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

LNS:

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；
