Category: Cumulus Linux
BGP is without doubt the most scalable routing protocol, which made it a popular choice for large-scale deployments from service provider networks to enterprise WAN/VPN networks and even data centers. Its only significant drawback is the tedious configuration process (which almost reminds me of writing COBOL programs decades ago).
A year ago Matthew Stone first heard about Cumulus Linux when I ranted about it on a Packet Pushers podcast (which only proves that any publicity is good publicity even though some people thought otherwise at that time), and when his cloud service provider company started selecting ToR switches he considered Cumulus together with Cisco and Arista… and chose Cumulus.
Carlos Mendioroz sent me an interesting question about unnumbered interfaces in Cumulus Linux and some of the claims they make in their documentation.
TL&DR: Finally someone got it! Kudos for realizing how to use an ancient trick to make data center fabrics easier to deploy (and, BTW, the claims are exaggerated).
