As per wikipedia – Fusion<\/strong><\/em> is the process of combining two or more things together into one.<\/p>\n\n\n\n

So it is the same here – when you deploying SD-Access in the Brown or Green Field deployment – you need to integrate exiting Live Traditional network with the new SD-Access Fabric network. ( Since most of the shared Services always resides outside Fabric).<\/p>\n\n\n\n

Cisco SD-Access Border connecting External Domain with existing Global Routing Table should use a \u201cFusion\u201d router with MP-BGP & VRF import\/export.<\/p>\n\n\n\n

The function of aggregating VRFs (VNs) and\/or leaking routes between them can be done on any device that supports the features required (VRF, BGP, etc.) – this mostly connected to exiting CORE Routers.<\/p>\n\n\n\n

Example like below Fabric with Shared Services (where Shared Services will be located in Existing DC Environment).<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Network Layer connection to exiting DC or CORE network.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Routing
\u2022 What traffic will be routing through this device?
\u2022 What protocol is used in the Global Routing Table?
\u2022 What type of leaking does the protocol support (route-map, etc.)?
\u2022 What Subnets\/Routes need to be shared?<\/p>\n\n\n\n

Finally, The Role of  Fusion Router in the fabric VRF\u2019s subnets that need access to these shared services will be leaked into GRT(Global Routing Table), and vice-versa. Route maps can be used to help contain routing tables to subnets specific to SDA Fabric.<\/p>\n\n\n\n

What device can be use here for Fusion Router – Personally any device which support below features ( can be router \/ switch \/ Firewall)<\/p>\n\n\n\n

– IP routing<\/p>\n\n\n\n

– Support for dynamic routing protocols (ISIS, BGP, EIGRP, etc.)<\/p>\n\n\n\n

– VRF support<\/p>\n\n\n\n

– Route redistribution<\/p>\n\n\n\n
