MPLS with BGP as a routing protocal
Dear Experts:
It was observed ISP have not used BGP as a routing protocal for the MPLS VPN, we have around 15 spoke locations as of now at the HUB location static routing is done , for this i opposed and have asked the fortigate 300 firewall/router administrator to configure the Dynamic routing for this he said if to configure dynamic routing ISP should configure all the cisco routers routing for BGP then fortigate300 can also be configured for the dynamic using BGP do not know how far this is correct.
can anybody help me in suggesting is it highly recommended to configure the BGP as a routing for the MPLS VPN (HUB and spoke technology) so that will ask ISP to configure BGP as a routing protocol.
We would like to share the internet to the spoke locations few users from the HUB location and applications to be used from the spoke loactions are CRM/ERP ,FTP, smb and etc.

Depending on the size of your deployment (or growth thereof), setting up one or two route reflectors might even be the best choice ... that way, instead of altering multiple router configs to add new routers to the network, all you need is set up the route reflector peering from the new routers, and all others in the one or multiple VRFs will know of the new site. Also, the peering sessions for the route reflector clients are all more or less identical, something like this:
Depending on the structure, you will also need some IGP like OSPF to transport the routes for the point to point links etc.
neighbor RR peer-group
neighbor RR remote-as 12345
neighbor RR update-source Loopback0
neighbor RR version 4
neighbor 1.2.3.4 peer-group RR
neighbor 1.2.3.5 peer-group RR
(plus additional settings in either address family IPv4, IPv6 or vrf)Depending on the structure, you will also need some IGP like OSPF to transport the routes for the point to point links etc.
