# Climax sits between verona (south-west) and the rest of the network
|
|
# (via core). One v6 default upstream — toward core via :12::1.
|
|
#
|
|
# P2P interfaces:
|
|
# ether4-380-airfiber24 :12::/64 (climax .2, core .1)
|
|
# ether6-verona-11ghz :20::/64 (verona .1, climax .2)
|
|
# ether3-culleoka-11ghz :21::/64 (climax .1, culleoka .2)
|
|
# ether5-494 :17::/64 (climax .1, 494 .2)
|
|
#
|
|
# Mgmt LAN: bridge `mgmt`, v6 = 2606:1c80:1100::1/64
|
|
# PPPoE customers: profile name `pppoe`, customer pool 2606:1c80:1101::/48 → /56
|
|
#
|
|
# BFD on wireless OSPFv2 templates was already turned off on this router
|
|
# earlier today (2026-05-09) — verified via the freshly-pulled climax.rsc.
|
|
# No BFD changes here.
