w60-dish — 60 GHz PtP dish

A 60 GHz point-to-point dish pair (e.g. w60-fenwick-holmes ↔ w60-holmes-fenwick). See 60 GHz wireless for products, MTU and recovery.

Role	radio — documented, not configured
Platform	(empty) — keeps the dishes out of the automation inventory
Interfaces	ether1 (2.5gbase-t) + radio (ieee802.11ad)

The dishes are modelled in NetBox for monitoring, DNS and cabling (wireless link objects), but Ansible never configures them — they are on the hands-off list.

What the routers derive

On each dish-facing router port (metro-pe):

• ros_role=core-link, ospf_cost=500 (policy — the port is Ethernet, so the cost is set manually), bfd_enabled=true, and its half of the /31.
• The gateway router additionally gets a virtual radio-mgmt child (parent = the dish-facing port, untagged VLAN 99, IP 10.254.250.1/29). The transport role builds the VLAN interface + gateway and advertises the /29 into iBGP. The repeated VLAN 99 never collides because it is per-parent-port.

ether1 on the dish itself takes the primary IP (.2/.3 of the /29, gateway .1) with a dns_name.

One-time hand-config on the dishes

• Bridge mode end-to-end.
• Management VLAN 99, addresses .2 / .3, gateway .1.
• The radio must pass tagged frames at ≥ 1600 L2MTU (the MPLS floor) before MPLS is enabled on the link — verify before turning up the overlay.
