13.10 Activating RSVP Signaling Options


In the JUNOS environment RSVP will be enabled on a per-interface basis.

  1. From the configuration mode, type the following commands to enable RSVP.

     [edit protocols rsvp]  lab@Chicago#set interface fe-1/0/3 

    This command will enable RSVP on the fe-1/0/3 interface.

  2. If RSVP is to be enabled on all interfaces on the router, then the all parameter can be used.

     [edit protocols rsvp]  lab@Chicago#set interface all 
  3. Once RSVP has been enabled, it is possible to verify a configuration with the following show commands from operational mode:

    • show rsvp neighbor ” displays a summary list of the router's RSVP neighbors

       lab@Chicago# run show rsvp neighbor  RSVP neighbor: 1 learned Address  Idle Up/Dn LastChange HelloInt  HelloTx/Rx  MsgRcvd Status 10.0.0.1   5   1/0     49:43      3         971/971     47 

      Note ”

      Remember that JUNOS allows operational-mode commands to be executed while still in configuration mode by using the run command.


    • show rsvp interface ” This command displays a summary list of the router interfaces configured for RSVP, the state of the interface, and resource information.

       lab@Chicago# run show rsvp interface  RSVP interface: 3 active                                                                    High-                    Active  Subscr-  Static    Available  Reserved  water Interface   State  resv    iption   BW        BW         BW        mark fxp0.0        Up    0      100%    100Mbps    100Mbps    0bps      0bps fe-1/0/3.0    Up    0      100%    100Mbps    100Mbps    0bps      0bps at-1/2/1.100  Up    1      100%    155.52Mbps 155.52Mbps 0bps      0bps 
    • show rsvp interface detail ” This command provides a more in-depth look at the RSVP functionality and keeps track of the different types of RSVP messages. This can be a useful command to determine if the RSVP messages are being exchanged properly.

       lab@Chicago#  show rsvp interface detail  RSVP interface: 3 active at-1/2/1.100  Index 6, State Ena/Up, ActiveResv 1, PreemptionCnt 0   NoAuthentication, NoAggregate, NoReliable, HelloInterval 3(second)   Address 10.0.0.2, 192.168.5.1   Subscription 100%, StaticBW 155.52Mbps, AvailableBW 155.52Mbps   ReservedBW [0] 0bps[1] 0bps[2] 0bps[3] 0bps[4] 0bps[5] 0bps[6] 0bps[7] 0bps   PacketType              Total                  Last 5 seconds                    Sent      Received        Sent      Received   Path               35            38           0             0   PathErr             0             0           0             0   PathTear            0             1           0             0   Resv               38            35           0             0   ResvErr             0             0           0             0   ResvTear            0             0           0             0   Hello            1175          1175           1             1   Ack                 0             0           0             0   Srefresh            0             0           0             0 
    • show rsvp session ” This command displays information about the RSVP session to include the name of the LSP being used to transport the packets.

    • show rsvp session detail ” This command provides a detailed look at the RSVP sessions configured on the router. It is useful for checking how RSVP information is being exchanged between RSVP neighbors.
