type. For example, if the network does not support multicasing it can be configured Non-
broadcast type from Broadcast type, and NBMA network as a Frame relay can be
broadcast network type.
NBMA type network need virtual circuit to connect routers. But Point-to-multipoint type
uses virtual circuit on part of network to save the management expenses. It does not to
need to configure Neighbor router to connect routers which are not directly connected. It
also saves IP resources and no need to configure the process for destination router. It
supports those benefits for stable network services.
Generally, the routers and Layer 3 switches are using Broadcast type network.
To select an OSPF network type, use the following command.
ip ospf network {broadcast | non-broadcast |
point-to-multipoint [non-broadcast] | point-to-
point}
Selects an OSPF network type.
11.2.4.10 Disabling OSPF Packet Processing
To disable the OSPF packet processing on the specific interface, use the following
command.
Disables the OSPF packet processing on the specific
interface.
Restores OSPF packet processing on a selected
interface. (default)
11.2.5 Non-Broadcast Network
To operate NBMA type network, neighbor router configuration is needed. And IP address,
Priority, Poll-interval configuration as well. Priority is information for designate router
selection and it configured [0] as a default. Poll-interval is the waiting time to re-get the
hello packet from dead Neighbor router. It configured 120 seconds as a default.
To configure a router communicated by non-broadcast type, use the following command.
neighbor A.B.C.D [cost <1-65535>]
Configures a neighbor router of NBMA
type.
neighbor A.B.C.D priority <0-255>
neighbor A.B.C.D priority <0-255> poll-interval
<1-65535>
neighbor A.B.C.D poll-interval <1-65535>
neighbor A.B.C.D poll-interval <1-65535>
priority <0-255>
