Hello,

Here is a ping result with monitor traffic activated on xe-3/1/0.
I Ping the other CE and it seems that the ping leaves the Juniper interface:

I also create an extended access list on CE2  and debub ip packet detail 199

#sh ip access-lists 199
Extended IP access list 199
    10 permit icmp host 150.1.1.2 host 150.1.1.1
    20 permit icmp host 150.1.1.1 host 150.1.1.2 (6 matches)

The ICMP echo requests from Juniper does not arrive at Cisco and also I ping
from Cisco CE2 to Juniper CE1 and i have encapsulation failed because it
dows not learn arp from Juniper:
