Thanks dear
I have removed the below lines

R2 (CE connected to Cisco)
R2#sh ip arp
Protocol  Address          Age (min)  Hardware Addr   Type   Interface
Internet  192.168.23.2            -   c202.1a7c.0000  ARPA   FastEthernet0/0.23
Internet  192.168.23.3            0   Incomplete      ARPA

R3#sh ip arp
Protocol  Address          Age (min)  Hardware Addr   Type   Interface
Internet  192.168.23.2            0   c202.1a7c.0000  ARPA   FastEthernet0/0.23
Internet  192.168.23.3            -   c203.247c.0000  ARPA   FastEthernet0/0.23

Could that be MTU related?

I did this for about 1200 Nodes and had no issue But on an actual box(M20). Anyway this may be related to GNS3 and emulation. Also we don’t use following line:  set protocols l2circuit neighbor 1.1.1.1 interface em1.23 encapsulation-type ethernet-vlan
set protocols l2circuit neighbor 1.1.1.1 interface em1.23 ignore-encapsulation-mismatch
set protocols l2circuit neighbor 1.1.1.1 interface em1.23 ignore-mtu-mismatch

The first three line is enough. This also can be related to VLAN rewrite section. Do you have traffic in one direction? I mean for example do you have ARP entry from Source IP address on destination device?Getting a PCAP file is also useful.   From: Mohammad Khalil [mailto:eng_mssk at hotmail.com]

I have added the no-control-word on Juniper and changed the xconnect on Cisco (i was already doing that , but I made the pseduwire to manipulate the parameters)

Still no luck > From: soltanian at gmail.com
