MP-BGP Definitions MP-BGP is the protocol leveraged by ACI fabric nodes to propagate learned external routes into the fabric. MP-BGP and iBGP use the same Autonomous System Number (ASN) runs on all fabric nodes (leafs and spines) to propagate routing information received from external routes within the fabric. It is optional to configure one spine as a MP-BGP Route Reflector, which simplifies BGP route propagation. Ideally configure more than one spine for this role for redundancy purposes. The fabric nodes receiving routes from the Route Reflector are called Route Reflector clients. carries endpoint reachability information between pods. If a BGP Route Reflector is configured, then: the border leaf peers with each Route Reflector using iBGP else: the border leaf peers with all BGP speakers in the Autonomous System using iBGP. The ASN is configured under the Route Reflector configuration page. MP-BGP Configuration Create a BGP Route Reflector Policy Go to System –> System Set...

System health and faults ACI gathers and correlates information into Health Scores and Statistics, both help guide our troubleshooting process. We can see the health score of ACI components in various granularity levels. For example, there is a health score for an Application Profile, and a health score for each EPG within it. The sum total of the faults in the ACI fabric can be seen under System –> Faults : Viewing the ACI topology Go to Fabric -> Inventory -> Topology The topology feature displays only the active components, i.e. failed devices or devices put in maintenance are not displayed here, but rather under Unreachable Nodes or Unmanaged Fabric Nodes . Therefore this menu is not enough to have a complete view during any troubleshooting gig. ACI presents a couple of options when we right-click on a node in the topology. We can for example click on Navigate To button to go to the page details of a desired node. For example, right-clicking on Leaf1-101 then clickin...
