# 982 — IPv6 apply script (ROS 7.21.4, BGP-only / no OSPFv3)
|
|
# =============================================================================
|
|
#
|
|
# 982 is a leaf tower. Single backbone P2P:
|
|
# * core (north) — ether7-380 (60 GHz), v6 P2P 2606:1c80:0:14::/64 (982 .2)
|
|
# Default upstream toward core via :14::1.
|
|
#
|
|
# Loopback: 2606:1c80:0:10::110/128
|
|
# /44 customer aggregate: 2606:1c80:1300::/44
|
|
# Mgmt LAN: 2606:1c80:1300::1/64 (assumes `mgmt` bridge — verify name first).
|
|
# PPPoE profile assumed `pppoe`. Customer interface-list assumed `customer`.
