See JunosE IP Services Configuration Guide, for information about configuring route maps.
You can configure OSPF nonbroadcast multiaccess (NBMA) networks. You can configure
your OSPF network type as NBMA, regardless of the default medium. This configuration
is useful when, for example, you have routers in your network that do not support multicast
addressing.
You must use the neighbor command to specify the router's OSPF neighbors.
To configure OSPF for an NBMA network:
Configure an interface network type as NBMA for OSPF.
1.
host1(config-subif)#ip ospf network non-broadcast
Exit Interface Configuration mode. Enter Global Configuration mode.
2.
host1(config-subif)#exit
Configure an OSPF routing process, and enter Router Configuration mode.
3.
host1(config)#router ospf 5
Specify an OSPF neighbor, and optionally assign a priority number or poll interval to
4.
the neighbor.
host1(config-router)#neighbor 10.12.14.1 priority 5 poll-interval 180
Repeat Step 4 for each neighbor in the OSPF network.
5.
If you want to configure the network type for a specific interface or OSPF area, rather
than for all OSPF interfaces, you can use the address network command rather than the
ip ospf network command.
Use to configure the network type on a specific OSPF interface or for a specific OSPF
area to a type other than the default for the medium.
You must first issue the address area command before issuing the address network
command.
Example
host1(config-router)#address 10.12.10.2 network broadcast
Use the no version to restore the default value for the medium.
See address network
Use to configure the network type on all OSPF interfaces on the OSPF network to a
type other than the default for the medium.
