Advertising Bandwidth for Neighbors on a Broadcast Link Support

This feature is supported on all SRX Series and J Series devices.

You can now advertise bandwidth for neighbors on a broadcast link. The network link is a point-to-multipoint (P2MP) link in the OSPFv3 link state database. This feature uses existing OSPF neighbor discovery to provide automatic discovery without configuration. It allows each node to advertise a different metric to every other node in the network to accurately represent the cost of communication. To support this feature, a new interface-type under the OSPFv3 interface configuration has been added to configure the interface as p2mp-over-lan. OSPFv3 then uses LAN procedures for neighbor discovery and flooding, but represents the interface as P2MP in the link state database.

The interface type and router LSA are available under the following hierarchies:

• [protocols ospf3 area area-id interface interface-name]
• [routing-instances routing-instances-name protocols ospf3 area area-id interface interface-name]
