RE: BGP Load-balancing.

First Configure - "maximum-paths [ibgp]"

Then if the following conditions are met (loadbalancing conditions for BGP)-

- 1) The same set of path attributes up to the MED, i.e. weight,
Local Preference, Origin, MED
- 2) Are of the same type, i.e. both learned via iBGP or eBGP
- 3) Have the same IGP cost to reach their NEXT_HOP IP address.
- If the above conditions are met and maximum-paths [ibgp] is
configured under the BGP process, then BGP will install multiple equal-cost
routes into the local RIB and use them for load-balancing.
