[c-nsp] MPLS TE conver from IOS to IOS-XR

[许虎]

Hi Team,

We had four 7609-S which they run mpls te with each other, now we upgrade
one 7609-S to ASR9k platform.
The topology as bellow:

7609-1-------------7609-2
     |                                |
     |                                |
7609-3-------------ASR9K

In the old platform 7609-s, the mpls related configuration as bellow:

mpls traffic-eng tunnels
mpls traffic-eng auto-tunnel backup
mpls traffic-eng auto-tunnel backup config unnumbered-interface Loopback0
mpls traffic-eng auto-tunnel backup tunnel-num min 2001 max 3000
mpls traffic-eng auto-tunnel mesh
mpls traffic-eng auto-tunnel mesh tunnel-num min 1001 max 2000
mpls label protocol ldp

interface Auto-Template1
ip unnumbered Loopback0
mpls ip
mpls label protocol ldp
mpls mtu 17916
tunnel mode mpls traffic-eng
tunnel destination access-list 1
tunnel mpls traffic-eng autoroute announce
tunnel mpls traffic-eng path-option 1 dynamic
tunnel mpls traffic-eng fast-reroute

access-list 1 permit 192.168.233.1

interface ten 3/2.1700
mpls ip
mpls traffic-eng tunnels

router ospf 100
mpls traffic-eng router-id Loopback0
mpls traffic-eng area 0.0.0.0

I had one questions, in the IOS-XR, I didn’t find any configuration about
the auto-mesh or auto-template configuration example, is anyone know how to
configure?

Many thanks,
Hu Xu
