Echoing what others have said.
Depending on the router vendor you work most with - sometimes some of the more advanced platform bits are useful.
Like the Juniper path the Nokia[sic Alacatel-Lucent] SRA - Service router associate path is similarly useful; IF you work with the 7xxx series a�� lot. Also they will give you credit for Juniper/Cisco 100/200 level stuff you might have done previously.
Personally like others I put no stock in Cert's - I've done a chunk of the courseware for said SRA and some other vendors bits, but you wouldn't find me ever sitting an exam or committing to a track.
Also some of the Redhat training is very good as well, if you work with OVS/Linux routing and Virtualisation they have some good content, and their trainers are generally very good in my experience.
Disclaimer I work for Nokia, but my observations are my own.
