Technology Review
The following AOS BGP-related guidelines may help guide decisions made during basic BGP implementation.
Ignore route if next hop is unreachable.
Prefer route with largest weight (only used in the local router, set by applying route maps to set this value on
desired inbound updates).
Prefer route with largest local preference.
Prefer route injected by this router via network command.
Prefer route with shortest AS_PATH.
Prefer route with lowest origin type. Routes originally injected by the network command or aggregation (IGP)
have a lower origin type than those originally injected by redistribution into BGP.
Prefer routes with lowest MED value.
Before the route is installed into the route table (forwarding table), a check is made of other sources that may
have information about the same subnet (static routes, IGP, etc.) The route with the lowest administrative
distance is installed.
