>I do understand the reasoning behind preferring customer routes. However in the case where a customer of a customer also connects to you directly via peering doesn't it make sense to prefer the direct connection? or at >least not prefer the customer learned routes.
Business not technical. Fill up the bandwidth and they will buy more!!
>In our situation, we were buying transit, heavily prepended, from a provider on a tiny circuit. The purpose of the transit was related to another service we were acquiring from that provider and wasn't about the transit, but >the transit was needed for the service to work reliably. Unfortunately this provider was also a HE customer and so we now had all of the HE traffic coming down this tiny link, since all of our other transit providers and >ourselves only peered with HE.
>I don't remember why, but we couldn't have the transit provider not announce our routes toward HE, so we ended up doing the announce more specifics everywhere else thing. Which I hate doing on so many levels.
>Thus the desire for a community to tell HE that although they learned this route from a customer, it is not a customer route.
You can use communities to set the local preference with HE.
This should do the trick
6730:0008 set local pref to 64 (lowest they have afaik)
Provided that your provider accepts it and propagates it.
Or you can ask them to set it for you.
