Hello, Are you trying to rewrite the MPLS header and IP header inside the MPLS packet? I think you can do this. See:
http://www.juniper.net/techpubs/en_US/junos10.2/information-products/topic-collections/config-guide-cos/topic-27835.html#id-11667692 Serge ----- Original Message ---- From: Luca Tosolini <[email protected]> To: Lista-Juniper <[email protected]> Sent: Mon, September 6, 2010 1:37:54 PM Subject: [j-nsp] compound rewrite-rule Experts, on Mx and Junos 10.2R2.11 the following rewrite-rules configuration: show configuration class-of-service interfaces xe-4/1/0 unit 0 { classifiers { exp MPLS; ieee-802.1 DOT1P; inet-precedence TOS; } rewrite-rules { exp MPLS-RW; ieee-802.1 DOT1P-RW; inet-precedence TOS-RW; } } It looks like only one of the rewrite is executed but not all of them; see the following capture of an egress frame: sudo tcpdump -i eth1 -n -v -c1 mpls tcpdump: WARNING: eth1: no IPv4 address assigned tcpdump: listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes 16:12:14.043480 MPLS (label 0 (IPv4 explicit NULL), exp 6, [S], ttl 62) IP (tos 0x0, ttl 63, id 0, offset 0, flags [none], proto UDP (17), length 114) Here exp=6 and tos=0 so for an MPLS packet only MPLS-RW is executed. Instead on a IP frame I see that TOS-RW is executed. So it looks that the rewrite-rules are NOT executed together on same frame !! Is this the wanted behavior?
