This post goes through the deployment of a HA pair of F5 BIG-IP LTMs in Azure. Like with most vendors the F5 solutions is documented as part of ARM templates, I personally prefer to pick these things apart and first build them manually to better understand what is going on under the hood.

Chinar Trivedi asked an interesting question about DHCP relaying in VXLAN/EVPN world on Twitter and my first thought was “that shouldn’t be hard” but when I read the first answer that turned into “wait a minute, how exactly does DHCP relaying works?”
