    Creating Policy Lists for IPv6

    The following example creates an IPv6 policy list named routeForIPv6. For information about creating the CLACL used in this example, see the previous sections.

    1. Create the policy list routeForIPv6.
      host1(config)#ipv6 policy-list routeForIPv6host1(config-policy-list)#
    2. Create the classification group for the CLACL named ipv6tc67 and assign the precedence to the classification group.
      host1(config-policy-list)#classifier-group ipv6tc67 precedence 75host1(config-policy-list-classifier-group)#
    3. Add a rule to color packets as red, and a second rule that sets the traffic class field of the packets to 7.
      host1(config-policy-list-classifier-group)#color redhost1(config-policy-list-classifier-group)#mark tcfield 7
    4. Add a rule that specifies a group of forwarding solutions based on classifier control list ipv6tc67.
      host1(config-policy-list-classifier-group)#forward next-hop 3001:82ab:1020:87ec::/64 order 10 host1(config-policy-list-classifier-group)#forward next-hop 2001:82ab:1020:87ec::/64 virtual-router vr1 ignore-default-route order 20
    5. Exit Policy List Configuration mode to save the configuration.
      host1(config-policy-list-classifier-group)#exit host1(config-policy-list)#exit host1(config)#
    6. Display the policy list.
      host1#show policy-list routeForIPv6
      
                                        Policy Table
                                        ------ -----

         Administrative state: enable
         Reference count:      0
         Classifier control list: C1, precedence 90
         Classifier control list: ipv6tc67, precedence 75
            forward
               Virtual-router: default
               List:
                 next-hop 3001:82ab:1020:87ec::/64, order 10, rule 2 (active)
               Virtual-router: vr1
               List:
                 next-hop 2001:82ab:1020:87ec::/64, ignore-default-route, order 20, rule 3 
            color red
            mark tc-precedence 7 

    You use the exception http-redirect command to create an exception rule within a policy classifier group to specify the client application for the destination of packets rather than forwarding them using the forwarding controller (FC).

    In lower-numbered releases, the exception http-redirect command only supported the creation of exception rules within IPv4 policy lists. You can now configure the exception http-redirect command to create exception rules within IPv4 and IPv6 policy lists.

    The following example creates an IPv6 policy list, epIPv6 for the http-redirect exception:

    1. Create the policy list epIPv6.
      host1(config)#ipv6 policy-list epIPv6host1(config-policy-list)#
    2. Create the classification group to match all packets.
      host1(config-policy-list)#classifier-group *host1(config-policy-list-classifier-group)#
    3. Create an exception policy for http-redirect.
      host1(config-policy-list-classifier-group)#exception http-redirect
    4. Exit Policy List Configuration mode to save the configuration.
      host1(config-policy-list-classifier-group)#exithost1(config-policy-list)#exithost1(config)#
    5. Display the policy list.
      host1#show policy-list epIPv6
      
                                        Policy Table
                                        ------ -----

         Administrative state: enable
         Reference count:      0
         Classifier control list: *, precedence 100
            exception http-redirect
