[c-nsp] BGP Route Nailing & Reoriginating

[Lawrence Wong]

Hi Joe,

Dampening would work if we have access to R3/AS3 and/or the admin of R3/AS3 is willing to come up with customised dampening policies for the specific AS/routes that were used in the example. But this would also mean additional maintenance overheads (both on AS3 end as well as coordination between them and us) if our routes changes.

As you have mentioned, there are more policies out there than we can imagine. Our goal is simply to "keep things simple" and "manageable" within the AS2 used in the example instead of trying to get the world to change their dampening policies. I believe this should be straightforward and conservative enough. But as our experience is limited, we definitely welcome suggestions.

And FYI, this is as real and complete as it gets in our situation.


Thanks,

Your topology mentioned nothing about the global Internet.  If 
your concern is dampening, then "right tool for the right job" is 
dampening tuning. If you are asking advice with incomplete info,
expect inaccurate responses. 

In general, attempting to model the global Internet in your 
sandbox will fail.  There are more policies on the 'net then 
you can possibly ever imagine.  Be conservative and take every
step to maximize your connectivity.

If you want to lay out your real situation, I'm sure folks will 
assist.
