These newly created etX ports are accessible and configurable from cEOS Cli and on start are in switching mode (meaning they don’t have an IP address assigned).

An important thing for this example is, that cEOS creates a port for every ethX port (except eth0), which is bridged with it. cEOS with “common” CLI, distribution and a Docker container, provides an easy to use solution for this demo. cEOS NodesĬEOS ( containerized EOS) is an operating system for network devices from Arista (similar to IOS from Cisco). We will use Docker auto-generated networks in this example. 1 host address), these masks are not applicable in this case. However, since Docker also connects the host to the network (with. Typically, networks with 2 nodes connected use /31 or /30 masks. We have 4 docker containers connected with two docker networks. Let’s take an example of the following topology:įirstly, let’s break down what we see in the picture. A full-mesh topology is changed to a star topology. This peer will, in turn, forward it to all other peers. This approach allows one IBGP to act as a route-reflector and all IBGP peers will send routing information only to that peer. The design of a method known as “ route reflection“ was introduced, to alleviate the need for “full mesh” peering. This operation often represents a serious scaling problem. This way, external routing information can be re-distributed to all other routers within that autonomous system. To prevent loops, all BGP speakers within a single autonomous system must be fully meshed.

“don’t forward routing information received from one IBGP peer to another IBGP peer” Since the Internal BGP (IBGP) peers must follow the rule: The Border Gateway Protocol (BGP) is a routing protocol, designed for TCP/IP internets. We are using OpenDaylight-BGP plugin for this demonstration. The main goal of this project is to create a Docker container, that can be connected to an existing network and provide route-reflector functionality.
