Disabling and Reenabling Multicast Support
By default, DVMRP does the following:
• Propagates multicast routing information on the interface
• Incorporates in routing updates information about the source network
associated with this interface
• Forwards multicast datagrams on this interface in native mode -- that is, as
multicast datagrams
Using the BCC or Site Manager, you can disable multicast support on the
interface.
Using the BCC
To disable or reenable multicast support, navigate to a DVMRP interface prompt
(for example,
box; ethernet/2/2; ip/2.3.4.5/255.255.255.0; dvmrp
) and enter:
routing
<state>
state
is one of the following:
enabled
(default)
disabled
For example, the following command disables DVMRP multicast routing on IP
interface 2.3.4.5:
dvmrp/2.3.4.5#
routing disabled
dvmrp/2.3.4.5#
