  5. Protocol Stack - PPP over ATM

  6. ADSL configuration

  7. LNS and BAS Configuration • LNS configuration ipv6 unicast-routing aaa new-model aaa authentication ppp default group tacacs+ aaa authorization network default group tacacs+ aaa authorization configuration NITC group tacacs+ vpdn-group 1 accept-dialin protocol l2tp virtual-template 1 interface Virtual-Template1 ipv6 enable no ipv6 nd suppress-ra ipv6 dhcp server ADSL-Pool ppp authentication chap callin ipv6 dhcp pool ADSL-Pool prefix-delegation aaa method-list NITC • BAS Unaware of this configuration

  8. Recommended address allocation

  9. Ipv6 Address Allocation Guideline • RFC 3177 recommends the following : A single PC, with no additional need to subnet, dialing-up from a hotel room may receive its /128 IPv6 address for a PPP style connection as part of a /64 prefix. • Give Home/SOHO a permanent /64 – single link • Short-lived /64 from a prefix-pool A Separate /64 is assigned each user/interface. The prefix is advertised in RA’s and a route is installed in the RIB.

  10. Give home users a permanent /64 – single link

  11. short-lived /128

  12. THANK You
