Any host connected to such network type can communicate with any other host usign broadcast capabilities of the network. This is a default network type for Ehternet-based interfaces. – Tunnel interfaces (point-to-point GRE encapsulation). This network type used on following interface types:
– point-to-multipoint – broadcast or non-broadcast – multi-access – broadcast or non-broadcast There are three major network types in OSPF: So, an ability to deliver broadcast/multicast traffic is a capability of a network. If do not remember how broadcast and multicast frame are processed, please refer to Broadcast/Ethernet networks.Īs a reminder: every broadcast or multicast frame must be flooded – a network will replicate this frame and send it to every host in this broadcast domain. The simplest example of a broadcast multi-access segment is Ethernet.
Why you should avoid normal/regular OSPF areasīroadcast capabilities are needed only when there are more than two device on a segment and you need them to be able to discover each other.
