We have a Hub and Spoke MPLS network with SAP and Email application hosted in IDC.
At remote site we have dual links from different service provider.
Aim is to access the SAP traffic from one link with backup on the other link in case of primary link failure.
Also Email should run from other service provider with backup on the first service provider in case second service provider fails.
How can we achieve this using BGP between CE-PE.
Secondly at few locations we have only few network users approx -10 Nos and we want some users to go out from service provider 1 and the rest on the other service provider with backup on service provider available on given point of time in case either service provider link fails at the remote site.
