Configuring a GRE over IPv6 Tunnel

EB boards and SD boards support only the GRE over IPv6 Tunnel.

Configuration Prerequisites

Interfaces on a device, such as VLAN interfaces, and loopback interfaces, are configured with IPv6
addresses and can communicate. These interfaces can serve as the source of a virtual tunnel interface
to ensure the reachability of the destination address.

Configuration Procedure

Follow these steps to configure a GRE over IPv6 tunnel:
To do...
Enter system view
Enable the IPv6 packet
forwarding function
Use the command...
system-view
ipv6
1-41
