[j-nsp] QoS - Mapping between EXP and IP Prec.

[Varaillon Jean Christophe]

Hi,

 

>From Cisco I remember that when an IP packet is labeled, the IP precedence
value is copied into MPLS experimental bits.

 

Is Juniper behaving the same way?

 

If so, why, for a identical bit pattern (e.g. 101) both MPLS EXP and IP
Precedence do not point to the same alias (e.g. ef)?

 

@M10i-re0> show class-of-service code-point-aliases exp

Code point type: exp

  Alias              Bit pattern
