# ptsd-migration.yml — PPPoE to super DHCP (phase 0: connectivity prove-out)
# Goal: reliably connect to DEV2 using:
# 1) direct LLDP IPv4 (10.x) if available and auth works
# 2) tunnel via DEV1 (default / primary)
# 3) LLDP IPv4 (10.x) fallback if tunnel auth fails
# 4) LLDP IPv6 fallback via DEV1 (nested ssh to [ip6%iface]) if all else fails
#
# Focus: reliable connectivity to DEV2
# Paths:
# A) direct LLDP IPv4 (10.x) if available and auth works
# B) tunnel via DEV1 (default)
# C) LLDP IPv4 (10.x) fallback if tunnel auth fails
# D) LLDP IPv6 fallback via DEV1 (nested ssh to [ip6%iface]) if all else fails
# After connection: run "uptime" on DEV2 and print it.
