IP Tunneling

  • Support for IPv4 and IPv6 unicast IP-over-IP tunneling (QFX5000)—Starting in Junos OS Release 21.1R1, we support IP-over-IP tunneling for IPv4 and IPv6 traffic on QFX5000. QFX5000 switches also support recursive route resolution for IP-over-IP tunnels.

    [See Overview of Next-Hop-Based Dynamic Tunneling Using IP-Over-IP Encapsulation.]

  • Support for BGPoverBGPoverBGP recursive route resolution (QFX5100, QFX5110, QFX5120, QFX5200, and QFX5210)—Starting in Junos OS Release 21.1R1, you can enable BGPoverBGPoverBGP route resolution by creating an expanded route hierarchy, using the preserve-nexthop-hierarchy statement at the [edit routing-options resolution] hierarchy level.
