Subject: [pcp] Doubt regarding port consumption protection

Dear all,

I have a doubt regarding the following aspect: (in chapter 10.5, page 44, 2nd paragraph)

PCP provides some protections against such port
   consumption: When a PCP client first acquires a new IP address (e.g.,
   reboots or joins a new network), it SHOULD remove mappings that may
   already be instantiated for that new Internal Address.  To do this,
   the PCP client sends a MAP request with protocol, internal port, and
   lifetime set to 0.

Specifically thinking in the PCP Client side, does it mean that the PCP Client, in the aforementioned condition, should send a deletion request and wait for its response before it sends any additional request?

Thanks in advance,

Felipe
