When using certificates I always use ASN1_DN for srcid and dstid. It
should look something like this:

srcid "/C=DE/ST=Lower
Saxony/L=Hanover/O=OpenBSD/OU=iked/CN=185.21.22.23/emailAddress=reyk@openbsd.org
" \
dstid "/C=DE/ST=Lower
Saxony/L=Hanover/O=OpenBSD/OU=iked/CN=p7.local/emailAddress=reyk@openbsd.org"
\

(I have never used "ikectl ca", so I'm not sure what the files a called.
But with something like this you should be able get the srcid/dstid-lines:
openssl x509 -subject -noout -in 185.21.22.23.crt
openssl x509 -subject -noout -in p7.local.crt)
