BGP Maximum load-balance

the problem

========

When using the command maximum load-balance , the routes recieved from EBGP peer will be advertised to IBGP Peers with next-hop changed to local.


The solution

==========

if one router recieve two equal cost routes from ebgp peers ,he will send this routes to his IBGP peers and change the next-hop to himself 
but if he recieve one route from EBGP ,he will send the routes to the IBGP without changing the next-hop

I usually configure next-hop-local, no matter how many routes it will receive from the EBGP peers.
