My company is using the Verizon Business MPLS infrastructure to connect our sites together. Currently, each site has it's own Firewall and internet connection and things are working fine. However, at a couple of sites, we want to remove the FW and Internet connection and route all traffic across the MPLS network to our data center and out to the internet from there. The remaining sites will continue to use their existing internet connections.
I am currently using OSPF as my IGP and successfully redistributing (via route maps) network to/from BGP. Also, I currently have a static default route that points to the firewall. This needs to go away and send everything over the MPLS network.
I guess the question is, what is the best way to advertise a default route to selected sites so that they get routed across the MPLS network?
Here is a sample config from my data center router...
router ospf 6500
redistribute bgp 6500 subnets route-map Allow_from_BGP
network <data center internal network> area 0
router bgp 6500
redistribute ospf 6500 route-map Allow_into_BGP
neighbor <Verizon Router> remote-as 65000
