graft-interval” command restores the default setting.
Parameter: <time_val> is the interval for sending DVMRP graft packets, ranging from 5
to 3600s.
Parameter: The default interval for sending DVMRP graft messages is 5s.
Command mode: Global Mode
Usage Guide: If a new receiver joins that interface when an interface is in the pruned
state, the interface will send a graft message to the upstream; if no graft ACK
message from the upstream is received, it will keep sending graft message to
the upstream at regular interval until an appropriate graft ACK is received.
Example: Set the interval for sending DVMRP graft messages to 10s.
Switch (Config)#ip dvmrp graft-interval 10
Command: ip dvmrp metric <metric_val>
no ip dvmrp metric
Function: Set interval for sending DVMRP report packets in the interface; the “no ip
dvmrp metric” command restores the default setting.
Parameter: < metric_val> is the route metric value, ranging from 1 to 32.
Default: The default tag value is 1.
Command mode: Interface Mode
Usage Guide: The routing information in a DVMRP report packet includes a list of source
network addresses and metrics. When DVMRP report packet metric is
configured on the interface, all route entries received on that interface will be
added the interface metric value configured to form a new metric value. The
metric value is used for poison reverse calculation to determine
upstream/downstream conditions. If a route metric in the local switch is
greater than 32 or equal to 32, then this route is unreachable. If after
calculation, the switch confirms itself in the downstream of a route, then a
report message containing that route will be sent to the upstream, with the
metric added by 32 to indicate the downstream position.
Example: Configure the DVMRP report packet metric to 2 on the interface.
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip dvmrp metric 2
Command: ip dvmrp nbr-timeout <time_val>
no ip dvmrp nbr-timeout
Function: Set timeout interval for DVMRP neighbors in the interface; the “no ip dvmrp
nbr-timeout” command restores the default setting.
Parameter: < time_val> is the time to timeout a neighbor, the valid range is 20 to 8000s.
Default: The default neighbor timeout setting is 35 seconds.
