What is a BGP router server?

A BGP route server is basically an eBGP route reflector (not a BGP terminology) and performs the same route reflection function as an iBGP route reflector. BGP route server provides an alternative option to full eBGP mesh peering between ASes. Like iBGP RR, it doesn’t need to be in the data path to perform the route reflection. In data centers, the BGP route server is commonly used in VXLAN EVPN multi-site deployments; However, in service provider networks, it is used to connect several internet exchange (IX) operators.

BGP Route Server Explained: Use Cases and Practical LAB Demo

A BGP Route Server is a feature designed specifically for internet exchange (IX) operators. It provides an alternative to full mesh external BGP peering among the service providers with a presence at the IX. The route server provides eBGP route reflection with customized policy support for each service provider.

In this comprehensive video guide, I explained the BGP route server, paying particular attention to its implementation on Cisco switches and routers.
