Hello Parajuli
Although Rene doesn’t go into details in the lesson, a router is configured as a mapping agent using the following command:
ip pim send-rp-discovery
You can find out more about this command at this Cisco Command Reference Documentation (search for ip pim send-rp-discovery
.
It is possible to configure two or more mapping agents within a network. Each will function independently. Engineers often misunderstand how multiple mapping agents interact and often believe that there is more complexity to such a configuration than there really is. Receiving mapping data from two or more mapping agents is not a problem because both transmit identical mapping information, so there are never any conflicts.
Conversely, the command ip pim send-rp-announce
configures a router as an RP.
I hope this has been helpful!
