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

[Andrew Jones]

Localpref is non-transitive between ASes, so I'm not sure that this 
would work if Daniel is using eBGP between his peering and edge routers.
Daniel,
Is there a reason you're running eBGP between your peering and edge 
routers, rather than iBGP?
