Hi guys,



I have a customer who peers via eBGP with Lightpath aka Cablevision (AS
6128) and Level3 (AS 3356) and wants to do some dual-WAN router redundancy.



I am not optimistic for your odds in having 6128 do anything other than /30 for you.

(Though even then you still have options, up to and including eem IP takeover)



I have heard that carriers will sometimes agree to set up a /29 WAN subnet
for a customer and peer with (2) customer routers.

Carriers who do that and more are my favorites.
