Min wait advertise timer

The operational value of min-wait-to-advertise (0 if the feature is disabled)

Established peers at min wait timer expiry

The number of address-family peers that were established when the min-wait-to-advertise command timer value expired (N/A if the feature is disabled)

Current established peers

The current number of address family peers that are in the established state

First session established time

The time, relative to BGP instance restart at time T=0, when the first address family session was established.

This stops being tracked when the min-wait-to-advertise timer expires.

Last session established time

The time, relative to BGP instance restart at time T=0, when the last address-family session was established.

Max Wait advertise timer

The operational value of the max-wait-to-advertise command for the address family (0 if the feature is disabled)

Converged peers

The number of address-family converged peers. This is the number of BGP neighbors that have, up to now, sent an EOR marker for the address family. N/A if the feature is disabled.

Converged state

The convergence state of the address family: waiting, started, partial, timeout or converged. N/A if the feature is disabled. Waiting is when no peers have reconnected yet.

The waiting to start transition occurs when the first session comes up.

The started to partial transition occurs when at least one address-family peer has sent the EOR marker.

The partial to converged transition occurs when all address-family peers that have been up continuously since the min-wait-to-advertise timer expired have sent the EOR marker.

The partial to timeout transition occurs when the max-wait-to-advertise timer expires and not all address family peers that have been up continuously since the min-wait-to-advertise timer expired have sent the EOR marker.

Converged time

The convergence time of the address family after the last restart, relative to BGP instance restart at time T=0. N/A is displayed if the convergence state is waiting, started, partial or timeout.
