Hi,

I think BGP maximum-path it's solution what are looking for which by default is 1. Change to 2 then it should be ok. ISPs should be advertising default routes.

Configuration:

router bgp ZZZ

neighbor x.x.x.x remote-as 4700

neighbor y.y.y.y remote-as 4700

maximum-paths 2

Verify:

sh ip route

The link

Hope it will help.

Hi,

this will install multiple BGP routes for the same prefix in the RIB but the load-sharing will still be taken in charge by the switching process which is CEF by default and the traffic will be load shared by src-dst IP.

ip load-sharing per-packet

Hi,

yes of course but It is highly recommend not to use per-packet load sharing.
