Example: Sparse Mode with Auto-RP

Example: Sparse Mode with Auto-RP
The following example configures sparse mode with Auto-RP:
ip multicast-routing
ip pim autorp listener
ip pim send-rp-announce Loopback0 scope 16 group-list 1
ip pim send-rp-discovery Loopback1 scope 16
no ip pim dm-fallback
access-list 1 permit 239.254.2.0 0.0.0.255
access-list 1 permit 239.254.3.0 0.0.0.255
.
.
.
access-list 10 permit 224.0.1.39
access-list 10 permit 224.0.1.40
access-list 10 permit 239.254.2.0 0.0.0.255
access-list 10 permit 239.254.3.0 0.0.0.255

Example: Defining the IP Multicast Boundary to Deny Auto-RP Information

This example shows a portion of an IP multicast boundary configuration that denies Auto-RP information:
Device(config)# access-list 1 deny 224.0.1.39
Device(config)# access-list 1 deny 224.0.1.40
Device(config)# access-list 1 permit all
Device(config)# interface gigabitethernet1/0/1
Device(config-if)# ip multicast boundary 1

Example: Filtering Incoming RP Announcement Messages

This example shows a sample configuration on an Auto-RP mapping agent that is used to prevent candidate
RP announcements from being accepted from unauthorized candidate RPs:
Device(config)# ip pim rp-announce-filter rp-list 10 group-list 20
Device(config)# access-list 10 permit host 172.16.5.1
Device(config)# access-list 10 permit host 172.16.2.1
Device(config)# access-list 20 deny 239.0.0.0 0.0.255.255
Device(config)# access-list 20 permit 224.0.0.0 15.255.255.255
The mapping agent accepts candidate RP announcements from only two devices, 172.16.5.1 and 172.16.2.1.
The mapping agent accepts candidate RP announcements from these two devices only for multicast groups
that fall in the group range of 224.0.0.0 to 239.255.255.255. The mapping agent does not accept candidate
RP announcements from any other devices in the network. Furthermore, the mapping agent does not accept
candidate RP announcements from 172.16.5.1 or 172.16.2.1 if the announcements are for any groups in the
239.0.0.0 through 239.255.255.255 range. This range is the administratively scoped address range.
