The problem I faced was that the standard Linux bridges (usually used to simulate virtual p2p links between vMX-es won't forward BPDUs including LACP (and I did not find a way to hack around at that time) However then I started to use OVS instead of Linux bridges and there's a settings to enable BPDU forwarding and that did the trick. So what I had was all ~50 interfaces of all ~30 vMX-es connected to a single OVS where putting two ports on the same VLAN creates a virtual p2p link between a pair of interfaces/nodes (very easy to change topology add/remove links or nodes) -this OVS has BPDU forwarding enabled so now I can bundle any links between any two vMX-es I'm then using another OVS for the internal VCP-VFP connections, and another one for FXP interface and connectivity outside of the lab.
Disclaimer, I never used the juniper scripts to define and start VMs and connectivity, I created the VM configs and the whole lab setup myself (later automated with ansible). adam _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
