Less than 10% of IPv4 Addresses Remain Unallocated

Saw this from ARIN today…

We really need IPv6 PPP support in Mikrotik!!!

Yes we do!

RFC2472
http://www.faqs.org/rfcs/rfc2472.html

Linux PPPv6

I heard the intent with IPv6 is to assign each user at least one subnet and likely more. So each device in there home will have a public v6 IP. Does the PPPoE protocol support handshaking and telling the client what size subnet it is being given?

PPP doesnt need to support it. PPP is just a point to point connection and you create a route on the CPE and the border router.

PPPoE ‘needs’ to support it…

6

Why? It functions the same way as any other encapsulated ppp connection.

PPPOE connection 10.0.0.1 on server to 10.0.0.2 on client. Client has IP range 1.2.3.0/28. Server has a route (can be supplied by radius) to route 1.2.3.0/28 via 10.0.0.2. CPE default gateway is 10.0.0.1. CPE lan IP address is 1.2.3.1/28, hosts behind client cpe are 1.2.3.2/28 thru 1.2.3.14/28 with default gateway 1.2.3.1.

Works like a champ.

Know anyone that needs a “super B” range…

So have you made this work? On over a hundred PPPoE clients as well?

I see this in old change log.

“What’s new in 3.18:
…
*) do not send IPv6 packets over PPTP, L2TP or PPPoE - could confuse some
servers or clients;”

The thread got off track. Ive never tried it on IPv6, but I do it on IPv4 w/ OpenVPN and L2TP.

Yes, IPv6 needs to be supported. But I dont think the PPP protocol needs to be rewritten to send subnet information across the link. There are other standard ways to handle that.
