Configuring IP Multicasting
7-19
Parameter: Pruning Enable
Default: Enable
Options: EnableDisable
Function: Enables or disables pruning functionality on the router.
Instructions: DVMRP performs route pruning by default. If you want to disable this
function on the router, select Disable.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.12.1.15
Parameter: Fragmented MTU Threshold
Default: 1514
Range: 910 to 1514 bytes
Function: Specifies a maximum transmission unit (MTU) size. The maximum (and
default) size is the CSMACD_MTU size. The minimum is the
X25_DDN_MTU size.
Instructions: DVMRP compares datagrams received by the router with the threshold
value you specify. If the size of the datagram exceeds the threshold size,
IP fragments the datagram. DVMRP makes this decision based on the
comparison between the outgoing interface’s MTU and either this
threshold value, if you configure it, or the incoming interface’s MTU.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.12.1.16
Parameter: Max Routes
Default: 0
Options: 0 or an integer
Function: Specifies the number of routes that DVMRP can learn per slot. This
parameter limits the number of routes that can be stored in the routing
table.
Instructions: If you want DVMRP to store all learned routes in the routing table, use
the default, 0. If you specify a maximum number of routes, you must
include a route for every local network that has a circuit configured for
multicasting.
