Hello Shivlu,

in one of our routers the backup link is configured in this way

pseudowire-class netvision-l2tp

encapsulation l2tpv2

!

interface Virtual-PPP1

description NETVISION DIALER

ip address negotiated

ip nat outside

ip virtual-reassembly

no cdp enable

ppp pap sent-username password 0 41003827

pseudowire x.x.x.x 2 pw-class netvision-l2tp

crypto map VPN_MAP

!

where x.x.x.x is a public ip address

ip route x.x.x.x 255.255.255.255 g0/1

completes this solution where this g0/1

sh run int gi0/1

Building configuration...

Current configuration : 157 bytes

!

interface GigabitEthernet0/1

description CONNECTION TO CABLE MODEM

ip address dhcp

ip virtual-reassembly

duplex auto

speed auto

media-type rj45

end

and it receives a private ip address from DHCP on a cable modem access network.

but it uses l2tpv2 not L2tpv3 and I've always seen l2tpv2 in this context.

Hope to help

Giuseppe
