Distributor for L3 Active-Active, N+1 Amphora Setup

Registered by Jason Niesz on 2017-03-29

This blueprint describes a L3 active-active distributor implementation to support the Octavia active-active-topology. The L3 active-active distributor will leverage the capabilities of a layer 3 clos network fabric in order to distribute traffic to an amphora cluster of 2 or more amphoras. Specifically, the L3 active-active distributor design will leverage Equal Cost Multipath Load Sharing (ECMP) with anycast routing to achieve traffic distribution across the amphora cluster. In this reference implementation, the BGP routing protocol will be used to inject anycast routes into the L3 fabric.
