Design and implement advanced BGP policies (path selection, community strings, filtering).
Design, configure and maintain the MPLS core, including LDP/RSVP-TE and deployment of L3 VPN services (VRFs) and L2VPNs (VPLS/VPWS) for enterprise customers.
Perform Traffic Engineering (TE) using RSVP-TE to ensure deterministic paths and apply QoS policies (DiffServ over MPLS) to prioritize critical services (voice and video).
Implement high-availability and fast-convergence mechanisms such as BFD (Bidirectional Forwarding Detection) and MPLS FRR (Fast Reroute) to meet maximum SLAs (five nines).
Manage edge routers (Provider Edge
PE) and Carrier-Grade NAT (CGN) solutions and plan the transition to IPv6 (Dual Stack or DS-Lite).
Lead resolution of complex incidents involving packet loss, microbursts, high latency and protocol failures (BGP session flapping, OSPF/ISIS adjacency issues).

Bachelor's degree in Electronic Engineering, Telecommunications, Information Technology or a related field.
External routing; BGP (Border Gateway Protocol); strong command of iBGP, eBGP, Route Reflectors (RRs), advanced path selection policies, attribute manipulation (AS_PATH prepending, MED, Local Preference) and use of community strings.
MPLS core; MPLS and VPNs; proven experience with LDP and RSVP-TE. Configuration and operation of L3 VPNs (M-BGP and VRFs) and L2VPNs (VPLS, VPWS or Ethernet VPN
EVPN).
Interior routing; IGPs (OSPF or IS-IS); proficiency in hierarchical area design, metric optimization and ensuring fast convergence. Preferably experience with IS-IS.
High availability; resiliency and convergence; practical knowledge of MPLS FRR, BFD and use of Non-Stop Routing (NSR) or Graceful Restart (GR).
Hardware; carrier-class routers; hands-on configuration experience with high-capacity routing platforms (e.g., Cisco NCS/ASR lines, Juniper MX Series, or Huawei/Nokia platforms).
Addressing; IPv4 and IPv6; scalable addressing planning. Knowledge of IPv6 transition strategies (e.g., Dual Stack, DS-Lite, NAT444).
QoS and TE; Quality of Service; configuration of DiffServ models over MPLS, policing, shaping and traffic classification for services with SLAs.
