  no ip dvmrp distance admin-distance  
  admin-distance  
  The default administrative distance (0 255).  
 
  IOS Version  
  11.2  
 
  This command configures the default administrative distance for received DVMRP routes. It should be used so that routes advertised from the unicast routing table that are reflected back through DVMRP cause the original unicast routes to continue to be advertised. The ip dvmrp accept-filter command can override this value when specified on an interface.  
  ip dvmrp route-hog-notification count  
  no ip dvmrp route-hog-notification count  
  count  
  Number of routes allowed before a syslog message is sent. The default is 10,000 routes.  
 
  IOS Version  
  10.2

  ip dvmrp route-limit count  
  no ip dvmrp route-limit count  
  count  
  The number of DVMRP routes that can be advertised. The default value is 7000.  
 
  IOS Version  
  11.0  
 
  Interface Configuration Commands  
  ip dvmrp accept-filter access-list-number [distance] neighbor-list access-list-number  
  no ip dvmrp accept-filter access-list-number [distance] neighbor-list access-list-number

  access-list-number  
  IOS Version  
  10.2  
 
  ip dvmrp auto-summary  
  IOS Version  
  11.2

  IOS Version  
  10.2  
 
  This interface command is used to advertise the default network 0.0.0.0. to the DVMRP neighbor on the interface. The originate option allows more specific routes to be advertised. The only keyword prevents other routes from being advertised. Do not use this command to create a default route to the MBONE.

  list access-list  
  Optional. A standard IP access list can be used to control which routes are reported.  
 
  protocol  
  Optional. The unicast routing protocol name (rip, igrp, eigrp, ospf, bgp, isis, static, or dvmrp).

  IOS Version  
  11.0  
 
  Use this interface command to adjust the metric of DVMRP routes being received on an interface (in) or reported to a neighbor (out). The default value when applied to incoming routes is 1 and the default value applied to outgoing routes is 0. Be careful, this command adds the same metric to all incoming or outgoing routes.  
  ip dvmrp output-report-delay delay-time [burst]  
  no ip dvmrp output-report-delay delay-time [burst]  
  delay-time  
  The number of milliseconds between DVMRP route reports.

  tunnel mode dvmrp  
  no tunnel mode dvmrp  
  IOS Version  
  10.2  
 
  This configures a Cisco tunnel to encapsulate IP using protocol number 4. This mode can be used when a Cisco connects to a mrouted machine to run DVMRP over a tunnel. This is a popular way to connect to the MBONE. It is required to configure PIM and an IP address on a DVMRP tunnel. This mode is not used to construct a tunnel between a pair of Cisco routers.  
  ip dvmrp unicast-routing.  
  no ip dvmrp unicast-routing.

  distributed  
  This enables distributed fast-switching on the interface.  
 
  IOS Version  
  11.0  
 
  Multicast packets can either be process-switched or fast-switched on an interface and this command configures IP multicast fast-switching. The default setting is when all interfaces are multicast fast-switched.  
  ip sdr listen  
  no ip sdr listen  
  IOS Version:  11.1  
  This command enables the router to accept SDAP packets on the interface and the router joins the multicast group 224.2.127.254. SDR entries are cached on the router and the time that an SDR remains in the cache is configured using the global configuration command.

  IOS Version  
  10.2  
 
  show ip pim rp [group-name | group-address | mapping]  
  group-name  
  Optional. Shows RPs for the named group.  
 
  group-address  
  Optional. Shows RPs for the group with the entered group address.  
 
  mapping  
  Optional. Displays all group to RP mappings.  
 
  IOS Version  
  10.2  
 
  show ip mroute [[group-name | group-address] [source-address]] [summary]  
  This displays the IP multicast routing table. When summary is specified, a one-line abbreviated display is provided. When count is specified, group count, source count, and packet count statistics are provided ([10.2]).  
  show ip mroute [[group-name | group-address] [source-address]] count  
  This displays the packet count per the (S,G) multicast routing table entry. It also includes the average packet size and data rate in kilobits per second ([10.2]).  
  show ip mroute [<group-name | group-address] active [kbps]  
  This command shows you the rate that active sources send to multicast groups. You can display for all groups or specify a single group. [kbps] only displays sources that are sending greater than or equal to itself. The default setting shows all sources sending at a rate greater than or equal to one kilobit per second. If SD is running on the router, the SD session name is displayed ([11.0]).  
  RSVP Commands  
  Interface Commands  
  ip rsvp bandwidth interface-kbps single-flow-kbps  
  no ip rsvp bandwidth interface-kbps single-flow-kbps  
  interface-kbps  
  Optional parameter. Its value can be from 1 10,000,000.  
 
  single-flow-kbps  
  Optional parameter. Its value can be 1 10,000,000.  
 
  The parameters shown in brackets are optional parameters. The first optional parameter is the total amount of bandwidth that will be reserved on the interface for RSVP flows. The second optional parameter is the amount of bandwidth that can be allocated to a single flow. By default, 75 percent of the bandwidth on an interface can be reserved.  
  ip rsvp neighbors access-list-number  
  no ip rsvp neighbors access-list-number  
  access-list-number  
  Integer from 1 to 199. 1 to 99 for a standard access list. 100 to 199 for an extended access list.  
 
  By default, any neighbor can request a reservation on a router interface. If only selected neighbors are to be permitted to request a reservation using RSVP, we would use this interface command for PATH messages:  
  ip rsvp sender session-ip-address sender-ip-address  
  [tcp|udp|ip-protocol] session-dport sender-sport  
  previous-hop-ip-address previous-hop-interface bandwidth burst-size  
  We would use this command for RESV messages:  
  ip rsvp reservation session-ip-address sender-ip-address  
  [tcp|udp|ip-protocol] session-dport sender-sport  
  next-hop-ip-address next-hop-interface  
  {ff|se|wf} {rate|load} bandwidth burst-size  
  The explanations of the parameters for the two messages are listed below.  
  session-ip-address  
  For a unicast session, this is the address of the receiver. For a multicast session, this is the session IP multicast address.  
 
     
  The IP address of the sender.  
 
  tcp|udp|ip-protocol  
  session dport  
  The destination and source port numbers. If one is session sport zero, then it will be session sport; otherwise, both must be zero.  
 
  previous-hop-ip-address  
  The address of the sender if the sender is connected to the interface or address of the router interface on the path back to the sender.  
 
  previous-hop-interface  
  The interface type of the previous hop, which can be ethernet, loopback, null, or serial.  
 
  next-hop-ip-address  
  The hostname or address of the receiver, or the address of the router interface on the path back to the receiver.  
 
  next-hop-interface  
  The interface type of the next hop, which can be ethernet, loopback, null, or serial.  
 
  ff | se | wf  
  The reservation style, which can be fixed filter, shared explicit, or wild card.  
 
  rate | load  
  Quality of Service s guaranteed bit rate service or controlled load service.  
 
  bandwidth  
  Optional. The average bit rate (in kbps) to reserve, which can be up to 75 percent of the interface capacity. Its range is from 1 to 10,000,000.  
 
  burst-size  
  Optional. The maximum burst size (in kilobytes of data in the queue). Its range is from 1 to 65,535.  
 
  To remove the effect, use the no form of the command.  
  ip rsvp udp-multicast multicast-address  
  no ip rsvp udp-multicast multicast-address  
  Configures the router to generate UDP-encapsulated RSVP multicasts.
