Command Usage
• The specified interface advertises itself as a default route to neighboring
DVMRP routers. It advertises the default route out through its other
interfaces. Neighboring routers on the other interfaces return Poison
Reverse messages for the default route back to the router. When the
router receives these messages, it records all the downstream routers
for the default route.
• When multicast traffic with an unknown source address (not found in the
route table) is received on the default upstream route interface, the
router forwards this traffic out through the other interfaces (with known
downstream routers). However, when multicast traffic with an unknown
source address is received on another interface, the router drops it
