Hi, yogijain, renew the HCIE-R&S certificate rule:
Before the certificate expires, pass any current HCIE Written/HCIE Lab/HCIE Interview of the ICT infrastructure certification type.
http://support.huawei.com/learning/Certificate!toRecertification?lang=enYou can renew the HCIE certificate only by passing any one of the HCIE written exams. Now we have released five HCIE directions(English version) : HCIE-R&S, HCIE-Storage, HCIE-Cloud, HCIE-EC, HCIE-Data Center. you can choose one to pass the written exam and the validity period of the certificate will be extended.
Thanks for your support.
