Configuring and Modifying DVMRP
Distance Vector Multicast Routing Protocol (DVMRP) uses IP packets with
protocol type 2 (IGMP) to exchange routing datagrams. DVMRP enables
multicast routers to exchange distance vector updates that contain multicast
flow lists and their corresponding cost metrics. DVMRP may use tunneling
Process Leave
Packets turns off processing of IGMP leave messages when set
to disable. The default value is Enable.
Query Request
Interval in (sec) Enter a time period between queries.
The valid range for this field is 1 to 65,535. The default
setting is 125 seconds.
Query Response
Interval in (sec) Enter a time (in seconds) to wait for a response from a
host after a query is sent. If no response is received
within this time, the host is removed from the group
table.
The valid range for this field is 1 to 25. The default
setting is 10 seconds.
Neighbor Querier
Timeout Interval in
(sec) Enter a time (in seconds) this interface should wait after
hearing a neighbor’s query before assuming the role of
querier, if not already the querier. If no query is
received from a neighbor with a lower IP address in the
allotted time, this interface becomes the querier (IGMP
Version 2.0 only).
The valid range for this field is 30-600. The default
setting is 255 seconds.
Robustness Variable Modify this field for any expected packet loss on a
subnet. If a subnet is expected to have more packet loss,
the Robustness Variable should be increased. The
Robustness Variable must not be set to 0 and should not
be set to 1.
The valid range for this field is 1 to 65,535. The default
setting is 2.
