New version. Less duplication and a nice feature as bonus. With softreconfig in enabled the looped prefixes are accepted into the Adj-RIB-In. This means that I can tell if my neighbor AS is using a path via myself. Either I'm tired or that is cool. router-02# bgpctl show rib 192.168.0.0 flag

bgpd does not re-route correctly when I shut down a transit when I use a bgp-only design, causing black-holes for some prefixes. router-01 and router-02 are in the same AS and peer with the same transit provider. router-01 and router-02 have two ibgp peerings, primary and standby path. router-01 s
