Unfortunately, there are implementations that don't support it.<br>

So you already have separate CHILD_SAs for these (possibly initiated by<br>
the peer, or narrowed by it). But to make this work properly your<br>
config has to reflects that.<br>

Single CHILD_SAs are rekeyed, but the complete local CHILD_SA config is<br>
used for the proposal (i.e. multiple TS if that's what you have<br>
configured locally). If a responder that doesn't support multiple TS<br>
doesn't consider the TS of the rekeyed CHILD_SA, but just blindly uses<br>
the first proposed TS, that's problematic (i.e. you must change the<br>
config to reflect that limitation).<br>
