Folks,

As you know the basic BGP spec currently restricts a BGP speaker
to advertise at most a single route to a given destination (given
address prefix).

The purpose of this e-mail is to solicit opinions on (a) what
applications could benefit if the above restriction is relaxed, as
to allow a BGP speaker to advertise multiple routes to a given
destination, and (b) whether the IDR WG should start work on extending
BGP to support these applications.

With this in mind, please answer the following two questions:

1. What applications could benefit from allowing a BGP speaker
to advertise multiple routes to a destination ? 

2. Should the IDR WG start work on extending BGP to support
such applications ?

The deadline for response is August 29.

Yakov.
