L2TP - Lab Example

Hi Fellas,

Here we got yellow ISP, most important thing, customers want you to bridge their Layer 2 network.
You have just IP network, not MPLS ( Fuck we are not able to use VPLS ! ), that's the  time for L2TP.

I will configure manuel L2 Tunnels instead of dynamic and I am not going to use l2tp class authentication.

For  PE 1 :

pseudowire-class test
 encapsulation l2tpv3
 protocol none
 ip local interface Loopback0


interface FastEthernet0/0
 no ip address
 speed 100
 full-duplex
 no cdp enable
!
interface FastEthernet0/0.5
 encapsulation dot1Q 5
 no cdp enable
 xconnect 100.0.0.33 15 encapsulation l2tpv3 manual pw-class test
  l2tp id 1 2

For PE2 :

pseudowire-class test
 encapsulation l2tpv3
 protocol none
 ip local interface Loopback0

interface FastEthernet0/1
 no ip address
 speed 100
 full-duplex
 no cdp enable
!        
interface FastEthernet0/1.5
 encapsulation dot1Q 5
 no cdp enable
 xconnect 100.0.0.11 15 encapsulation l2tpv3 manual pw-class test
  l2tp id 2 1

l2tp id : x y

x: local
y: remote

Also we can use the authentication for both sites;

l2tp-class sifre
 hostname deniz
 password 7 040A59555B

Just be sure that

under the pseudowire-class test section; define as
 protocol l2tpv3 sifre

so you are good  to go, Cust 1 and Cust 2 can ping each other for Vlan 5 .



  My next lab will be,

PPP Session transport with L2TP .

Cya !
