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 routeForIPv6 host1(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 75 host1(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 red host1(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
                                     ------ -----
   IPv6 Policy routeForIPv6
      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 epIPv6 host1(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)#exit host1(config-policy-list)#exit host1(config)#
5. Display the policy list.

   host1#show policy-list epIPv6
   

                                     Policy Table
                                     ------ -----
   IPv6 Policy epIPv6
      Administrative state: enable
      Reference count:      0
      Classifier control list: *, precedence 100
         exception http-redirect
