How to multihome endusers [was: Cogent/Level 3 depeering]

Sun Oct 9 10:52:37 UTC 2005

Yes, indeed, I think it makes sense to multihome my humble enduser pc.

Right now all I can get is aDSL and it does not matter what provider
because they all use DTAG.DE infrastructure.

Maybe cable will be choce. It is not as fast as aDSL at least not here
and it will take another two or three years until they deploy it. If
it does not get shot on site again by the regulation office or the
cartell office again.

So I will end up having a cable-modem speaking ethernet/PPPoE and an
aDSL-modem speaking ethernet/ tcp/ip and DHCP.

My ip adresses probably will be 84.167.xxx.xxx for aDSL and
24.xxx.xxx.xxx for the cable.

I can talk to no-ip.com, they will allow a second ip for

host_look("84.167.252.166","echnaton.serveftp.com","1420295334").
host_name("84.167.252.166","p54A7FCA6.dip.t-dialin.net").

Its entry will look a bit like this one:

host_look("81.88.34.51","Kunden2.KONTENT.de","1364730419").
host_name("81.88.34.51","kunden2-1.kontent.de").
host_look("81.88.34.52","Kunden2.KONTENT.de","1364730420").
host_name("81.88.34.52","kunden2-2.kontent.de").

So I will end up with 3 names and 2 ip addresses for my humble
host.

Do I need BGP now or OSPF or can I rely on RIP.
Do I need an AS number?
How do I get it?

Imagine not a fool like me is asking this but some 32K end
users of DTAG.DE connected to a DSLAM at Franfurt/Main in
germany.

I guess the number of end users disconnected be Cogent and
Level 3 is not much smaller.

Asbestos parapluis opened.
Shoot now!
