That's a somewhat philosophical question - IPv6 mandates(!) IPSEC support,
so protocol designers are doing the right thing in relying on established
crypto infrastructure that's supposed to be already there and well-tested,
instead of every one inventing their own scheme again and again.
Now, in real life, things tend to not work out that way - OSPFv3 is there,
IPSEC for IPv6 isn't. So who's to blaim, the protocol designers, or the
vendors that choose to implement only bits and pieces of the protocol
But anyway, I seem to remember that OSPF+IPSEC is there on IOS... FN
agrees with me:
"IPv6 Security: IPv6 IPSec to Authenticate OSPFv3"
"To use the IPsec AH, you must enable the ipv6 ospf authentication command..."
Now the interesting question is whether this is available in any reasonable
subset of IOS versions... the URL above claims it was added to 12.4(9)T,
and doesn't say a word about 12.2SX/12.2SR trains. FN says it was added
to 12.3(4)T, but nothing about 12.2SX/R or IOS XR/IOS XE either.
So, for the original poster, this won't help. (Please go to your BU and
complain that IOS feature distribution sucks big time...)
