Platform and Infrastructure

Support for next-hop-based dynamic tunnels (cRPD)—Starting in Junos OS Release 21.2R1, you can configure next-hop-based dynamic IP tunnels in the Linux kernel to provide a private and secure path on a public network. By default, MPLS-over-UDP tunnel is preferred over GRE tunnels. We support the following dynamic tunnels:

• GRE
• MPLS over UDP

[See Next-Hop-Based Dynamic Tunnels, Configuring Next-Hop-Based MPLS-Over-UDP Dynamic Tunnels, and Dynamic Tunnels Overview.]

EVPN over VXLAN encapsulation (cRPD)—Starting in Junos OS Release 21.2R1, we support the Layer 2 EVPN over VXLAN functionality.

[See EVPN with VXLAN Data Plane Encapsulation and MAC-VRF L2 services.]
