[Problem Description]

redirect the traffic received on internet-port inbound from MPLS to Huawei L3

[Problem Analysis]

answer for customer

[Root Cause] 

answer for PBR policy

[Solution Description]

1、define traffic classifier the name is A1

[Switch] traffic classifier A1
[
Switch-classifier-c1] if-match any (any is match all packets， you can define ACL to match the packets that you want )

 

[SwitchA-classifier-c1] quit

2、Configure a traffic behavior to redirect matching traffic to the firewall (next hop address 172.29.145.185).

[Switch] traffic behavior A1
[Switch-behavior-b1] redirect ip-nexthop 172.29.145.185
[Switch-behavior-b1] quit

3、Configure a traffic policy

[Switch] traffic policy p1
[
Switch-trafficpolicy-p1] classifier A1 behavior A1
[
Switch-trafficpolicy-p1] quit

4、Apply the traffic policy to INTER-inbound

 on Switch in the inbound direction.

[Switch]interface inter-inbound

[Switch-[Internet inbound] traffic-policy p1 inbound
[Switch-GigabitEthernet0/0/1] quit
[Switch] quit

PBR is usual method to redirect the traffic, and we always configure traffic-policy with redirect behaviour to do this.
Run the display ip policy-based-route command to check enabled PBR policies.
Run the display policy-based-route [ policy-name ] command to check the created policy content.

"Incoming" refers to packets which originate elsewhere and arrive at the machine, while "outgoing" refers to packets which originate at the machine and arrive elsewhere

PBR is implemented through redirection in Modular QoS Command-Line Interface (MQC). Configure a traffic classifier to classify data packets, and then configure a traffic behavior to redirect packets matching traffic classification rules. Configure a traffic policy, bind the traffic behavior and traffic classifier to it, and apply the traffic policy to an interface. As shown in the right figure, PBR is configured to redirect packets from VLAN 100 to RouterA. Before PBR is configured, all packets pass through RouterB.
