Sophos Firewall: OSPF neighborship stuck in INIT/DROTHER state

Hello Vishal,

thanks for your update. A higher multicast limit solves my issue:

set routing multicast-group-limit 300

Sophos Firewall: Change multicast group limit for OSPF

BTW: Which VPN technology is best-practice: RBVPN or RED-Tunnel

Hi Ben@Network : Thank you for sharing the latest feedback on this. For RBVPN or RED tunnel, it may depend on which type of traffic you wanted to pass via the tunnel. Both are different technology where we may choose any one of them based on setup and requirements.
