Dear All,
I would be really grateful if someone could suggest or
propose any config for implementing QOS for MPLS VPNs.
I have the following scenario:
CE1 -->PE1-->PE2-->CE2
I understand that it is possible to mark and match DSCP and MPLS EXP bits as
follows:
DSCP (CE1)-->EXP(PE1)--->EXP(PE2)--->DSCP(CE2)
I am being able to match DSCP bits from CE on PE and apply whatever policing
required.
I can also set MPLS EXP bits on PE according to matched DSCP bits from CE.
What I have not being able to understand is how my set MPLS EXP bits will be
carried to the other PEs ?
Will I need to apply any service policy to carry MPLS EXP bits from PE to
the other ?
Regards,
Zahid
