Hi all I am trying l2tp.
r1-------r2(LNS) -------------r3 (LAC)-----------r4 r2 is the LAC and r3 is the LNS. I don't have a PC and hence I am using r1 as the PPP client. R1 will send PPP packets to R2 (LNS) using PPPoE. With l2tp, when the r2 (LNS) gets the PPP packet from R1, using the domain name or dnis it searches of whether it is a VPDN user. If yes, it initiates l2tp tunnel to LNS. Only with ISDN or Analog modem, we can use DNIS. Here the only possible way is to use domain name. I have configured r1's g0/1 interface with pppoe that is connected to r2 (lns). There are two issues for me. 1) How do I make r1 to send the domain name in PPP session? Should I use usern...@domain-name when authenticating with chap? 2) How do I terminate the PPPoE session at r2 (LNS)? Should I use the same vpdn group that I used for l2tp or a different one. If I try to configure different vpdn group, I see only l2tp. pppoe, pptp and any are not there Can someone please fix the missing configuration. *R1 config* interface g0/1 no shutdown pppoe-client dial-pool-number 1 pppoe enable interface Dialer0 exit default interface Dialer0 interface Dialer0 ip mtu 1452 no shutdown ip address 10.20.30.41 255.255.255.0 dialer pool 1 dialer-group 1 encapsulation ppp dialer idle-timeout 120 dialer fast-idle 20 exit dialer-list 1 protocol ip permit *LAC configuration* hostname LAC username LAC password 7 0107130A550E0A1F205F5D username LNS password 7 001006080A5E07160E325F username dialupuser password 7 14131B0A00142B3837 vpdn enable vpdn search-order domain vpdn-group 1 request-dialin protocol l2tp domain cisco.com initiate-to ip 20.1.1.2 local name LAC *LNS config* hostname LNS username LAC password 7 0107130A550E0A1F205F5D username LNS password 7 120D10191C0E00142B3837 username [email protected] password 7 104A0018090713181F vpdn enable vpdn-group 1 accept-dialin protocol l2tp virtual-template 1 terminate-from hostname LAC local name LNS interface Virtual-Template1 ip unnumbered Ethernet0 no ip directed-broadcast no ip route-cache peer default ip address pool mypool ppp authentication chap http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a0080093f6f.shtml With regards Kings
