Defining the maximum number of IPv6 PIM
cache entries
You can use the max-mcache command 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-mcache command.
Brocade(config)# ipv6 router pim
Brocade(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. The maximum value and the default value that can be entered is 4K. If not defined by
this command, the maximum value is determined by available system resources.
To define the maximum number of IPv6 PIM Cache entries for a specified VRF, use the following
command.
Brocade(config)# ipv6 router pim vrf blue
Brocade(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.
Defining the maximum number of IPv6 multicast
VRF CAM entries for all VRFs
You can use the following run-time command to define the maximum number of IPv6 multicast VRF
CAM entries for all non-default VRF instances by entering a command such as the following.
Brocade(config)# ipv6 multicast-max-all-vrf-cam 3072
Syntax: [no] ipv6 multicast-max-all-vrf-cam cam-size
The ipv6 multicast-max-all-vrf-cam command is configured at the global level. The cam-size
variable specifies the maximum number of multicast VRF CAM entries for all non-default VRF
instances. This setting does not affect the default VRF. The maximum possible value is 8000 and
the default value is 2048. The maximum cam-size can be configured from the vrf level as well but
is applied globally.
PIM Anycast RP
PIM Anycast RP is a method of providing load balancing and fast convergence to PIM RPs in an IPv6
multicast domain. The RP address of the Anycast RP is a shared address used among multiple PIM
routers, known as PIM RP. The PIM RP routers create an Anycast RP set. Each router in the Anycast
RP set is configured using two IP addresses: a shared RP address in their loopback address and a
separate, unique IP address. The loopback address must be reachable by all PIM routers in the
multicast domain. The separate, unique IP address is configured to establish static peering with
other PIM routers and communication with the peers.
