Configuring a GRE over IPv6 Tunnel
Only EB cards and SD cards support 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… Use the command… Remarks
