Abstract Abstract
When BGP route servers are used, the data plane is not congruent with When BGP route servers are used, the data plane is not congruent with
the control plane. Therefore, peers at an Internet exchange can lose the control plane. Therefore, peers at an Internet exchange can lose
data connectivity without the control plane being aware of it, and data connectivity without the control plane being aware of it, and
packets are lost. This document proposes the use of a newly defined packets are lost. This document proposes the use of a newly defined
