Routing

Hi All,

I'm try to configure the SNMP for just logical system only. I refer to this URL  below. But i'm still dont understand why we still need put routing-instances? Appreciate some one feedback or sample config example.

Thanks

community R1-Sun {
    routing-instance SNMP-ONLY;
    ##
    ## Warning: [routing-instance] must be configured for this logical-system
    ##
    logical-system R1-Sun;

Hi kronicklez,

The "routing-instance" knob will provide the user with flexibility of SNMP client access to whole logical-system or paritial restricted acess only to a particular routing-instance.

In case, you would like to provide access to whole logical-system, the routing-instance has to be set to "default"

show snmp community surya
logical-system LR1 {
    routing-instance default;
}

And if you want to restrict to particular a routing-instance within logical-system, then it would be just that routing-instance name.

show snmp community surya
logical-system LR2 {
    routing-instance FED;
}

Of course you should have trhe corresponding routing-instance configured under the logical-system, else the commit would fail like below:

{master}[edit]
suryak@MX960# commit
re0:
error: The routing instance(LR1/FED) is not configured
error: configuration check-out failed

Hi Surya,

Thanks for your feedback. Another question related to SNMP for logical system.

If i just put OID as per below config on the router is it by default will exclude other OID. What i mean is it behaviour like policy statement will reject by default.

Thanks and appreciate your feedback.

With above config, you will be able to poll only the OID under "System" hierarchy. All other OIDs out of this range will be returned with empty value.

If I have answered your query, please accept this as "Solution". Kudos are also welcomed
