"UPA must be sent for the prefix that is used to resolve BGP prefixes." Are you saying that UPA is only /32 or /128 ? So if my PE has /64 loopback and I use it for next hops I can not send UPA for /64 ? And how would ABR know what I am using as BGP next hops if it may not even run service BGP at all ? Thx. R.
