Configuring IPv4 and IPv6 Interface Columns over Static and Dynamic PPPoE

You can configure IPv4 and IPv6 interface columns over static and dynamic PPPoE, as shown in Figure 1.

Figure 1: IPv4 and IPv6 Interface Columns over Static and Dynamic PPPoE

To configure IPv4 and IPv6 interface columns over dynamic PPPoE:

1. Specify the loopback mode for an interface and assign both IPv6 and IPv4 addresses to the interface.
   host1(config)#interface loopback 1host1(config-if)#ipv6 address 2000::1/64host1(config-if)#ip address 2.2.2.1/24
2. Create a profile that defines attributes for the dynamic interface. You can use this profile to configure IPv4 or IPv6, or both IPv4 and IPv6 PPP interfaces.
   host1(config)#profile ipv4Ipv6Profilehost1(config-profile)#ip virtual-router ppphost1(config-profile)#ip unnumbered loopback 1host1(config-profile)#ipv6 virtual-router ppphost1(config-profile)#ipv6 unnumbered loopback 1host1(config-profile)#ipv6 nd other-config-flaghost1(config-profile)#ipv6 nd ra-interval 10host1(config-profile)#ppp authentication chaphost1(config-profile)#exit
3. Specify the interface.
   host1(config-if)#interface gigabitEthernet 4/0/6
4. Set the encapsulation type to PPPoE.
   host1(config-subif)#pppoe
5. Configure the interface to detect and accept dynamic PPPoE subinterfaces.
   host1(config-subif)#pppoe auto-configure
6. Assign the profile to any autoconfigured encapsulation.
   host1(config-if)#pppoe profile any ipv4Ipv6Profile
