BGP additional path limit increased to 255 6.4.3

Up to 255 BGP paths can be selected and advertised. Previously, the limit was eight paths.

In this example topology, each spoke has multiple VPN tunnels that connect to the hub with ADVPN and runs spoke-hub to establish multiple BGP neighbors on all of the tunnels.

To set the additional path limit to 255:
config router bgp
    set additional-path-select 255
    config {neighbor | neighbor-group}
        edit <ip address>
            set adv-additional-path 255
        next
    end
end
