I think that you can replace the above three lines by simply:
if expr X"$OVSDHCPINTERFACES" : X".*\b${INTF#ifcfg-}\b" >/dev/null; then
or this might be more readable assuming you want commas to separate
interfaces in $OVSDHCPINTERFACES:
case $OVSDHCPINTERFACES in
${INTF#ifcfg-} | \
"${INTF#ifcfg-},"* | \
*",${INTF#ifcfg-}" | \
*",${INTF#ifcfg-},"*)
BOOTPROTO=dhcp ${OTHERSCRIPT} ${CONFIG}

I think that
BOOTPROTO=dhcp ${OTHERSCRIPT} ${CONFIG}
is probably a better way to express it, so that BOOTPROTO does not
continue to be set. (Unless you want that?)

It is easier to write:
OVSINTF=$CONFIG /sbin/ifup "$OVS_BRIDGE"
rather than the above three lines.
Similarly in the second case.
Thanks,
Ben.
