[c-nsp] IP SLA?

[Dan Brisson]

I'm curious what folks do in the situation where you have redundant 
links to your customers.  I'm speaking primarily in co-lo environments 
where you offer redundant Internet connectivity to co-lo customers.  So 
for example, you give a customer 2 ethernet handoffs from two separate 
Layer 2 switches.   Now what do you do if the customer wants to go to a 
routed model using both links.  I could allocate /30s for both links, 
but then I have the issue of how to reliably route their block to them 
w/out running a routing protocol that will detect if one of the links 
goes down.  That's where I came to static routes with IP SLA but I 
wanted to make sure I wasn't missing something easier.

Thanks!
