Multicast and Routing Guide K/KA/KB.15.15

Example 18 Configuring PIM in the Global and PIM context
In Figure 11 (page 58), the "#1" routing switch is directly connected to the multicast sources for
the network. For this example, suppose that you are choosing the following:
• Reduce the state-refresh time from the default 60 seconds to 30 seconds. (The routing switch
transmits state-refresh packets only if it is directly connected to the multicast source.)
• Configure an SNMP trap to notify your network management station if the routing switch's
hardware multicast routing table becomes filled to the maximum of 2048 active flows.
To configure global-level PIM operation for the "8212zl #1" routing switch, you would use the
commands shown in Figure 7 (page 39).

After configuring the global-level PIM operation on a routing switch, go to the device's VLAN
context level for each VLAN you want to include in your multicast routing domain. See Table 5
(page 52).
