Hello,

I'm trying to configure BGP with FRR (Version 1.36_1) and I'm having some issues. Maybe someone can help me?

I have 2 OPNsense (HA) with their own internet connections using BGP. If the internet connection of the primary OPNsense fails, it should switch to the secondary using BGP. This works fine with IPv4, but it doesn't work with IPv6.

Thank you for your help
