IPv6 PIM Sparse 4<br />

Clearing the IPv6 PIM message counters<br />

You can clear the IPv6 PIM message counters using the clear ipv6 pim counters command.<br />

<strong>Brocade</strong># clear ipv6 pim counters<br />

Syntax: clear ipv6 pim [vrf vrf-name] counters<br />

Use the vrf parameter to clear the IPv6 PIM message counters for a VRF instance specified by the<br />

vrf-name variable.<br />

Updating PIM Sparse forwarding entries with<br />

a new RP configuration<br />

If you make changes to your static RP configuration, the entries in the IPv6 PIM Sparse multicast<br />

forwarding table continue to use the old RP configuration until they are aged out.<br />

The clear IPv6 pim rp-map command allows you to update the entries in the static multicast<br />

forwarding table immediately after making RP configuration changes. This command is meant to<br />

be used with rp-address command.<br />

To update the entries in an IPv6 PIM Sparse static multicast forwarding table with a new RP<br />

configuration, enter the clear ipv6 pim rp-map command at the privileged EXEC level of the CLI.<br />

<strong>Brocade</strong>(config)# clear ipv6 pim rp-map<br />

Syntax: clear ipv6 pim [vrf vrf-name] rp-map<br />

Use the vrf parameter to clear the IPv6 PIM Sparse static multicast forwarding table for a VRF<br />

instance specified by the vrf-name variable.<br />

Clearing the IPv6 PIM traffic<br />

To clear counters on IPv6 PIM traffic, enter the clear ipv6 pim traffic command.<br />

<strong>Brocade</strong># clear ipv6 pim traffic<br />

Syntax: clear ipv6 pim [vrf vrf-name] traffic<br />

Use the vrf par meter to clear counters on IPv6 PIM traffic for a VRF instance specified by the<br />

vrf-name variable.<br />

Defining the maximum number of IPv6 PIM cache entries<br />

You can use the max-mcache command to define the maximum number of repeated PIM traffic<br />

being sent from the same source address and being received by the same destination address. To<br />

define the maximum for the default VRF, enter the max-mcache command.<br />

<strong>Brocade</strong>(config)# ipv6 router pim<br />

<strong>Brocade</strong>(config-ipv6-pim-router)# max-mcache 999<br />

Syntax: [no] max-mcache num<br />
