[j-nsp] MX5 rewrite-rules

[Mihai]

Hello,

  I have a very basic setup involving 1 x C7600 and 1 X MX5T and I want 
to rewrite all the dscp/inetprec marking received on MX5 from C7600 to 
dscp/inetprec 0.
The topology is this: C7600 vlan887 gi9/44 -  ge-1/0/0.887 MX5 
virtual-router C -  ge-1/0/3.200 ->  ge-1/1/3.200 R1 logical-system.

mx5t# show routing-instances customer1
instance-type virtual-router;
interface ge-1/0/0.887;
interface ge-1/0/3.200;

mx5t# top show interfaces ge-1/0/0.887
vlan-id 887;
family inet {
     filter {
         input test;
     }
     address 192.168.200.102/30;
}

top show interfaces ge-1/0/3.200
vlan-id 200;
family inet {
     address 172.27.0.30/30;
}


top show logical-systems r1 interfaces ge-1/1/3.200
description r1-c;
vlan-id 200;
family inet {
     address 172.27.0.29/30;
}

mx5t# top show logical-systems r1 interfaces lo0
unit 1 {
     family inet {
         address 172.27.255.1/32;
     }
}


show class-of-service interfaces ge-1/0/3
unit 200 {
         rewrite-rules {
         ieee-802.1 default;
         inet-precedence default;
     }
}

mx5t# top show firewall family inet filter test
term 1 {
     then {
         loss-priority low;
         forwarding-class best-effort;
     }
}


An icmp packet with tos2 sent from Cisco to R1 lo0.1 arrives with the 
same value on interface ge-1/1/3.200 and I can't understand why:

12:36:15.147992  In IP (tos 0x2,ECT(0), ttl 254, id 13900, offset 0, 
flags [none], proto: ICMP (1), length: 100) 192.168.200.101 > 
172.27.255.1: ICMP echo request, id 44441, seq 0, length 80


Any advice?
