A-6 APPENDIX A: IP MULTICAST ROUTING

	Example:
	Select IP stack by slot (2,3,7,9-12all) [12]:
	Enter an IP interface index [1]: 2
	Enter Interface DVMRP metric [1]: 1
	Enter Interface TTL threshold [1]:
	Enter interface rate limit in KBits/sec [0]:
Administering	A multicast tunnel allows multicast packets to cross several unicast routers
Multicast Tunnels	to a destination router that supports multicast. A tunnel has two end points.
	The local end point is associated with an interface on the CoreBuilder router.
	When you define the tunnel, you specify the associated index on the local
	CoreBuilder router and then the characteristics of the tunnel. Tunnel
	characteristics are the same as those of an interface. You also specify the IP
	address of the remote multicast router.
	Not all multicast configurations require a tunnel. The only configurations
	that require a tunnel are those that require a connection between two
	multicast internetworks through one or more unicast routers.
Displaying	To display the IP multicast tunnels on the router:
