Traffic engineering service model

Etts Equinox — Fri, 01 Mar 2019 11:57:15 GMT

I have been trying to create a service model for TE explicit path but what happens is that the xml merges ip addresses together and the only solution, i know is to repeat the xml like the l2vpn model but it looks illogical for me because i have no idea how many indexes that customer will create so my question is there any solution without repeating the xml manually?

admin@ncs(config)# show configuration

devices device pe0

config

cisco-ios-xr:explicit-path name xxx

index 1 next-address ipv4 unicast 3.3.3.3

index 2 next-address ipv4 unicast 4.4.4.4

Yang

=================

module TE {

namespace "http://com/example/TE";

prefix TE;

import ietf-inet-types { prefix inet; }

import tailf-ncs { prefix ncs; }

import tailf-common { prefix tailf; }

import ietf-yang-types { prefix yang-type; }

augment /ncs:services {

list TE {

key device;

uses ncs:service-data;

ncs:servicepoint "TE";

leaf device {

tailf:info "PE Router";

container Explicit-path {

when "../Explicit='true'";

list ex-name {

key name;

leaf name {

type string;

}

list PATH {

key number;

leaf number {

type uint32;

}

leaf option {

type enumeration {

enum loose;

enum strict;

}

leaf ip-add {

type inet:ipv4-address;

}

===================================

XML

=======

?xml version="1.0" encoding="utf-8"?>

<config-template xmlns="http://tail-f.com/ns/config/1.0" servicepoint="TE">

<name>{/device}</name>

<explicit-path xmlns="http://tail-f.com/ned/cisco-ios-xr">

<name>

<pathname>{/Explicit-path/ex-name/name}</pathname>

<index>

<index-id>{/Explicit-path/ex-name/PATH/number}</index-id>

<keyword>next-address</keyword>

<ipv4>

<unicast>{/Explicit-path/ex-name/PATH/ip-add}</unicast>

</ipv4>

</index>

</name>

</explicit-path

Hi,

The the attribute foreach may solve your problem.

You should check the "Loop Statement" section in the NSO developement guide.
