Configuring IPv4 Multicast Layer 3 Switching
This example shows how to enable IPv4 bidirectional PIM on the switch:
Router(config)# ip pim bidir-enable
Router(config)#
Configuring the Rendezvous Point for IPv4 Bidirectional PIM Groups
To statically configure the rendezvous point for an IPv4 bidirectional PIM group, perform this task:
Command
Step 1
Router(config)# ip pim rp-adress ip_address
access_list [override]
Step 2
Router(config)# access-list access-list permit |
deny ip_address
Step 3
Router(config)# ip pim send-rp-announce type
number scope ttl_value [group-list access-list]
[interval seconds] [bidir]
Step 4
Router(config)# ip access-list standard
access-list-name permit | deny ip_address
Step 5
Router(config)# mls ip multicast
This example shows how to configure a static rendezvous point for an IPv4 bidirectional PIM group:
Router(config)# ip pim rp-address 10.0.0.1 10 bidir override
Router(config)# access-list 10 permit 224.1.0.0 0.0.255.255
Router(config)# ip pim send-rp-announce Loopback0 scope 16 group-list c21-rp-list-0 bidir
Router(config)# ip access-list standard c21-rp-list-0 permit 230.31.31.1 0.0.255.255
Setting the IPv4 Bidirectional PIM Scan Interval
You can specify the interval between the IPv4 bidirectional PIM RP Reverse Path Forwarding (RPF)
scans.
To set the IPv4 bidirectional PIM RP RPF scan interval, perform this task:
Command
Router(config)# mls ip multicast bidir
gm-scan-interval interval
Router(config)# no mls ip multicast bidir
gm-scan-interval
This example shows how to set the IPv4 bidirectional PIM RP RPF scan interval:
Router(config)# mls ip multicast bidir gm-scan-interval 30
Router(config)#
OL-11439-03
Purpose
Specifies the IPv4 bidirectional PIM RP RPF scan interval;
valid values are from 1 to 1000 seconds. The default is 10
seconds.
Restores the default.
Catalyst Supervisor Engine 32 PISA Cisco IOS Software Configuration Guide, Release 12.2ZY
Purpose
Statically configures the IP address of the rendezvous
point for the group. When you specify the override
option, the static rendezvous point is used.
Configures an access list.
Configures the system to use Auto-RP to configure
groups for which the router will act as a rendezvous point
(RP).
Configures a standard IP access list.
Enables MLS IP multicast.
