysname] sysname DeviceB

# Enable OSPF process 100 and specify the interface whose primary IP address is on network 172.10.1.0/24 to run OSPF.

[DeviceB] ospf 100 router-id 2.2.2.9

[DeviceB-ospf-100-area-0.0.0.0] quit

[DeviceB-ospf-100] quit

# Enable OSPF process 200 and specify the interface whose primary IP address is on network 131.108.1.0/24 to run OSPF.

[DeviceB] ospf 200 router-id 2.2.2.9

[DeviceB-ospf-200-area-0.0.0.0] quit

[DeviceB-ospf-200] quit

Configuring Device C

# Specify DeviceC as the device name.

<Sysname> system-view

[Sysname] sysname DeviceC

# Enable OSPF process 200 and specify the interface whose primary IP address is on network 131.108.1.0/24 to run OSPF.

[DeviceC] ospf 200 router-id 3.3.3.9

[DeviceC-ospf-200] area 0.0.0.0

[DeviceC-ospf-200-area-0.0.0.0] network 131.108.1.0 0.0.0.255

[DeviceC-ospf-200-area-0.0.0.0] quit

[DeviceC-ospf-200] quit

Verifying the configuration

# Execute the display ospf peer command on Device B to verify that Device A and Device C have already established a neighbor relationship.

[DeviceB] display ospf peer
