Ospf Network Type Configuration - Huawei Quidway S5600 Series Operation Manual

Operation Manual – Routing Protocol
Quidway S5600 Series Ethernet Switches-Release 1510
Note:
You must use the stub command on all the routers connected to a stub area to
configure the area with the stub attribute.
You must use the nssa command on all the routers connected to an NSSA area to
configure the area with the NSSA attribute.

4.5 OSPF Network Type Configuration

OSPF divides networks into four types by link layer protocol. See section 4.1.4 "OSPF
Network Type". An NBMA network must be fully connected. That is, any two routers in
the network must be directly reachable to each other through a virtual circuit. However,
in many cases, this cannot be implemented and you need to use a command to change
the network type forcibly.
Configure the interface type as P2MP if not all the routers are directly accessible on an
NBMA network. Change the interface type to P2P if the router has only one peer on the
NBMA network.
In addition, when configuring a broadcast network or NBMA network, you can also
specify DR priority for each interface to control the DR/BDR selection in the network.
Thus, the router with higher performance and reliability can be selected as a DR or
BDR.
4.5.1 Configuration Prerequisites
Before configuring the network type of an OSPF interface, perform the following tasks:
Configuring the network layer address of the interface so that the adjacent node is
reachable at network layer
Performing basic OSPF configuration
