Rendezvous Point
-
Auto RP Mode
—Configure automatic Rendezvous Point (RP) announcement and discovery.
You can configure a mode-dynamic way of assigning RPs in a multicast network by means of
auto-RP. When you configure auto-RP for a router, the router learns the address of the RP in
the network automatically. Auto-RP operates in PIM version 1 and version 2.
NOTE:
If the router receives auto-RP announcements split across multiple messages, the router loses the
information in the previous part of the message as soon as the next part of the message is received.
Options include
announce–Listen only for mapping packets. Also configures the router to advertise itself if it
is an RP.
discovery–Listen only for mapping packets.
mapping–Router announce, listens for and generates mapping packets, and announces that
the router is eligible to be an RP.
Mapping Agent
and
No Mapping Agent
checkboxes also appear in this portion of the screen.
Auto-RP specifications state that mapping agents should not send mapping messages if they
receive messages from a mapping agent with a higher IP address. This process is called
mapping agent election. However, some vendors' mapping agents continue to announce
mappings, even in the presence of higher-addressed mapping agents. In other words, some
mapping agents will always send mapping messages.
For compatibility, you can suppress mapping messages with the checkboxes. When
Mapping
Agent
is unchecked, the mapping agent stops sending mapping messages if it receives
messages from a mapping agent with a higher IP address.
Checking
No Mapping Agent
suppresses mapping messages. This means that the mapping
agent always sends mapping messages even in the presence of higher-addressed mapping
agents.
