*IJDCN – Introduction to Juniper Data Center Networking*
This course lays the foundational knowledge necessary to understand a data center that is built upon an IP fabric, but does not include Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) architecture.
This course covers Ethernet switching, VLANs, Layer 2 security features, routing policies, link aggregation, load balancing, filter-based forwarding (FBF), routing instances, BGP, graceful restart, and bidirectional forwarding detection (BFD).
