One of the common taglines parroted by SDN aficionados goes along the lines of “The cost to acquire and manage server and storage architectures has declined over time while networking stays stubbornly expensive.” (I took it straight from an anonymous blog comment).

Let’s see how well it matches reality.

Test-driving EVPN route publishing with GoBGP

In recent times there has been a lot of interest in tunnel based L2 networks, especially for Cloud Networks implemented with VXLAN.  The tunnel based networks were initially proposed with the idea of alleviating the 4k limit imposed with VLAN based networks. EVPN based VXLAN tunneled networks use BGP as control plane for L2 learning. … Continue reading Test-driving EVPN route publishing with GoBGP

Triggered remote packet capture using filtered ERSPAN

Packet brokers are typically deployed as a dedicated network connecting network taps and SPAN/mirror ports to packet analysis applications such as Wireshark, Snort, etc.

Traditional hierarchical network designs were relatively straightforward to monitor using a packet broker since traffic flowed through a small number of core switches and so a small number of taps provided network wide visibility. The move to leaf and spine fabric architectures eliminates the performance bottleneck of core switches to deliver low latency and high bandwidth connectivity to data center applications. However, traditional packet brokers are less attractive since spreading traffic across many links with equal cost multi-path (ECMP) routing means that many more links need to be monitored.

This article will explore how the remote Selective Spanning capability in Cumulus Linux 3.0 combined with industry standard sFlow telemetry embedded in commodity switch hardware provides a cost effective alternative to traditional packet brokers.

Cumulus Linux uses iptables rules to specify packet capture sessions. For example, the following rule forwards packets with source IP 20.0.1.0 and destination IP 20.0.1.2 to a packet analyzer on host 20.0.2.2:
-A FORWARD --in-interface swp+ -s 20.0.0.2 -d 20. Continue reading
