Abstract:
Data centers have become critical components of the infrastructure
used by network operators to provide services to their customers.
Data centers are attached to the Internet or a backbone network by
gateway routers and one data center typically has more than one
gateway for commercial, load balancing, and resiliency reasons.
Segment routing is a popular protocol mechanism for operating within
a data center, but also for steering traffic that flows between two
data center sites. In order that one data center site may load
balance the traffic it sends to another data center site it needs to
know the complete set of gateway routers at the remote data center,
the points of connection from those gateways to the backbone network,
and the connectivity across the backbone network.
This document defines a mechanism using the BGP Tunnel Encapsulation
attribute to allow each gateway router to advertise the routes to the
prefixes in the data center site to which it provides access, and
also to advertise on behalf of each other gateway to the same data
center site.
