[strongSwan] Query on Child SA Creation

Thanks for the update

One more observation related to this .

If I set reuse_ikesa=no then for bringing up the connection I can use "ipsec up" without the "{ }" suffix in the connection name. But I see that for bringing down the connection I need to specify the connection name with { } suffix otherwise the connection does not terminate.   

Is this the known behavior ?

Regards
Shyam

You can initiate/terminate specific CHILD_SAs using curly brackets, e.g.
ipsec down connxy{}.

Configurations from ipsec.conf get merged if the IKE_SA specific
parameters match (i.e. identities and addresses).

To initiate each CHILD_SA in a seperate IKE_SA, you may specify the
strongswan.conf option charon.reuse_ikesa = no.
