[AusNOG] Preferencing Peering BGP over Transit BGP session on Mikrotik

[Damien Gardner Jnr]

Just modify the input filter for the peering session on your peering router
to increase the localpref of the received prefixes (BGP Actions - >Set BGP
Local Pref - set it to something higher than what you're setting for
transit, but lower than what you are setting for prefixes received from
your customers). As long as you're not modifying the localpref of prefixes
received from the peering router on your edge router, then it'll accept
that, and you'll see traffic go to peering rather than transit.

 We ran to the sounds of thunder.
We danced among the lightning bolts,
 and tore the world asunder
