Chapter 16  
DVMRP Commands  
  


-----------------------------------------------------------------------------
--- 

  

default-gateway  
Defines the default gateway for DVMRP IP multicast routing. If designated as 
the default gateway, the router must be on a directly connected network for 
this command to be operational.  

EXAMPLE:  

BigIron(config)# router dvmrp  

BigIron(config-dvmrp-router)# default-gateway 192.35.4.1  

Syntax: default-gateway <ip-addr> 

Possible values: valid IP address 

Default value: no system default 


-----------------------------------------------------------------------------
--- 

  

end  
Moves activity to the privileged EXEC level from any level of the CLI 
except the user EXEC level. 

EXAMPLE:  

To move to the privileged level, enter the following from any level of the 
CLI.  

BigIron(config-dvmrp-router)# end  

BigIron#  

Syntax: end 

Possible values: N/A 

Default value: N/A 


-----------------------------------------------------------------------------
--- 

  

exit  
Moves activity up one level from the current level. In this case, activity 
will be moved to the global level. 

EXAMPLE:  

BigIron(config-dvmrp-router)# exit  

BigIron(config)#  

Syntax: exit 

Possible values: N/A 

Default value: N/A 


-----------------------------------------------------------------------------
--- 

  

graft-retransmit-timer  
Defines the initial period of time that a DVMRP router sending a graft 
message, will wait for a graft acknowledgment from an upstream router, 
before re-transmitting that message. 

Subsequent re-transmissions will be sent at an interval of twice that of 
the preceding interval.  

DVMRP must be enabled on the router for this command to be operational.  

EXAMPLE:  

BigIron(config)# router dvmrp  

BigIron(config-dvmrp-router)# graft 120  

Syntax: graft-retransmit-timer <value> 

Possible values: 5 - 3600 seconds 

Default value: 10 seconds 


-----------------------------------------------------------------------------
--- 

  

nbr-timeout  
Sets neighbor timeout value, which is the period of time that a router will 
wait before it defines an attached DVMRP neighbor router as down. 

DVMRP must be enabled on the router for this command to be operational.  

EXAMPLE:  

BigIron(config)# router dvmrp  

BigIron(config-dvmrp-router)# nbr-timeout 100  

Syntax: nbr-timeout <value> 

Possible values: 40 - 8000 seconds 

Default value: 40 seconds 


-----------------------------------------------------------------------------
--- 

  

no  
Disables other commands. To disable a command, place the word no before the 
command.  


-----------------------------------------------------------------------------
--- 

  

probe-interval  
Defines how often neighbor probe messages are sent to the ALL-DVMRP-ROUTERS 
IP multicast group address. A router's probe message lists those neighbor 
DVMRP routers from which it has received probes. 

DVMRP must be enabled on the router for this command to be operational.  

EXAMPLE:  

BigIron(config)# router dvmrp  

BigIron(config-dvmrp-router)# probe 10  

Syntax: probe-interval <value> 

Possible values: 5 - 30 seconds 

Default value: 10 seconds 


-----------------------------------------------------------------------------
--- 

  

prune-age  
Defines how long a prune state will remain in effect for a source-routed 
multicast tree. After the prune age period expires, flooding will resume. 

DVMRP must be enabled on the router for this command to be operational. 

EXAMPLE:  

BigIron(config)# router dvmrp  

BigIron(config-dvmrp-router)# prune 25  

Syntax: prune-age <value> 

Possible values: 20 - 3600 seconds 

Default value: 180 seconds  


-----------------------------------------------------------------------------
--- 

  

quit  
Returns you from any level of the CLI to the User EXEC mode. 

EXAMPLE:  

BigIron(config-dvmrp-router)# quit  

BigIron>  

Syntax: quit 

Possible values: N/A 

Default value: N/A 


-----------------------------------------------------------------------------
--- 

  

report-interval  
Defines how often routers will propagate their complete routing tables to 
other neighbor DVMRP routers. 

DVMRP must be enabled on the router for this command to be operational.  

EXAMPLE:  

BigIron(config)# router dvmrp  

BigIron(config-dvmrp-router)# report 100  

Syntax: report-interval <value> 

Possible values: 10 - 2000 seconds 

Default value: 60 seconds 


-----------------------------------------------------------------------------
--- 

  

route-discard-timeout  
Defines the period of time before a route is deleted on a DVMRP router.  

DVMRP must be enabled on the router for this command to be operational.  

EXAMPLE:  

BigIron(config)# router dvmrp  

BigIron(config-dvmrp-router)# route-discard-timeout 50  

Syntax: route-discard-timeout <value> 

Possible values: 40 - 8000 seconds 

Default value: 340 seconds 


-----------------------------------------------------------------------------
--- 

  

route-expire-timeout  
Defines how long a route is considered valid without the next route update. 

DVMRP must be enabled on the router for this command to be operational.  

EXAMPLE:  

BigIron(config)# router dvmrp  

BigIron(config-dvmrp-router)# route-expire-time 50  

Syntax: route-expire-time <value> 

Possible values: 20 - 4000 seconds 

Default value: 200 seconds 


-----------------------------------------------------------------------------
--- 

  

show  
Displays a variety of configuration and statistical information about the 
device. See "Show Commands" . 


-----------------------------------------------------------------------------
--- 

  

trigger-interval  
Defines how often trigger updates, which reflect changes in the network 
topology, are sent. Changes in a network topology can include a router 
coming up or going down or changing its metric.  

DVMRP must be enabled on the router for this command to be operational.  

EXAMPLE:  

BigIron(config)# router dvmrp  

BigIron(config-dvmrp-router)# trigger-interval 25  

Syntax: trigger-interval <value> 

Possible values: 5 - 30 seconds 

Default value: 5 


-----------------------------------------------------------------------------
--- 

  

write memory  
Saves the running configuration into the startup-config file. 

EXAMPLE:  

BigIron(config-dvmrp-router)# wr mem  

Syntax: write memory 

Possible values: N/A 

Default value: N/A 


-----------------------------------------------------------------------------
--- 

  

write terminal  
Displays the running configuration of the Foundry device on the terminal 
screen. 


-----------------------------------------------------------------------------
--- 
NOTE: This command is equivalent to the show running-config command.  
-----------------------------------------------------------------------------
--- 

EXAMPLE:  

BigIron(config-dvmrp-router)# wr term  

Syntax: write terminal
