You can define the flow template by means of the IP + VLAN + DMAC method to 
make sure that different kinds of packets are processed in different ways:

■

If ARP packets do not match IP rules in redirection, they will be processed on 
the non-MPLS card;

■

If Layer 2 traffic does not match DMAC in redirection, it will be L2-forwarded 
on the non-MPLS card;

■

If Layer 3 packets (including unicast protocol packets) match the rule, they will 
be redirected to the MPLS card.

Refer to section "QACL" and the following networking example in the manual for 
detailed information on configuring flow template and ACL rules.

The traffic-redirect command is used to enable ACL flow classification and 
redirect the packets (only applicable to the rules whose action is permit in the 
ACL). There are two kinds of redirection commands:

■

Redirect packets to a port: You can redirect packets received by the source port 
of the non-MPLS card to the specified destination port of the MPLS card.

■

Redirect packets to an application module: You can redirect packets received by 
the source port of the non-MPLS card or MPLS card to the VPLS card.

There are two kinds of redirection services:

■

VPLS-related redirection services: The key word join-vlan must be specified, 
and the system will add the current port into destination-vlan after the 
redirection enabled; when redirection is disabled, the system will log the 
current port out of the VLAN if what is deleted is a join-vlan enabled 
redirection in the VLAN.

■

MPLS-independent redirection services: Such redirection services include URPT, 
reflexive ACL, BT traffic control and so on. join-vlan cannot be enabled in such 
a service. The port will not be added into VLAN when redirection is configured, 
and the port will not be removed from the VLAN when redirection is deleted.
