I mean really simple. Like 2000::/3. If it's not in there it's bogon, yes ?
Been using that on the advanced networks side for ... OK, years. Seems to
work. Kept unseemingly bogons like 1000::/3 out, except for the
deprecated 6bone pTLA, 3FFF::
What I'm really asking, is for folks thoughts on using this - is it too
restrictive ?
For leaks of old 6bone space, which I haven't seen for a long while,
probably not. But filter aginst that, and maybe it will be fine. It's
all in the RIR allocations....
How long until it's obsolete ?
Should be a really long time no ?
Mmm...Last table entry in my table is: 2C0F:FE18::/32. Maybe 2000::/4
will do, but that might not last very long as an ACL, given the proximty
of 2Cxx:: to 2FFF::
Again, just looking for some feedback either way. Would be very nice to have
a single line ACL do this job.
