5. BGP Route Selection Process
Before anything -- if a route is not synchronized, it is thrown out!!
The address/network given for the next hop is available in the IP routing table
The route with the highest Weight attribute (the Weight attribute is Cisco proprietary)
The route with the highest Local_Preference attribute
Any routes that were learned Locally self-originated (next-hop = )
The route with the shortest AS_Path attribute (confed learned paths are not included.)
The route with the lowest Origin [internal (0), external (1), incomplete (2)]
The route with the lowest Multi-Exit Discriminator (MED)
The route learned via EBGP (iBGP routes are discarded at this point)
The route with the nearest IGP neighbor
The oldest learned route
The route with the lowest BGP router-id
