Write your own grapher script (replacement for routers2.cgi) and use a
CDEF to set the values to UNKNOWN during those undesired time range.

AFAIK rrdtool won't use the unknown intervals for average computation.

Read the rrd-users archive, the tutorial, the faq and many more resources
on the internet (e.g. try google) for more help on CDEF.
