Two-hop forwarding
There are two ways that a BBMD may distribute broadcast
messages to remote IP subnetworks: One-hop or two-hop
distribution.
For one-hop forwarding, see the description in this table.
All IP routers are not configured to pass directed broadcasts.
Therefore BBMD may be configured to send a directed message
to the BBMD on the remote subnetwork (two-hop distribution)
which then transmits it using the B/IP broadcast address.
For more information on two-hop forwarding or two-hop
distribution, see section
Global Options, Two-hop forwarding
in
chapter
.
UDP
User Datagram Protocol uses the Internet Protocol as the
underlying protocol. It enables programs running on different
computers on a network to communicate by sending short
messages known as datagrams to each other.
