DGS-3610 Series Configuration Guide Chapter 28 OSPF Routing Protocol Configuration
Figure 28-2 Example of Configuring the OSPF Point-to-Multipoint Network Type
Requirements: 1) The point-to-multipoint network should be configured among devices A, B,
and C.

Concrete Configuration of Devices
If the interface is configured with the point-to-multipoint network type, the point-to-multipoint
network type does not have the process to elect the specified router. The OSPF operation
has similar action as the point-to-multipoint network type.
Configuration of Device A:
#Configuring Ethernet interface
interface FastEthernet 0/0
ip address 192.168.12.1 255.255.255.0
#Configure the WAN port
interface Serial 1/0
ip address 192.168.123.1 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint
router ospf 1
network 192.168.23.0 0.0.0.255 area 0
network 192.168.123.0 0.0.0.255 area 0
Configuration of Device B:
#Configuring Ethernet interface
interface FastEthernet 0/0
ip address 192.168.23.2 255.255.255.0
#Configure the WAN port
interface Serial 1/0
