 图中的R1作为LAC，R2作为LNS，Net桥接到物理网卡

 LAC:

hostname lac
aaa new-model
aaa authentication ppp default none

vpdn enable
vpdn search-order domain

vpdn-group 1
request-dialin
protocol l2tp
domain fc.ln
initiate-to ip 1.1.2.2
local name LAC
no l2tp tunnel authentication

bba-group pppoe global
virtual-template 1

interface Ethernet0/0
ip address 1.1.2.1 255.255.255.0

interface Ethernet0/1
ip address dhcp
pppoe enable group global

interface Virtual-Template1
mtu 1492
ip unnumbered Ethernet0/1
no peer default ip address
ppp authentication pap chap

LNS:

hostname lns
aaa new-model
aaa authentication ppp vpdn local

vpdn enable
!
vpdn-group 1
accept-dialin
protocol l2tp
virtual-template 1
terminate-from hostname LAC
lcp renegotiation always
no l2tp tunnel authentication
!
!
username lnsuser@fc.ln password 0 lnsuser
!
interface Ethernet0/0
ip address 1.1.2.2 255.255.255.0
!
interface Virtual-Template1
ip unnumbered Ethernet0/0
peer default ip address pool mypool
ppp authentication pap chap vpdn
!
ip local pool mypool 192.168.0.10 192.168.0.20
图中的network是桥接到我自己的VMware网卡了

桥接完成后，从物理机ping一下模拟器里面的R1

可以看出从VMware 网卡VMnet1的DHCP服务器中获取到的IP地址为192.168.229.136，用物理机ping 192.168.229.136如果可以ping通，则认为网络连通性正常，可以继续进行拨号配置；
