|
# Newhope is a relay tower. P2Ps:
|
|
# * core (north) — ether2-380, v6 P2P 2606:1c80:0:13::/64 (newhope .2)
|
|
# * lowry (south) — ether6-lowrycrossing, v6 P2P 2606:1c80:0:18::/64 (newhope .1)
|
|
# Default upstream toward core via :13::1.
|
|
# Lowry's loopback :10::109 is reachable through the :18::/64 link (lowry
|
|
# is dual-homed only via newhope today).
|
|
#
|
|
# Loopback: 2606:1c80:0:10::108/128
|
|
# /44 customer aggregate: 2606:1c80:1800::/44
|
|
# Mgmt LAN: 2606:1c80:1800::1/64 — assumes a `mgmt` bridge (verify with
|
|
# /interface/print before applying).
|
|
# PPPoE profile assumed `pppoe`. Customer interface-list assumed `customer`.
