Chapter 1 Implementing IPv6 Multicast
Implementing IPv6 Multicast
Implementing MLD Group Limits
Per-interface and global MLD limits operate independently of each other. Both per-interface and global
MLD limits can be configured on the same switch. The number of MLD limits, globally or per interface,
is not configured by default; the limits must be configured by the user. A membership report that exceeds
either the per-interface or the global state limit is ignored.
Implementing MLD Group Limits Globally
Beginning in privileged EXEC mode, follow these steps:
Implementing MLD Group Limits per Interface
Beginning in privileged EXEC mode, follow these steps:
Step 12
debug ipv6 mld [group-name | group-address |
interface-type]
Example:
Switch# debug ipv6 mld
Enables debugging on MLD protocol activity.
Step 13
debug ipv6 mld explicit [group-name |
group-address]
Example:
Switch# debug ipv6 mld explicit
Displays information related to the explicit tracking of hosts.
Step 14
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ipv6 mld [vrf vrf-name] state-limit number
Example:
Switch(config)# ipv6 mld state-limit 300
Limits the number of MLD states globally.
Step 3
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface type number
Example:
Switch(config)# interface FastEthernet 1/0
Specifies an interface type and number, and places the switch in
interface configuration mode.
Step 3
ipv6 mld limit number [except access-list
Example:
Switch(config-if)# ipv6 mld limit 100
Limits the number of MLD states on a per-interface basis.
Step 4
copy running-config startup-config (Optional) Save your entries in the configuration file.
