Problem Facing to set as-number in vpn l3vpn (for example vpn l3vpn volvo) in Managing Network Services Chapter 5 - Running an example

[samya.ghosh]

Dear All,

I am trying to run an example in Managing Network Services Chapter 5 - NSO_getting_Started.

The example running well until vpn l3vpn configuration with as-number 65101.

i am using Ubuntu - Unix .

here is my command line scenario....

********************************************************************************************************************************************

admin@ncs# devices sync-from

sync-result {

    device ce0

    result true

}

sync-result {

    device ce1

    result true

}

sync-result {

    device ce2

    result true

}

sync-result {

    device ce3

    result true

}

sync-result {

    device ce4

    result true

}

sync-result {

    device ce5

    result true

}

sync-result {

    device ce6

    result true

}

sync-result {

    device ce7

    result true

}

sync-result {

    device ce8

    result true

}

sync-result {

    device p0

    result true

}

sync-result {

    device p1

    result true

}

sync-result {

    device p2

    result true

}

sync-result {

    device p3

    result true

}

sync-result {

    device pe0

    result true

}

sync-result {

    device pe1

    result true

}

sync-result {

    device pe2

    result true

}

sync-result {

    device pe3

    result true

}

admin@ncs# config

Entering configuration mode terminal

admin@ncs(config)# vpn l3vpn volvo

admin@ncs(config-l3vpn-volvo)# as-number 65101

-------------------------------^

syntax error: unknown command

Always facing this problem with that as-number command & when I configure the l3vpn without as-number or set as-number inside config-endpoint-main-­office I get error during commit dry-run outformat native.

Here is my scenario ...

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

admin@ncs(config)# commit dry-run outformat native

Aborted: 'vpn l3vpn volvo route-distinguisher' is not configured

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Here is the command documentation from cisco getting stated....

ncs# config

Entering configuration mode terminal

ncs(config)# vpn l3vpn volvo

ncs(config-l3vpn-volvo)# as-number 65101

ncs(config-l3vpn-volvo)# endpoint main-office

ncs(config-endpoint-main-office)# ce-device ce0

ncs(config-endpoint-main-office)# ce-interface GigabitEthernet0/11

ncs(config-endpoint-main-office)# ip-network 10.10.1.0/24

ncs(config-endpoint-main-office)# bandwidth 12000000

ncs(config-endpoint-main-office)# !

Hi Samya,

I believe the documentation might not be inline with the code in the examples directory.

Looking at the YANG code on NSO 4.4.2, I see that the as-number parameter is associated with each endpoint, rather than being a global parameter on the service. This means that each of your endpoints should have this value provided.

so instead of providing this value at this stage, you will have to provided it for each endpoint.

For example,

ncs(config-l3vpn-volvo)# endpoint main-office

ncs(config-endpoint-main-office)# as-number 65101

The reason you are getting the error upon commit is because the VPN also includes a mandatory value called route-distinguisher which might be missing from the documentation:

leaf route-distinguisher {

  description "Route distinguisher/target identifier unique for the

  VPN";

  mandatory true;

  type uint32;

}

so, you'll have to also provide this value - unsigned 32 bits integer

For example, before you provide your endpoint details you can provide value for this field:

ncs(config)# vpn l3vpn volvo

ncs(config-l3vpn-volvo)# route-distinguisher 123456

generally speaking, the error you got there suggests that a mandatory value is missing, so you can try using tab completion or '?' in CLI to try to get some hints for the values that are available for you to provide.

Hope that helps,
