XML template Change Command Sequence

[bjronmork]

Our New Service implementation is working fine and push configurations rightly; but We are facing command sequence issue while making changes; for example as per below config Cisco NSO generates configurations command (which are all fine) but sequence is not correct and we face issues in implementation. 

root@ncs(config-link-ORA01/01)# commit dry-run outformat native 
native {
    device {
        name ORA01
        data interface GigabitEthernet0/0/5
              no description
              no ip address
              service instance 25 ethernet
               description Changing to Tagged
               encapsulation dot1q 25
               rewrite ingress tag pop 1 symmetric
               bridge-domain 25
              exit
              no ip vrf forwarding NDS_NEW_SER
              no ip address
             exit
             interface BDI25
              description   Changing to Tagged
              ip vrf forwarding NDS_NEW_SER
              ip address 12.34.45.1 255.255.255.252
              load-interval 30
              no shutdown
             exit
             router ospf 3535 vrf NDS_NEW_SER
              passive-interface GigabitEthernet0/0/5
              no passive-interface BDI25
             exit
    }
}

we have below error

root@ncs(config-link-ORA01/01)# commit
Aborted: External error in the NED implementation for device ORA01: command: passive-interface GigabitEthernet0/0/5: %Interface specified does not belong to this process

but the correct sequence tested on device is ;

(1)
             router ospf 3535 vrf NDS_NEW_SER
              passive-interface GigabitEthernet0/0/5
(2)
interface GigabitEthernet0/0/5
  no description
  no ip address
  service instance 25 ethernet
   description Changing to Tagged
   encapsulation dot1q 25
   rewrite ingress tag pop 1 symmetric
   bridge-domain 25
  exit
  no ip vrf forwarding NDS_NEW_SER
  no ip address
exit
interface BDI25
  description   Changing to Tagged
  ip vrf forwarding NDS_NEW_SER
  ip address 12.34.45.1 255.255.255.252
  load-interval 30
  no shutdown
exit
(3)
             router ospf 3535 vrf NDS_NEW_SER
              no passive-interface BDI25
             exit

NSO version 4.7.3.1

NED version 6.15.1

Please suggest how to change sequence...

You should raise a ticket for this, to get a NED change.

But, for information: The sequence is controlled through annotations in the YANG module, you can open it and look around if you are interested. The annotations are documented in the manpage tailf_yang_cli_extensions.

tailf_yang_cli_extensions is a big list. What exactly i should used to make command sequence; please highlight some extension or if any example is available pls share. Thanks

You really should write a ticket.

But, in this case it looks like you want a dependency between router ospf X vrf Y and ip vrf forwarding Y under an interface. So we are looking at either tailf:cli-diff-dependency or a tailf:non-strict-leafref (from tailf_yang_extensions), I think. I know there are examples of this in the NED already. If you are just hacking, put a tailf:cli-diff-dependency from interface to router or something like that – no need to be fine grained if you are just proving a point.
