Chapter 42 IPv6 Multicast
Configuring IPv6 Multicast
Configuring a Rendezvous Point
To configure a rendezvous point (RP) in a Protocol Independent Multicast sparse mode (PIM-SM)
network, see the Configuring a Rendezvous Point guide at:
http://www.cisco.com/en/US/docs/ios/solutions_docs/ip_multicast/White_papers/rps.html
This guide provides scenario descriptions and basic configuration examples for the following options:
• Static RP
• Bootstrap router
• Anycast RP
Step 4
ipv6 mld query-interval
seconds
Example:
Router(config-if)# ipv6 mld
query-interval 60
Configures the frequency of MLD Host-Query packets transmitted.
A designated router for a LAN is the only router that transmits
queries. The default value is 60 seconds.
Step 5
ipv6 mld query-max-response-time
seconds
Example:
Router(config-if)# ipv6 mld
query-max-response-time 20
Specifies the maximum query response time advertised in the MLD
queries. Default value is 10 seconds. Configuring a value less than
10 seconds enables the router to prune groups faster.
Step 6
ipv6 mld query-timeout
seconds
Example:
Router(config-if)# ipv6 mld
query-timeout 130
Specifies the timeout for the router to take over as the querier for the
interface, after the previous querier has stopped querying. The
default value is 2 * query-interval. If the router hears no queries for
the timeout period, it becomes the querier.
Step 7
ipv6 mld join-group [
group-address
]
[[include | exclude] {
source-address
|
source-list [
acl
]}
Example:
Router(config-if)# ipv6 mld join-group
FF04::12 exclude 2001:DB8::10::11
Configures MLD reporting for given group with MLDv1 or given
source and group with MLDv2. The packets that are addressed to
this group address are passed up to the client process in the router
as well forwarded out the interface.
Step 8
ipv6 mld static-group [
group-address
]
[[include | exclude] {
source-address
|
source-list [
acl
]}
Example:
Router(config-if)# ipv6 mld
static-group ff04::10 include 100::1
Configures forwarding of traffic for the multicast group onto this
interface and behave as if an MLD joiner was present on the
interface. The packets to the group get fastswitched or hardware
switched (whatever is available on the platform).
Note This command is not a sufficient condition for traffic to be
forwarded onto the interface. Other conditions such as
absence of a route, not being the DR or losing an assert can
cause the router to not forward traffic even if the command
is configured.
