From the BGP session all the way to the forwarding decision — how do you actually trace an EVPN route step by step through Junos? This deep dive walks you through a demo fabric across all the relevant routing tables, complete with the matching show commands.
How does Apstra turn EVPN, VXLAN, and IRB routing into real Junos configuration? This deep dive breaks down tenants, VNIs, and host attachment to show how the overlay truly works under the hood.
Apstra abstracts a lot – but those who truly understand DC fabrics look under the hood. This post dissects the underlay design of a Juniper 3-stage Clos fabric: from IP addressing to eBGP with individual spine ASNs and the BGP policies that prevent routing loops.
