Hi,

I notice that Figure 2 includes:

>      | GRASP M_FLOOD       |                   |                    |
>      |   periodic broadcast|                   |                    |

but this is not further specified.

If it is intended to be identical to the use of GRASP M_FLOOD for the
objective "AN_Proxy" in draft-ietf-anima-bootstrapping-keyinfra, there
should be an explicit note to that effect. If it's *not* the same "AN_Proxy"
objective, there is some more work to do.

Regards
   Brian Carpenter
