Configuring IP Multicasting Services
4-18 114064 Rev. A
Disabling Advertisement of Local Networks
By default, DVMRP advertises its own local networks over this circuit. Using Site
Manager, you can configure DVMRP so that it does not advertise local networks
over the circuit.
Configuring a Tunnel
The following sections show you how to use Site Manager to configure a DVMRP
tunnel.
Enabling and Disabling the Tunnel
When you configure a tunnel on a circuit, the tunnel is enabled by default. You
can use Site Manager to disable and re-enable the tunnel.
Selecting the Encapsulation Mode
By default, DVMRP encapsulates a tunneled multicast datagram in an IP unicast
datagram. Using Site Manager, you can configure DVMRP to loosely encapsulate
multicast datagrams using the LSSR option.
See RFC 1075 for information about the LSSR option, which is provided for
backward compatibility.
