Brocade Communications Systems IPMC5000PEF manual Clearing the IPv6 PIM traffic

Clearing the IPv6 PIM traffic

The clear IPv6 pim rp-mapcommand allows you to update the entries in the static multicast forwarding table immediately after making RP configuration changes. This command is meant to be used with rp-addresscommand.

To update the entries in an IPv6 PIM Sparse static multicast forwarding table with a new RP configuration, enter the clear ipv6 pim rp-mapcommand at the privileged EXEC level of the CLI.

device(config)# clear ipv6 pim rp-map

Syntax: clear ipv6 pim [ vrf vrf-name] rp-map

Use the vrf parameter to clear the IPv6 PIM Sparse static multicast forwarding table for a VRF instance specified by the vrf-namevariable.

Clearing the IPv6 PIM traffic

To clear counters on IPv6 PIM traffic, enter the clear ipv6 pim traffic command.

device# clear ipv6 pim traffic

Syntax: clear ipv6 pim [ vrf vrf-name] traffic

Use the vrf par meter to clear counters on IPv6 PIM traffic for a VRF instance specified by the vrf- name variable.

Defining the maximum number of IPv6 PIM cache entries

You can use the max-mcachecommand to define the maximum number of repeated PIM traffic being sent from the same source address and being received by the same destination address. To define the maximum for the default VRF, enter the max-mcachecommand.

device(config)# ipv6 router pim device(config-ipv6-pim-router)# max-mcache 999

Syntax: [no] max-mcache num

The num variable specifies the maximum number of IPv6 multicast cache entries for PIM in the default VRF. If not defined by this command, the maximum value is determined by the system max command parameter, pim6-hw-mcache , or by available system resources.

To define the maximum number of IPv6 PIM Cache entries for a specified VRF, use the following command.

device(config)# ipv6 router pim vrf blue device(config-ipv6-pim-router-vrf-blue)# max-mcache 999

Syntax: [no] ipv6 router pim [ vrf vrf-name]

The vrf parameter specified with the ipv6 router pim command allows you to configure the max- mcache command for a virtual routing instance (VRF) specified by the variable vrf-name .

The vrf parameter specified with the router pim command allows you to configure the max-mcachecommand for a virtual routing instance (VRF) specified by the variable vrf-name .

The num variable specifies the maximum number of multicast cache entries for PIM in the specified VRF. If not defined by this command, the maximum value is determined by the system max command parameter, pim6-hw-mcache , or by available system resources.

There is a system-maxcommand parameter change with the following new runtime command:

Syntax: system-max pim6-hw-mcache
