Description
Configure a dynamic tunnel between two PE routers.
ACX Series routers do not support the gre statement.
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
| bgp-signal |
Enable the creation of a tunnel signaled by BGP. |
| gre |

|
| source-address |
Specify the source address of the tunnel. |
tunnel-name |
Name of the dynamic tunnel. |
The remaining statements are explained separately. See CLI Explorer.
