NETGEAR 8800 User Manual enable loopback-mode vlan 2. Assign the anycast RP address to the loopback VLAN with a 32 bit subnet mask using the following command: configure {vlan} ipaddress [ {} | ipv6-link-local | {eui64} ] Note: The anycast RP address must be unique to the loopback VLAN and be the same on all anycast RP peers. It must not match the router IP address, the PIM BSR address, or any other IP addresses used by the router or any other network devices. 3. 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 } enable ipmcforwarding {vlan } 4. Add the loopback VLAN into the unicast routing domain using the appropriate command for your unicast routing protocol: configure ospf add vlan area link-type [auto | broadcast | point-to-point] {passive} configure rip add vlan [ | all] 5. Add the loopback VLAN into the PIM-SM domain and configure it as an RP using the following commands: configure pim add vlan [ | all] {dense | sparse} {passive} configure pim crp static [none | ] { [0-254]} 6. Enable MSDP and establish a peering relationship with similar anycast RP neighbors using the following commands: create msdp peer {remote-as } {vr } configure msdp peer [ | all] password [none | {encrypted} ] {vr } configure msdp peer description {} {vr } enable msdp [{peer} | peer all] {vr } enable msdp {vr } 7. Configure a unique originator ID for each anycast RP peer using the following command: configure msdp originator-id {vr } 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 768 | Chapter 29. MSDP
