Anycast RP with Auto RP

Anycast-RP with Auto-RP

Is the cisco documentation correct?

You have two routers config'd as CRPs and mapping agents. The documentation shows the following config:-

R1

interface Loopback0

ip address 20.0.0.3 255.255.255.255

ip pim sparse-dense-mode

interface Loopback1

ip address 20.0.0.1 255.255.255.255

ip pim sparse-dense-mode

ip pim rp-address 1.1.1.1 20

ip pim send-rp-announce Loopback1 scope 32 group-list 10

ip pim send-rp-discovery Loopback1 scope 32

ip msdp peer 20.0.0.2 connect-source Loopback0

ip msdp mesh-group anycast 20.0.0.2

ip msdp originator-id Loopback0

access-list 10 permit 224.0.0.0 15.255.255.255

access-list 20 deny 224.0.1.39

access-list 20 deny 224.0.1.40

access-list 20 permit 224.0.0.0 15.255.255.255

R2

interface Loopback0

ip address 20.0.0.2 255.255.255.255

ip pim sparse-dense-mode

interface Loopback1

ip address 20.0.0.1 255.255.255.255

ip pim sparse-dense-mode

ip pim rp-address 1.1.1.1 20

ip pim send-rp-announce Loopback0 scope 32 group-list 10

ip pim send-rp-discovery Loopback0 scope 32

ip msdp peer 20.0.0.3 connect-source Loopback0

ip msdp mesh-group anycast 20.0.0.3

ip msdp originator-id Loopback0

access-list 10 permit 224.0.0.0 15.255.255.255

access-list 20 deny 224.0.1.39

access-list 20 deny 224.0.1.40

access-list 20 permit 224.0.0.0 15.255.255.255

On the "send-rp-announce" command, should the interface not be the anycast loopback on both routers so that all group-rp-mappings go out with the anycast ip address.

Many thx

You are correct, this must be a typing mistake.

Come on Cisco, do some proof-reading before publishing.......................

Ken, you obviously understand the mechanics of Auto-RP and Anycast, so go with your instinct on this one ;o)
