9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
In Non-Deterministic mode, paths are compared in the order in which they arrive. This method can lead to the
system choosing dierent best paths from a set of paths, depending on the order in which they are received from
the neighbors because MED may or may not get compared between adjacent paths. In Deterministic mode (no
bgp non-deterministic-med), the system compares MED between adjacent paths within an AS group
because all paths in the AS group are from the same AS.
When you change the path selection from Deterministic to Non-Deterministic mode, the path selection for existing
paths remains Deterministic until you enter the capture bgp-pdu max-buffer-size command to clear
existing paths.
bgp recursive-bgp-next-hop
Enable next-hop resolution through other routes learned by BGP.
