Defining the maximum number of PIM cache entries

Defining the maximum number of PIM cache entries

You can use the following run-time 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 this maximum for the default VRF, enter the following commands.

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

Syntax: [no] max-cache num

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

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

device(config)# router pim vrf vpn1 device(config-pim-router-vrf-vpn1)# max-mcache 999

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

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

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-maxcommand option pim-hw-mcacheor by available system resources.

Defining the maximum number of IGMP group addresses

You can use the ip igmp max-group-addressrun-time command to set the maximum number of IGMP addresses for the default virtual routing and forwarding (VRF) instance or for a specified VRF. To define this maximum for the default VRF, enter the following command.

device(config)# ip igmp max-group-address 1000

Syntax: [no] ip igmp max-group-address num

The num variable specifies the maximum number of IGMP group addresses for all VRFs, including the default VRF. If not defined by this command, the maximum value is determined by available system resources.

To define this maximum for a specified VRF, enter the following commands.

device(config)# vrf vpn1 device(config-vrf-vpn1)# address-family ipv4 device(config-vrf-vpn1-ipv4)# ip igmp max-group-address 1000

Syntax: [no] vrf vrf-name

Syntax: [no] address-family ipv4

Syntax: [no] ip igmp max-group-address num

The vrf parameter specifies the VRF instance specified by the vrf-namevariable.

The num parameter specifies the number of IGMP group addresses that you want to make available for the specified VRF. If not defined by this command, the maximum value is determined by available system resources.
