[j-nsp] SNMP polling a logical-system without encoding it asLS/RI at community

[Subodh Kumar]

It would depend on which interface is your packet entering the system
(router).  Consider an example:

            ________                    _________
           |       |                    |       |
           |       |      (lr1/ri2)     |       |
           |   R1  |--------------------| nms1  |
           |       |fe-0/0/3        em1 |       |
           |_______|                    |_______|      


   - (lr1/ri2) indicate the routing-instance
   - Ip Address:
        nms1 (em1): 14.14.14.1


logical-systems lr1 {
   routing-instances {
      ri2 {
             ...
             interface fe-0/0/3;
             ...
      }
   }
   interfaces{
      fe-0/0/3 {
           unit 0 {
             family inet {
                address 14.14.14.2/24;
             }
         }
      }
      lo0 {
        unit 1 {
           family inet {
               address 14.14.14.100/32
           }
        }
      }
   }
}


Now if you send a SNMP packet from 'nms1' on ip-addess 14.14.14.100 or
14.14.14.2, that makes sure that packet is entering the system from
inetrafce fe-0/0/3 which is part of logical-systems 'lr1'. In this case
you don't need to specify the prefix 'lr1/default' in the community
string.

In your case, it looks that the SNMP packet is getting into the router
through 'fxp0' or some interface that is part of 'default'
routing-instance. Does the 'ping 10.0.0.5' from the NMS work for you?
