-## Known weirdness
-
-MetalLB's BGP implementation is slightly stricter than the spec when
-it comes to CIDR prefixes. BGP encodes a prefix as a CIDR mask size
-and an IP address. Trailing bytes of the IP that are fully masked out
-are elided, but a partially masked byte is included in its
-entirety. RFC 4271 states "Note that the value of trailing bits is
-irrelevant."
-
-This makes parsing and encoding of UPDATE messages non-idempotent,
-because there are multiple valid encodings for the same prefix.
-
-For ease of fuzz testing, MetalLB's implementation rejects prefixes in
-UPDATE messages if they are not in "normal form", with the masked bits
-set to zero.
-
-If you encounter a BGP implementation that fails to interoperate with
-MetalLB because of this constraint, please file a bug.
