Cisco Hoot and Holler over IP

Configuration Examples

	Command	Purpose
Step 8
	Router(config)# controller {t1 e1} number	Enters controller configuration mode and selects
		the T1 or E1 controller to configure.
Step 9
	Router(config-controller)# ds0-groupds0-group-no	Maps a group of time slots to a DS0 group.
	timeslots timeslot-list type type
Step 10
	Router(config-controller)# exit	Exits controller configuration mode.
Step 11
	Router(config)# voice-port	Enters voice-port configuration mode and
	{slot-number/subunit-number/port}	configures a DS0 group that was created in Step 9
	{slot/port:ds0-group-no}	in this configuration task table.
Step 12
	Router(config-voice-port)# connection {plar tie-line	Ties the connection trunk to a multicast address.
	plar-opx}digits {trunk digits [answer-mode]}	This command is repeated for each DS0 group. All
		groups use the same multicast address if
		connecting to the same multicast session. (Use the
		trunk keyword and the digit argument for hoot and
		holler applications.)
Step 13
	Router(config-voice-port)# voice-class permanent tag	Specifies the receive-only port.

Configuration Examples

This section provides a series of configuration examples to help you become familiar with voice multicasting. These examples also show how to ensure that each configuration is working properly before proceeding to the next step.

•Voice Multicasting over an Ethernet LAN, page 844

•Voice Multicasting over a WAN, page 847

•Cisco Hoot and Holler over IP with Ethernet Topology (Two Hoot Groups)

•Cisco Hoot and Holler over IP with Frame-Relay Topology (One Hoot Group)

Note In all the following configuration examples, the routers are configured with the interface command and the name tag vif1. This is a virtual interface that is similar to a loopback interface—it is a logical IP interface that is always up when the router is active. In addition, it must be configured so that the Cisco hoot and holler over IP packets that are locally mixed on the DSPs can be fast-switched along with the other data packets. This interface needs to reside on its own unique subnet, and that subnet should be included in the routing protocol updates (RIP, OSPF, and so on).
