BGP Communities for H.E. and Deltacom?

[graham at g-rock.net (Graham Wooden)]

Hi there,

Any one know what are the acceptable BGP communities are for H.E. and
Deltacom?
At one of our POPs we?re using an aggregate provider and I need to help them
to fix some prefixes that I am announcing from another POP (ie. Lower the
metric so only use the backhaul for failure of the other side).

I was hoping that they would be listed on the One Step?s bgp community
listing.  Any links to such documents for both HE and Deltacom would be
great and would be much appreciated. Thank you,
