    Verifying That Virtual Routing Instances Are Working

    Purpose

    After creating a virtual routing instance, make sure it is set up properly.

    Action

    1. Use the show route instance command to list all of the routing instances and their properties:
      user@switch> show route instance
      Instance             Type
               Primary RIB                                     Active/holddown/hidden
      master               forwarding
               inet.0                                          3/0/0
      
      __juniper_private1__ forwarding
               __juniper_private1__.inet.0                     1/0/3
      
      __juniper_private2__ forwarding
      
      instance1            forwarding
      
      r1                   virtual-router
               r1.inet.0                                       1/0/0
      
      r2                   virtual-router
               r2.inet.0                                       1/0/0
      
    2. Use the show route forwarding-table command to view the forwarding table information for each routing instance:
      Routing table: r1.inet
      Internet:
      Destination        Type RtRef Next hop           Type Index NhRef Netif
      default            perm     0                    rjct   539     2
      0.0.0.0/32         perm     0                    dscd   537     1
      103.1.1.0/24       ifdn     0                    rslv   579     1 ge-0/0/3.0
      103.1.1.0/32       iddn     0 103.1.1.0          recv   577     1 ge-0/0/3.0
      103.1.1.1/32       user     0                    rjct   539     2
      103.1.1.1/32       intf     0 103.1.1.1          locl   578     2
      103.1.1.1/32       iddn     0 103.1.1.1          locl   578     2
      103.1.1.255/32     iddn     0 103.1.1.255        bcst   576     1 ge-0/0/3.0
      224.0.0.0/4        perm     0                    mdsc   538     1
      224.0.0.1/32       perm     0 224.0.0.1          mcst   534     1
      255.255.255.255/32 perm     0                    bcst   535     1

    Meaning

    The output confirms that the virtual routing instances are created and the links are up and displays the routing table information.
