This chapter provides information for configuring policy lists on E Series Broadband
Services Routers. See the E120 and E320 Module Guide for modules supported on the
E120 and E320 Broadband Services Routers. The chapter discusses the following topics:
Policy Lists Overview on page 15
Creating Policy Lists for ATM on page 17
Creating Policy Lists for Frame Relay on page 19
Creating Policy Lists for GRE Tunnels on page 20
Creating Policy Lists for IP on page 21
Creating Policy Lists for IPv6 on page 22
Creating Policy Lists for L2TP on page 24
Creating Policy Lists for MPLS on page 24
Creating Policy Lists for VLANs on page 25
You create a policy rule by specifying a policy action within a classifier group that
references a CLACL. These rules become part of a policy list that you can attach to an
interface as either an input policy, secondary-input policy, or output policy. The router
applies the rules in the attached policy list to the packets traversing that interface.
You can apply policy lists to packets:
Arriving at an interface (input policy); on IP and IPv6 interfaces the packets arrive before
route lookup
Arriving at the interface, but after route lookup (secondary input policy); secondary
input policies are supported only on IP and IPv6 interfaces
Leaving an interface (output policy)
Figure 1 on page 16 shows how a sample IP policy list is constructed.
