Please check attached document ....Our requirement is
Requirement : Drop tagged data (200,300,400) coming from ASR9000 to respective ASR920 (a,b,c) respectively by using EoMPLS L2VPN .
Configuration Steps:
1) Service instance are created on ASR 907 ,as Router ASR 907 will see vlan tag attached and will send to respective instance configured on ASR 920 , Service instance are created on destination ASR920 respectively .
2) Uplink on ASR 9000 toward ASR907 is configured as sub interface with Vlan 200,300,400 .
3) Loopback are configured on each ASR .
4) IGP (OSPF with MPLS LDP is configured between internal Ring from 920a to 920c).
4) Configuration on ASR 907 a and ASR 907 b for Service instance are

Confusion point : Do I need to add "rewrite ingress tag pop 1 symmetric"
Please check and reply ......your prompt guide will be appreciated.
