19.3 PBR Examples
Example 1:
On port ethernet 1/1, set the messages whose source IP is within the segment 2000:: /64 to do policy routing,
the next hop is 3100::2.
The following is the configuration steps:
Switch#config
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ipv6 address 2000::1/64
Switch(Config-if-Vlan1)#ipv6 neighbor 2000::2 00-00-00-00-00-01 interface Ethernet 1/1
Switch(config)#interface vlan 2
Switch(Config-if-Vlan2)#ipv6 address 3000::1/64
Switch(Config-if-Vlan2)#ipv6 neighbor 3000::2 00-00-00-00-00-02 interface Ethernet 1/2
Switch(config)#interface vlan 3
Switch(Config-if-Vlan3)#ipv6 address 3100::1/64
Switch(Config-if-Vlan3)#ipv6 neighbor 3100::2 00-00-00-00-00-03 interface Ethernet 1/5
Switch(config)# ipv6 access-list extended b1
Switch(Config-IPv6-Ext-Nacl-b1)# permit tcp 2000:: /64 any-destination
Switch(Config-IPv6-Ext-Nacl-b1)#exit
Switch(config)#mls qos
Switch(config)#class-map c1
Switch(config-ClassMap)#match ipv6 access-group b1
Switch(config-ClassMap)# exit
Switch(config)#policy-map p1
Switch(config-PolicyMap)#class c1
Switch(config-Policy-Class)# set ipv6 nexthop 3100::2
Switch(config--Policy-Class)#exit
Switch(config-PolicyMap)#exit
Switch(config)#interface ethernet 1/1
Switch(Config-Ethernet1/1)#service-policy input p1
Configuration result:
First, set an ACL containing one entry, names it as b1, matching source IP segment 2000::/64(permit).
Globally enable QoS function, create a class-map:c1, and match ACL b1 in the class-map. Create a
policy-map:p1, quoting c1 in p1, and set the next hop as 3100::2. Apply this policy-map on port ethernet 1/1.
After that, the messages whose source IP are within the segment 2000::/64 received on port ethernet 1/1 will
be forwarded through 3100::2.
19.4 PBR Troubleshooting Help
 At present, policy-map can only be bound to input port but not output port.
 Since hardware resources are limited, if the policy is too complicated to configure, relative information
will be noticed to users.
