Ignore routes with an inaccessible next hop address!
- Prefer the path with the highest WEIGHT (Cisco proprietary and only of local significance).
- Prefer the path the with highest LOCAL_PREF.
- Prefer the path that was locally originated via a network command.
- Prefer the path with the shortest AS_PATH. **
- Prefer the path with the lowest origin type.
- Prefer the path with the lowest multi-exit discriminator (MED)
- Prefer eBGP over iBGP paths.
- Prefer the path with the lowest IGP metric to the BGP hop.
- Determine if multiple paths require installation in the routing table for BGP Multipath.
- When both paths are external, prefer the path that was received first (the oldest one).
- Prefer the route that omces from the BGP router with the lowest router ID.
- If the originator or router ID is the same for multiple paths, prefer the path with the minimum cluster list length.
- Prefer the path that comes from the lowest neighbor address.
** This attribute is the normal tie-breaker if all settings are left at default.
