Mpls Qos Configuration Example; Qos Configuration For Streams In The Same Vpn - 3Com 3C13636 Configuration Manual

Configuration Guide
Perform the following configurations in interface view.
Table 6-12 Apply TP policy on the interface and label MPLS packets
Operation
Apply TP policy on the

MPLS packets
Remove

action can be
remark-mpls-exp-continue new-mpls-exp: Configures the new MPLS EXP value,
new-mpls-exp, and continue to be processed by the next CAR policy, ranging from
0 to 7.
remark-mpls-exp-pass new-mpls-exp: Configures the new MPLS EXP value,
new-mpls-exp, and send the packet to the destination, ranging from 0 to 7.
EXP domain of the MPLS packet can only be set on the inbound interface of the PE. If
in the input direction is IP packet, but is encapsulated as MPLS packet in the output
direction, the configured TP policy has taken effect.
When setting the EXP domain of the MPLS packet, two layers of labels shall be set and
ToS domain in the IP header shall not be modified.

6.3 MPLS QoS Configuration Example

6.3.1 QoS Configuration for Streams in the Same VPN

I. Network requirements
In the network diagram, CE1 and CE2 belong to VPN1; the bandwidth of the PE1-P link
and P-PE2 link is 2M. Define different QoS guarantee levels for the streams with
different priority levels in the VPN1.
The configuration in this example includes these two parts:
First, configure MPLS VPN on the CE1, PE1, P, PE2 and CE2.
Run OSPF between PE1, P and PE2
Create MP-EBGP neighbors between PE and CE
Create MP-IBGP neighbors between PEs
Second, configure MPLS QoS on the PE1 and P.
Configure QoS policy on the ingress interface Ethernet1/1/0 on the PE1 and set
EXP domain value according to the DSCP attribute of MPLS packets.
