Give `river` a dedicated RDMA VF and two RSTP trunk attachments. Keep client services on the router VIPs and carry Digiweb VLANs over both switch paths. Set VF trust, multicast reception, bridge MAC and ARP behavior for local switching. Wait for Kea interface readiness and apply RSTP costs through `mstpd` despite port-registration and rename races. Load `palace`'s RAID module in the initrd. Record RouterOS and RouterBOOT upgrades and validate port, carrier and switch outages. Document the deployed architecture, interface handoffs and recovery procedures. Add physical socket maps, NIC capacities and cable connections alongside the logical topology and failover checks.

Home site
The home network (domain h.nul.ie): a redundant pair of routers in front of a VM host, an
NVMe-oF storage target, an IoT container host, and a workstation. The two routers — river (a VM)
and stream (a physical box) — are built from one shared
routing-common definition as an active/backup VRRP
pair, and everything clients touch (gateway, DNS) is a floating VIP that follows the master.

Router VIPs
Clients use per-VLAN floating VIPs as their gateway and DNS server; keepalived moves them between
river and stream. The addresses, DHCP/RA behavior and failover mechanics are documented once in
Router VIPs and Router HA.
Networks
The site separates core management, high-MTU trusted traffic, general trusted traffic, untrusted
clients and the two WAN paths. VLAN IDs, prefixes, MTUs and router addressing live in the canonical
home section of networking.md.
Switch fabric
The boxes hang off four hand-configured switches: jim and dave (MikroTik, RouterOS), brian
(Ubiquiti, UniFi), and the L2-managed Zyxel switch shytzel. They are not managed by this
flake. The physical topology, VLAN map, the Digiweb WAN path (trunked VLAN 10 + PVID 140 at the ONT
edge), and the multi-ONT plan are documented in switches.md. Router attachments
are described in Router HA; tested failure scenarios and checks
for maintenance are documented in router-failover.md.
Wireless APs
The Wi-Fi APs — vibe (MikroTik cAP ax) and wave (Cudy AX3000 on OpenWrt) — are dumb APs, also
not managed by this flake. The shared VLAN-trunk design, SSIDs, per-AP management addressing,
and the OpenWrt flash/config for wave are in aps.md.
5G WWAN
A Quectel RM500U-EA USB modem with a GoMo SIM is being evaluated as a replacement for stream's
Virgin Media WAN. It is bench-tested only and not yet referenced by the flake; the module settings
it needs, the APN gotcha and the CGNAT consequences are in wwan.md.
