Does anyone know how FRR treats “fd80” prefixes? My configuration uses “fd80” prefixes as Unique Local IPv6 Unicast Addresses (IETF RFC 4193), which can be routed. But, somehow, FRR changes these “fd80” addresses to “fe80”.
A (sanitized?) configuration snippet/example from your set-up will help you get relevant answers ;)
For a side note, I can mention DN42 (1) uses fc00::/7 space (0), with different participants using a mix of whatever you can find (FRR, Bird1/2, XORP, Quagga, EdgeRouter, Mikrotik, OpenBGPd, IOS, IOS-XR, JUNOS, etc.) [0]: fc00:0000:0000:0000:0000:0000:0000:0000 - fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff [1]: https://dn42.us Cheers, Chriztoffer
