Release Information
Statement introduced in Junos OS Release 17.3R1 on the MX Series.
Description
Configure dynamic IPv4-over-IPv6 tunnels and define their attributes to forward IPv4 traffic over an IPv6-only network. IPv4 traffic is tunneled from customer premises equipment to IPv4-over-IPv6 gateways. You must also configure extended-nexthop option at [edit protocols bgp family inet unicast] hierarchy level to allow BGP to route IPv4 address families over an IPv6 session.
Options
gre—Enable dynamic
generic routing encapsulation type tunnel mode for IPv4
Values:
next-hop-based-tunnel—Enable next hop base dynamic-tunnel for steering IPv4 traffic with IPv6 next hop address.
source-address—Specify the source address of the tunnel.
The remaining statements are explained separately. See CLI Explorer.
Required Privilege Level
