PPPoE DHCPV6 (valid Global unicast IPv6 address)

[Fernando3]

Hello everyone,

I have an ASR-1004 router configured as a PPPoE server.

The IPV4 works perfectly.

But I'm having some difficulty enabling DHCPV6 in the virtual-template interface.

My clients are unable to capture a valid Global unicast IPv6 address on each connection.

My configuration from dhcpv6 to PPPoE is as follows:

ipv6 unicast-routing

ipv6 dhcp pool pool-dhcp-v6
  prefix-delegation pool pool-v6 lifetime infinite infinite
  dns-server dnsv6-1
  dns-server dnsv6-2
  domain-name mydomain.com

interface Loopback5
  ipv6 address ipv6-loop / 48

interface Virtual-Template1
ipv6 unnumbered Loopback5
  ipv6 enable
  ipv6 dhcp server pool-dhcp-v6

ipv6 local pool pool-v6 prefix :: / 48 64

Can someone help me please?

Hello,

not sure what your clients are, but typically you would need a bba-group and associate a physical interface with that group:

ipv6 unicast-routing

bba-group pppoe BBA_GROUP
virtual-template 1

!

ipv6 dhcp pool pool-dhcp-v6
prefix-delegation pool pool-v6 lifetime infinite infinite
dns-server dnsv6-1
dns-server dnsv6-2
domain-name mydomain.com

interface Loopback5
ipv6 address ipv6-loop / 48

interface Virtual-Template1
ipv6 unnumbered Loopback5
ipv6 enable
ipv6 dhcp server pool-dhcp-v6
ppp authentication pap

!

interface GigabitEthernet 0/0
pppoe enable group BBA_GROUP

ipv6 local pool pool-v6 prefix :: / 48 64

Hello Georg, thanks for the reply,

I'm sorry, I ended up not specifying which are my clients, all use common wi-fi access points, dialing PPPoE IPV4 and IPV6.

I got in touch with the support of one of the manufacturers of our access points.

They sent me the e-mail with the response described in the attached image, containing the results of data collected with traffic analysis using Wireshark between two models of routers, a D-Link (Functional) and TP-Link (Non-functional).

In the configuration I posted, I tried to show only the part of IPV6, but I had already done the part of bba-group and pppoe enable in the interface as below.

bba-group pppoe PPP
  virtual-template 1
ppp authentication chap callin

interface TenGigabitEthernet1 / 0 / 0.1010
  encapsulation dot1Q 1010
  pppoe enable group PPP
