Hi Randy, /etc/network/interfaces has nothing to do with FRR. I'd try a Debian forum. Taking a stab in the dark: have you installed the ifupdown2 package or are you using the ifupdown package? ifupdown doesn't support the vrrp keyword. FWIW, I get an identical error message from Bookworm. "iface something" without a method such as static or manual gives that error. AFAICT, the "vrrp" keyword is unhandled by ifupdown, so its presence in /etc/network/interfaces should be a noop. What results do you get from: ifconfig eno1 ip -6 link show eno1 ip -6 addr show eno1 I don't use VRRP on Debian so unfortunately I may not be able to help you directly. There does appear to be support for it in keepalived that doesn't appear to touch /etc/network/interfaces. Intuitively, I would expect the /etc/network/interfaces configuration to bring up the non-vrrp configuration on the interface while whatever you use to manage VRRP handles the VRRP details.
