[c-nsp] Conditional BGP

[Paul Stewart]

Thanks to everyone for all the replies both offlist and onlist... quite a
few of them! ;)

Anyways, we're going to offer all three options to these customers - I want
to put the control in their court which as Stephen and others have
suggested.  Then the responsibility is on the customer which "route" they
prefer (sorry, bad pun).

Currently these customers are both getting full tables and could handle an
additional table with no issues at all.  

Appreciate the feedback from everyone..

Paul

Wouldn't having them prepend their AS enough times for prefixes towards
you and a low local preference for routes from you (on their end) solve
this?  That way all the configuration is on their end.

Hi folks..

 

We have a couple of customers that are looking to purchase an Internet
connection from us - this will be a BGP feed to each customer as they
are
multihomed today etc.

 

Normally, we would just supply a full table and let them decide what to
do
with it.  In this scenario, they both wish to use us as a backup
provider
and wish to ONLY use our network if their primary provider (Cogent) is
down.

 

What is common practice for this scenario?  We would still prefer to
just
send a full table and put the control into their hands but I'm also
concerned if they will have the technical expertise to accomplish this..
On
their side, what would be common practice?  I've been looking at
conditional
BGP advertisements using route-maps but don't believe that's the best
solution..

 

Thanks for your input.

 

Paul
