Linux Bonding, LLDP, and MAC Flapping
Sometimes a painfully troublesome networking problem can have a complicated and brain-twisting root cause, one which you dread having to explain to peers and managers. However, sometimes the root cause is dead simple and makes you feel silly for how long it took you to find it. Today, I had one of the latter and […]

In the last blog post in the VLANs and VRFs in netlab series, I described how we can combine VLANs and VRFs and create a VRF Lite solution with stretched VLANs. Wonder how hard would it be to create a routed multi-hop VRF Lite topology? It’s trivial.

Worth Exploring: NetDoc – Automated Network Discovery and Documentation
Andrea Dainese released an interesting tool that performs automated network discovery, pushes the discovered data into NetBox, and then uses netbox-topology-views plugin to create network topology diagrams.
Definitely worth exploring!

After decades trailing the rest of the world in leading-edge chip making, Chinese sand stamper Semiconductor Manufacturing International Corporation (SMIC) has quietly got into the 7nm business. That’s a huge and unexpected leap. Has the West’s embargo of the latest fab furniture failed?

Although the United States and China are not engaged in traditional warfare, they are engaged in a war of ideas, trade, and technology, especially in semiconductor hegemony, where both sides are battling for supply and advancement.

Trade was global, the world was inextricably connected, and your job’s in China now but you should thank us, actually, because everything is cheap and fast and out-of-work factory workers can simply learn to code.

Fun Times: Is Cisco ACI Dead?
A recent blog post by Andrew Lerner asks whether Cisco ACI is dead. According to Betteridge’s law of headlines, the answer is NO (which is also Andrew’s conclusion), but I liked this gem:
However, Gartner assesses that Nexus Dashboard Fabric Controller is the optimal fabric management software for most Cisco data center environments.
An automation intent-based system provisioning a traditional routed network is considered a better solution than a black-box proprietary software-defined blob of complexity? Who would have thought…
