2 variables in config change template for juniper MX

Hello Guys,

I have created a config change template to automate creation of VRFs on my juniper MX

@INTERFACE_IP_ADD.@VLAN_ID

Above are 2 variables seperated by a dot. For example , lets say my interface is ge-1/1/1 and the vlan ID is 2000( @INTERFACE_IP_ADD = ge-1/1/1 and @VLAN_ID=2000)

So my expected output should be ge-1/1/1.2000. Unfortunately , this dot is causing the scrip to break. Any ideas how i can declare those 2 variables seperated by a dot.

As a temporary workaround i configured the below ( without a dot)

@INTERFACE_IP_ADD@VLAN_ID

Then when i enter the interface ID , i enter it like follows : ge-1/1/1.

Unfortunately this is causing the template to be too long and causing confusion for NOC team.

Any ideas how i can permanently solve this?

Below are my variables:

(

                                           NCM.Nodes @ContextNode,

                                           string @Physical_Interfaces,

                                           string @Interface_Description,

                                           string @INTERFACE_IP_ADD,

                                           string @VRF_NAME,

                                           string @VLAN_ID,

                                           string @BGP_GROUP_NAME,

                                           string @BGP_PEER

  )

Thank you
