So unless configured otherwise, one > has to assume it's far more problematic than a non-ULA global. > Do you mean "no guarantee of symmetric routability"? The fact that the packet arrived in the first place seems to indicate earlier policy choices (e.g. the sender may not have a non-ULA global address, and the two /48s already seem to share a common definition of "site"). I am still relatively new to homenet and I am surely missing a lot of background. Has anyone discussed dealing with multiple /48 ULA prefixes in a single site?
