Tom: > ILA is not NAT! :-)
As seen from the end point, I agree ILA is not NAT. But, that the function that is needed at two places where you do translation of the addresses from SIR to LOCATOR, or LOCATOR to SIR is a NAT function, and you have a mapping state similar to NAT state. That¹s a NAT :-) Sri On 3/20/18, 4:29 AM, "dmm on behalf of Tom Herbert" <[email protected] on behalf of [email protected]> wrote: >On Tue, Mar 20, 2018 at 3:57 AM, Lyle Bertz <[email protected]> wrote: >> We'll be quite time constrained during this session so I thought I >>would ask >> a couple of simple questions which I hope have already been addressed in >> previous e-mails: >> >> 1.
