Abstract
This document establishes terminology to standardize the description
of benchmarking methodology for measuring eBGP convergence in the
control plane of a single BGP device. Future documents will address
iBGP convergence, the initiation of forwarding based on converged
control plane information and multiple interacting BGP devices. This
terminology is applicable to both IPv4 and IPv6. Illustrative
examples of each version are included where relevant.
