Hi,
I have a requirement for a PPP Client who is only utilising IPv6 to be able to ping an IPv4 only end point.... Let me show you the flow of traffic:
The actual L2TP tunnel is initiated between two IPv4 Peers and should have no influence on the contents of the tunnel.
PPP Client (S0/0 - IPv6) --> S0/0 (PPP)LAC --> ge-1/3/1(PPP) LNS --> (ISIS IGP) MX240 Core --> Transit (IPv4 or 6)
The test can be to ping from the PPP Client to the far end (Transit IPv4) and see if we get a response. In the real world the PPP Client will be our customer who wants to traverse our ISP network and maybe contact a pure IPv4 interface on the internet, or a server somewhere.... this is what we need to replicate and have working....
What is the best way to achieve this and how?
Nat64 at the client ---- Fa0/0 IPv4/IPv6 (Customer facing CPE interface) - S0/0 IPv6 (LAC facing interface) on the client PPP...
DSLITE?
Tunneling?
Thanks
