Hello, I'm trying to deploy IPv6 for our PPP customers. Our LNS is an asr-1001x, which work just fine for ipv4.
I have a strange behavior when trying to push IPv6 (NA + PD) to the client CPE (cisco 800 in my lab). *Here's my CPE dialer config :* interface Dialer1 mtu 1460 ip address negotiated ip access-group ACL_dialer1_in in ip nat outside no ip virtual-reassembly in encapsulation ppp dialer pool 1 dialer-group 1 ipv6 address autoconfig default ipv6 enable no ipv6 nd ra suppress ipv6 dhcp client pd DHCPv6 ppp authentication chap callin ppp chap hostname user@realm ppp chap password 7 xxxxxxxxxxxxxx end *Here's my LNS config relevant parts :* aaa authorization configuration DHCPv6-PD group radius ipv6 dhcp pool IPv6_DHCP_POOL prefix-delegation aaa method-list DHCPv6-PD lifetime 7200 300 address prefix 2A06:A402:1::/56 accounting default interface Virtual-Template285 mtu 1492 ip unnumbered Loopback285 no ip redirects ip access-group VC_BE_out in ip tcp adjust-mss 1420 no peer default ip address peer default ipv6 pool IPv6_DHCP_POOL ipv6 unnumbered Loopback285 ipv6 enable ipv6 nd other-config-flag no ipv6 nd ra suppress ipv6 dhcp server IPv6_DHCP_POOL no ppp lcp fast-start ppp authentication pap chap ppp ipcp dns x.x.x.x x.x.x.x ppp ipcp address required ppp ipcp address unique ppp ipv6cp address unique end So I want to give an ipv6 from 2A06:A402:1::/56 as NA address for the CPE, and PD is given by my radius with dhcp The problem I have is the following : the moment I add "ipv6 dhcp server IPv6_DHCP_POOL" in my virtual-template configuration on the LNS, the LNS sends an other access request to my radius with username = user@realm*-dhcpv6.* as this user is unknown on my radius, it gets an access-reject and the CPE's PPP session goes down. I can't find where this "-dhcpv6" suffix comes from, and I did not find doc about it. Can anyone help me please ? I'm going crazy !
