what is the best practics is it ( OSPF or BGB ) and who is the aplicable more for the faiuler senario from the DC side & from the Brach side ?

Hi

You have connection to two different service providers and for ease of management and effective link utilization I would suggest to use BGP.

BGP is a more granular protocol than OSPF and unlike ospf  it had multiple attributes to unfluence path selection.

Moreover, these days many providers have started uaing BGP with customers as that implementation is easy.

This is applicable for both dc and remote sites. Let me know if you have more queries.

Hello Othman,

I completly agree with what Vivek has said. Using BGP as a PE-CE protocol makes the life easy for the service provider, I didn't mean that other protocols makes life tough but BGP is really cool. You have so many attributes to tune in to. You can avoid process oriented configurations like redistribution and all those stuff.

Ospf has some platform limitations in terms of the amount of processes it can handle (per vrf instance) which can be limiting. Things like sham links also add a config burden where the SP would want as simple a deployment as possible.
