enable loopback-mode vlan <vlan_name>

Assign the anycast RP address to the loopback VLAN with a 32 bit subnet mask using the 
following command:

configure {vlan} <vlan_name> ipaddress [<ipaddress> {<ipNetmask>} | 

ipv6-link-local | {eui64} <ipv6_address_mask>]

Enable IP forwarding and IP multicast forwarding on the loopback VLAN using the following 
commands:

enable ipforwarding {ipv4 | broadcast | ignore-broadcast | 

fast-direct-broadcast} {vlan <vlan_name>}

enable ipmcforwarding {vlan <name>}

Add the loopback VLAN into the unicast routing domain using the appropriate command for 
your unicast routing protocol:

configure ospf add vlan <vlan-name> area <area-identifier> link-type [auto | 

broadcast | point-to-point] {passive}

configure rip add vlan [<vlan-name> | all]

Add the loopback VLAN into the PIM-SM domain and configure it as an RP using the 
following commands:

configure pim add vlan [<vlan-name> | all] {dense | sparse} {passive}

configure pim crp static <ip_address> [none | <policy>] {<priority> [0-254]}

Enable MSDP and establish a peering relationship with similar anycast RP neighbors using 
the following commands:

create msdp peer <remoteaddr> {remote-as <remote-AS>} {vr <vrname>}

configure msdp peer [<remoteaddr> | all] password [none | {encrypted} 

<tcpPassword>] {vr <vrname>}

configure msdp peer <remoteaddr> description {<peer-description>} {vr 

<vrname>}

enable msdp [{peer} <remoteaddr> | peer all] {vr <vrname>}

enable msdp {vr <vrname>}

Configure a unique originator ID for each anycast RP peer using the following command:

configure msdp originator-id <ip-address> {vr <vrname>}

SA Cache

As an MSDP router learns of new sources either through a PIM-SM Source-Register (SR) 
message or SA message from its RPF peer, it creates an entry in SA cache (or refreshes the 
entry if it is already there) and forwards this information to its peers. These entries are 
refreshed by periodic SA messages received from the MSDP peers. If these entries are not 
refreshed within six minutes, they will time out. When a PIM-SM RP detects that the source is
