you see the following screen.
Chapter 27 DVMRP
DESCRIPTION
Select Active to enable DVMRP on the switch. You should do this if you want the switch to
act as a multicast router.
Threshold is the maximum time to live (TTL) value. TTL is used to limit the scope of
multicasting. You should reduce this value if you do not wish to flood Layer 3 devices many
hops away with multicast traffic. This applies only to multicast traffic this switch sends out.
Index is the DVMRP configuration for the IP routing domain defined under Network. The
maximum number of DVMRP configurations allowed is the maximum number of IP routing
domains allowed on the switch. See
routing domains.
This is the IP routing domain IP address and subnet mask you set up in IP Setup.
DVMRP cannot be enabled on the same VLAN group across different IP routing domains,
that is, you cannot have duplicate VIDs for different DVMRP configurations (see
on page
177).
Select Active to enable DVMRP on this IP routing domain.
Click Apply to save these changes to the switch.
Click Cancel to begin configuring this part of the screen afresh.
