Current network overview Let’s start by taking a high-level look at our DC network routing topology. The core routing protocol is OSPF, it is responsible for distributing routing information between the Core and WAN layers of the network. WAN layer consists of two MPLS L3VPN services running BGP as PE-CE protocol and two DMVPN Hubs running EIGRP. All WAN layer devices perform mutual redistribution between the respective WAN protocol and OSPF.
