DENSE MODE

Cisco recommends that you use ProtocolIndependent Multicast (PIM)

- Configure the global command ip

multicast-routing  and the interfacecommandip pim sparse-dense-mode oneach interface that needs to processmulticast trafficor you can configure theinterface commands ip pim dense-mode andip pim sparse-mode simultaneously with theip pim sparse-dense-modecommand.

SPARSE MODE WITH

ONE RP

- Static RP configuration requires that allrouters in the PIM domain have the sameip pim rp-address  commandsconfigured.

NOTE:

We can configure multiple RPs, but therecan only be one RP per specific group.

Router A is the RP which is typically theclosest router to the source

- This type of static RP configuration requires

that all routers in the PIM domain have the

same ip pim rp-addressaddress acl

commands configured.

NOTE: if we want different RPs to handle

different groups, you need to configure all

routers to include which groups the RPs will

serve

Only RP 1 or RP 2, can be the RP for all groups

- Auto-RP requires that you configure theRPs to announce their availability as RPsand mapping agents. The interface-typeoption in theip pim [vrf vrf-name]

send-rp-announce {interface-typeinterface-number or ip-address}

scope ttl-value command should containthe VLAN interface and the VLANnumber

NOTE: If you choose a physical interface,you rely on that interface to always be up

With a loopback interface, it is always upand never goes down, which ensures theRP continues to advertise itself throughany available interfaces as an RP
