[c-nsp] Conditional BGP

[Paul Stewart]

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
