ACI Application Centric Deployment (ACD) and Subnet Sharing with Route Leaking

Leave a Comment /

1. Overview In Cisco ACI, a powerful feature called route leaking enables applications and services to communicate seamlessly across Virtual Routing and Forwarding (VRF) instances. This allows for efficient data flow within the network infrastructure, even when applications reside in separate VRFs for security or isolation purposes. Route leaking achieves this by sharing routing information […]

Overview Route leaking in Cisco VXLAN EVPN fabrics plays a critical role in enabling communication between workloads residing in different L3 VXLAN Network Segments (VNIs), VRFs. It essentially allows these workloads to seamlessly access resources and services provided by shared services or external networks. VRF (Virtual Routing and Forwarding) – VRFs are leveraged to establish

Cisco ACI Floating L3Out

Leave a Comment /

ACI uses L3Out to connect to external L3 domains via routing (dynamic routing protocol or static). There are multiple options and tools to optimize the L3Out for effective L3 communications between ACI and external network services. One of those is Floating L3Out.

Floating L3Out enables engineers to configure L3Out without specifying logical interfaces. Floating L3Out makes configuration, management, and troubleshooting easier. Only specific leaf nodes, called anchor leaf nodes establish routing adjacencies with external routers.

Anchor leaf node – is a leaf node that establish route peering / L3 adjacencies with the external routers. As of Cisco ACI release 6.0(1), the verified scalability number of anchor leaf nodes is 6 per L3Out.
