I need a better information on BGP vs. OSPF
We have a enterprise network, all locations connected through MPLS and DMVPN for internet and BGP was running on both links. Recently one third party guy Mr. Thomas advised my management (who helped at starting this network build) to convert from BGP to OSPF, still I opposed to his advise as....
1. OSPF will consume more bandwidth than BGP
2. Need to create so many areas and the same time update between those areas will become delay
3. OSPF required periodic update where BGP do not required
Here could you give better things about BGP than OSPF and I need your high priority help to prove it at my management.
Thanks in Advance
