On my patch  numeric IPv6 address (every way) are  solved at least for
cfgmaker

But not for mrtg (it crash by reading in the mrtg.cfg the dotted address
).

	$data = eval($$rcfg{target}{rou});   at around +405

I had left it stand-by two weeks ago when I saw your patch was beeing
integrated into the 2.10.0pre1.

Yes , the patch corrects the parser.
, but then I have the same problem
when
I try:

cfgmaker  --enable-ipv6 public@[2001:618:10:2a03:205:1cff:fe00:1df0]
