Configuring DVMRP
Purpose
To
enable
and
configure
the
Distance
Vector
Multicast
Routing
Protocol
(DVMRP)
on
an
interface.
DVMRP
routes
multicast
traffic
using
a
technique
known
as
Reverse
Path
Forwarding.
When
a
router
receives
a
packet,
it
floods
the
packet
out
of
all
paths
except
the
one
that
leads
back
to
the
packet’s
source.
Doing
so
allows
a
data
stream
to
reach
all
VLANs
(possibly
multiple
times).
If
a
router
is
attached
to
a
set
of
VLANs
that
do
not
want
to
receive
from
a
particular
multicast
group,
the
router
can
send
a
“prune”
message
back
up
the
distribution
tree
to
stop
subsequent
packets
from
traveling
where
there
are
no
members.
DVMRP
will
periodically
reflood
in
order
to
reach
any
new
hosts
that
want
to
receive
from
a
particular
group.

Use
this
command

DVMRP
process:
