and what's your rex.awk look like?

Did you change pat2move to 2move
or did you add a space pat 2move?
--
Here is a more sophisticated solution:
Code:
awk '
 BEGIN {
   lineBelow="<td>[[Cisco]]</td>"
   pat2move="TYPE *= *Router"
   scope=8
 }
 ($0==lineBelow) {n=scope; print; next}
 (n==0) {print; sep=""; next}
 ($0~pat2move) {print $0 RS save; n=0; next}
 {save=save sep $0; sep=RS}
 (--n==0) {print save}
 END {if (n>0) print save}
' fileA.txt

The pat2move is a RegularExpression: a * means the previous character is present zero or more times.
E.g the TYPE *= *Router matches
Code:
TYPE =Router

and
Code:
TYPE     = Router

. You can also put a character class like TYPE[[:space:]]*=[[:space:]]*Router.
scope is the number of following lines to search for the pat2move.
The lineBelow is a string to be compared with the whole line.

I think this is a lot easier in ed than in awk. Try:
Code:
ed -s file <<-EOF
	g/^TYPE[[:blank:]]*=[[:blank:]]*Router/.m?<td>[[][[]Cisco[]][]]</td>?
	w
	q
EOF
