How to Use This Image (GNS3 / EVE-NG / QEMU)
Unlike physical hardware where you copy the .bin to flash, virtualization requires specific configuration.
- Dynamic Routing: Full support for BGP (including address-families for VPNv4), OSPFv2/v3, EIGRP, and RIP.
- MPLS & L3 VPNs: This is a standout feature. Version 15.4.2T is stable enough to run MPLS LDP, MP-BGP, and VRF-Lite configurations for CCIE Service Provider studies.
- Security Features: Zone-Based Firewall (ZBF), IPSec tunnels (GRE over IPsec, DMVPN), and Control Plane Policing (CoPP).
- Management: SSHv2, SNMPv3, NETCONF, and RESTCONF (limited).
