Configures a DVMRP tunnel to function as a default route for IP multicast
traffic on a DVMRP interface. This tunnel advertises itself as a default
route to neighboring DVMRP routers.

ip m d t d
Important Considerations
A default tunnel metric of 0 means that the default route function is
not activated on the interface (interface does not advertise 0.0.0.0 to
DVMRP routers). Values other than 0 means that the default route
function is activated and these values represent the "cost" of the
default route.
Definitions of default tunnel modes:
all — The interface advertises the default route plus all other
known routes to neighboring DVMRP routers.
only — The interface advertises only the default route to
neighboring DVMRP routers.
If the module learns a default tunnel, it propagates it no matter which
mode is set on a given interface.
The module allows you to configure an interface as a DVMRP default
route, even when DVMRP is disabled on the interface. If DVMRP is
disabled, the interface does not advertise itself as a default route.
If a tunnel is not configured as a default route, the default metric is set
to by default and the route advertising mode is set to
0
You can configure a default route at one end of a tunnel only. You do
not have to also configure the associated local interface as a default
route.
