Summary

New scripts/generate_traffic.sh: starts iperf3 -s on the DC gold-VRF
servers (dc-server2, dc-server4) and drives iperf3 -c clients from
the paired campus gold-VRF hosts (campus-host1, campus-host2),
exercising the full DC→Core→Campus stitched EVPN Type-5 path.
Live terminal dashboard (server list + per-client Mbits/sec, refreshed
every second) for the given duration; cleans up server-side processes
on exit/Ctrl-C.
Documented in scripts/README.md.

Without this, host containers sit idle and IPFabric ARP/MAC tables,
Grafana throughput graphs, and the weathermap panel stay empty until
someone manually generates traffic.

Closes #55

Test plan

Ran ./scripts/generate_traffic.sh 6 — live dashboard updated
per-second, both DC↔Campus sessions showed real Mbits/sec (~15-23
Mbits/sec)
Confirmed iperf3 -s processes were killed on both DC servers after
the run (pgrep iperf3 empty)
Optional: re-run against a longer duration and confirm IPFabric
Hosts table / Grafana throughput graphs populate from the traffic

## Summary - New `scripts/generate_traffic.sh`: starts `iperf3 -s` on the DC gold-VRF servers (`dc-server2`, `dc-server4`) and drives `iperf3 -c` clients from the paired campus gold-VRF hosts (`campus-host1`, `campus-host2`), exercising the full DC→Core→Campus stitched EVPN Type-5 path. - Live terminal dashboard (server list + per-client Mbits/sec, refreshed every second) for the given duration; cleans up server-side processes on exit/Ctrl-C. - Documented in `scripts/README.md`. Without this, host containers sit idle and IPFabric ARP/MAC tables, Grafana throughput graphs, and the weathermap panel stay empty until someone manually generates traffic.

Add iperf3 traffic generator for DC<->Campus gold VRF path 5b12894289

Host containers sit idle otherwise, leaving IPFabric ARP/MAC tables and
Grafana throughput graphs empty until someone manually generates traffic.
