Description

Configure a dynamic tunnel between two PE routers.

Note:

ACX Series routers do not support the gre statement.

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.
