Monitoring RIP

Two sets of commands enable you to monitor RIP operation on your router: the debug and the show commands. Both sets of commands provide information about your router’s RIP state and configuration.

The task you are performing with each of these monitoring commands is basically the same for each command; that is, you are requesting information. The results of this request may vary. For instance, the debug commands provide information about problems with the network or the router, whereas the show commands provide information about the actual state and configuration of your router.

debug Commands

The debug commands provide information about the following RIP items:

General events, such as creating a RIP process or removing RIP from an interface
Routing events, such as when two RIP routers exchange routes

debug ip rip

Use to display information about selected RIP events. This command has many keywords that allow you to specify a variety of RIP events.
You can set the level of severity for the events you want displayed; specify the desired descriptive term or a corresponding number (0–7).
You can set the verbosity of the messages you want displayed: low, medium, high.
Example
host1#debug ip rip events
Use the no version to cancel the display of any information about the designated variable.
See debug ip rip

undebug ip rip

Use to cancel the display of information about a selected event.
The same RIP variables can be designated as in the debug ip rip command.
Example
host1#undebug ip rip events
There is no no version.
See undebug ip rip

show Commands

Use the show commands to monitor the following types of RIP information:

Configuration
IP-related information
Global counters
Counters for a specified network
Statistics

You can set a statistics baseline for RIP interfaces by using the baseline ip rip command.

You can specify a VRF instance for the show ip rip commands. You can use the output filtering feature of the show command to include or exclude lines of output based on a text string you specify. See JunosE System Basics Configuration Guide, for details.

baseline ip rip

Use to set a statistics baseline for RIP interfaces.
The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
Use the optional delta keyword with the show ip rip statistics command to specify that baselined statistics are to be shown.
Example
host1#baseline ip rip
There is no no version.
See baseline ip rip

show ip rip

Use to display RIP information.
Specify vrf vrfName to limit the display to a specific VRF.
Use the ifconfig keyword to display address and interface configuration information instead of the default operational data.
Field descriptions
- Router Information Protocol Fields
  - Router Administrative State—Displays the RIP state. Enable means the router is allowed to send and receive updates. Disable means that RIP might be configured but it is not allowed to run yet.
  - System version RIP1—RIP versions allowed for sending and receiving RIP updates. The router version is currently set to RIP1, which sends RIPv1 but will receive RIPv1 or RIPv2. If it is set to RIP2, it will send and receive RIPv2 only. The default is configured for RIP1.
  - Incoming filters—Access list applied to incoming route updates
  - Outgoing filters—Access list applied to outgoing route updates
  - Global route map—Route map that specifies all RIP interfaces on the router
  - Default metric—Value for redistributed routes. The default is 1. This global value is superseded by metrics applied to a RIP interface.
  - Distance—Value added to RIP routes added to the IP routing table. The default is 120.
  - Number of route changes—Number of times the router has been told to route changes by its peers
  - Number of route queries—Number of times the router has received route requests from other routers
  - Update interval—Current setting of the update timer (in seconds)
  - Invalid interval—Current setting of the invalid timer (in seconds)
  - Hold down time—Current setting of the hold-down timer (in seconds)
  - Flush interval—Current setting of the flush timer (in seconds)
  - Route Type—Whether RIP routes are available only for unicast forwarding, only for multicast reverse path forwarding checks, or for both
  - Max Ecmp Paths—Number of parallel routes that RIP can support

  - Triggered Updates—Ability (enabled or disabled) of RIP to send triggered updates
  - Purge Routes on Interface Down Event—Ability (enabled or disabled) of RIP to purge the routing table for interfaces that were brought down by some event
  - Send More Specific Routes—Ability (enabled or disabled) of RIP to send a less-specific route in preference to a more-specific route if the less-specific route has a metric
  - Debounce Time—Debounce time for interfaces brought down by some event
  - Default-Information originate—Ability (enabled or disabled) of RIP to advertise a default route (0.0.0.0/0) if the default route exists in the IP routing table

    is 1.
  - BFD minimum receive interval(msec)—Configured minimum interval requested between BFD control packets sent by the remote RIP peer; used with RIP peers to negotiate a detection interval for BFD session failure. The default is 300 milliseconds.
  - BFD minimum transmit interval(msec)—Configured minimum interval between BFD control packets sent by the local RIP peer; used with RIP peers to negotiate a detection interval for BFD session failure. The default is 300 milliseconds.
  - BFD multiplier—Multiplied by the negotiated BFD minimum receive interval to determine the interval between packets permitted before the BFD session is declared down. Also, the number of BFD control packets that the RIP local peer can miss before the BFD session is declared down. The default is 3.
  - Passive Interface—Whether or not the interface is passive, thereby restricting the interface to unicast RIP messages
  - Passive Interface—Whether or not the interface is passive, thereby restricting the interface to unicast RIP messages
  - Access-list applied to outgoing route—Name of the access list applied to outgoing routes
