Defining the Maximum Number of PIM Cache Entries

You can define the maximum number of multicast cache entries.

To define the maximum number of PIM cache entries for the default VRF, use the following steps. You can also define this number for a specific VRF when you add the VRF name to the router pim command in step 2.

Enter global configuration mode.
```
device# configure terminal
```

Enable PIM globally.
```
device(config)# router pim
```

Define the maximum number of PIM cache entries.
```
device(config-router-pim)# max-mcache 999
```

The following example defines the maximum number of PIM cache entries as 999.

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