BIG-IP SSL when serves as a SSL client and the ciphers used are ECDHE_ECDSA or DHE_DSS, it will send a bad client key exchange to SSL server in server initiated renegotiation.
SSL handshake failed. The SSL server may reset the SSL connection with an error: digest check failed, or ssl handshake failed.
BIG-IP acts as a SSL client and the ciphers used are ECDHE_ECDSA or DHE_DSS in server initiated renegotiation.
Do not use ciphers ECDHE_ECDSA or DHE_DSS.
BIG-IP SSL now works well with ciphers ECDHE_ECDSA or DHE_DSS in server initiated renegotiation where BIG-IP acts as a client.
