[c-nsp] mgre dilemma

[matt carter]

hi all,

i should have mentioned also (my bad) i already have mgre between 6 x sup720
(12.2 SXF) working just fine, it has only when i have gone to add a 7301 to
the mix i have realised the 7301 (12.2S) wont bring up the mgre without a
key, but the sup720's wont take a key without dropping to software
switching. so im damned if i do and damned if i dont.. the workaround for
now has been to use individual gre tunnel's which doesnt require key and
enables hardware switching on the sup720 end..

any advice appreciated..
