IICTI Certified Routing and Switching Professional

Holders demonstrate that they can apply and evaluate advanced IGP design: OSPF/IS-IS areas, levels and fast convergence, bGP architecture, path selection and policy at scale, routing security and internet edge hardening and mPLS, segment routing and traffic engineering, plus 7 further areas, in realistic professional scenarios, as defined in the AQSCERT scheme for Routing and Switching Professional.
