Hi,
Can any one support me to find out what can i do to let this l2vpn work as expected .
let me share with you my topolgy and configuration .
[R14-CE]-pos1/0<---------PPP--------->pos2/0[PE-R13]<----->[P]<----->[P]<------->[PE-R15]s3/1<---------FR--------->s0/1[CE-R18]
Nodes and used interfaces as shown , for L2vpn interworking between PPP and FR.
Configuration :
==========
R14#
=====
interface POS1/0
mtu 1500
ip address 2.2.2.1 255.255.255.0
encapsulation ppp
R13:
====
pseudowire-class INTER-PPP-FR
encapsulation mpls
interworking ip
interface POS2/0
mtu 1504
no ip address
encapsulation ppp
xconnect 15.15.15.15 1315 pw-class INTER-PPP-FR
R15:
===
pseudowire-class Inter
encapsulation mpls
interworking ip
interface Serial3/1
mtu 1504
no ip address
encapsulation frame-relay
load-interval 30
serial restart-delay 0
frame-relay intf-type dce
connect FR-2-FR Serial3/1 101 l2transport
xconnect 13.13.13.13 1315 pw-class Inter
R18:
===
interface Serial0/1
ip address 2.2.2.2 255.255.255.0
encapsulation frame-relay
serial restart-delay 0
The above topology has been deployed using GNS3 with 7200 routers with IOS
Version 12.2(33)SRE9
Tests:
====
1- Ping failed , no arp resolution successed
2-Resulting of my troubleshooting , ATOM is UP as below log shown .

Remote interface description:
Sequencing: receive disabled, send disabled
Control Word: On (configured: autosense)
VC statistics:
transit packet totals: receive 0, send 20
transit byte totals: receive 0, send 2520
transit packet drops: receive 0, seq error 0, send 0
so i tried debug mpls packets in the core to check label traffic through core network , i found that R14-CE1 send ICMP packet to the connected edge R13 then it forwarded normally through the core untill reached CE2 then , the reply on this packet towards the originator from CE2 forwarded from connected Edge towards core network with one label [ PW Label ] only , no AC Label. so traffic get dropped when reached the orginator CE's connected Edge.
Can any support what can i do or if there are any missing configurations ???
Thank you
Mohamed
