The vrf parameter specified with the router pim command allows you to configure the max-mcache
command 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 available
system resources.
Defining the maximum number of multicast
VRF CAM entries
To use a run time command to set the maximum values for multicast VRF CAM entries for all VRFs
or for a specified VRF.
Defining the maximum number of multicast VRF CAM entries for all VRFs
You can use the following run-time command to define the maximum number of multicast VRF CAM
entries by entering a command such as the following.
Brocade(config)# ip multicast-max-all-vrf-cam 3072
Syntax: [no] ip multicast-max-all-vrf-cam num
The num variable specifies the maximum number of multicast VRF CAM entries for all VRFs. This
setting does not effect the default VRF. The maximum possible value is 32780 and the default
value is 2048.
Defining the maximum number of multicast VRF CAM entries for a specified VRF
You can use the following run-time command to define the maximum number of multicast VRF CAM
entries for a specified VRF by entering commands such as the following.
Brocade(config)# vrf vpn1
Brocade(config-vrf-vpn1)# ip multicast-max-cam 3072
Syntax: [no] vrf vrf-name
Syntax: [no] ip multicast-max-cam num
The vrf parameter specifies the virtual routing instance (VRF) specified by the variable vrf-name.
The num variable specifies the maximum number of multicast VRF CAM entries for the specified
VRF. This setting can be any number up to the limit set using the ip multicast-max-all-vrf-cam
command.
Defining the maximum number of IGMP group
addresses
You can use the following run-time command to set the maximum number of IGMP addresses for
the default VRF. To define this maximum for the default VRF, enter the following command.
Brocade(config)# ip igmp max-group-address 1000
Syntax: [no] ip igmp max-group-address num
