Omar, What traffic do you expect to be marked with EXP 6?
Do you have any transit traffic (i.e. traffic not originated by the 7600, but sent from a remote client), which is marked with some other (non EXP=6,0) value? Usually Prec 6 would be used for control traffic (routing protocols etc), and this traffic is usually one hop only, and would not be encapsulated with MPLS, so no EXP bits... The only exceptions I can think of would be transit BGP or directed LDP sessions terminated on a remote router (not the adjacent CRS) Arie -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of omar parihuana Sent: Thursday, August 25, 2011 02:08 To: Leonardo Gama Souza Cc: [email protected] Subject: Re: [c-nsp] QoS VLAN Marking is not working 7600 Leonardo, Thank you for your answer, there is enable MPLS between CRS and 7600. however, the PFC used is PFC3B. please do you have any doc regarding: "Moreover only PFC3C/PFC3CXL supports ingress EXP marking at ip2mpls." ? I'm reading http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/gu ide/mplsqos.html#wp1531487 I didn't find details about the "EXP Marking at ingress". Rgds.
