Michael,

I do have my own portable address space, I cannot apply for an ASN until I
am ready to proceed - I guess this is to stop people applying who then do
not go ahead with the BGP routing.

Does anyone know if a Cisco 2503 will allow me to do BGP, 1 frame link and
one BRI.  From the docs I've seen it will but it would be nice to have it
confirmed.

Cheers
craig

Hi there,st

Hi,

A few questions:

Do you have your own IP addresss space (PI) ? Do you have your own ASN ? In
general I'd say the way to
go would be to speak BGP with your upstreams, but you might also do fairly
well with static routes seconded
by floaters (depending on how your space is announced by your upstreams ?)

I run a small ISP and now require the ability to multihome.  I have read an
article that says (using a cisco router) I can add two default routes, with
different priorities.  I am not sure how this will help me though, because
if the primary link goes down, the data can not travel back because the
primary link is down - we had this problem before when we were blackholed by
a previous ISP's BGP routing tables).
So my question is how can I cheaply achieve a redundant link?
Cheers
