You can configure a static route, and specify the local tunnel interface as the egress interface or specify the IPv6 address of the peer tunnel interface as the next hop. Alternatively, you can enable a dynamic routing protocol on both tunnel interfaces to achieve the same purpose. For the detailed configuration, see Layer 3-IP Routing Configuration Guide. • The destination address of the route passing the tunnel interface must not be on the same subnet as the destination address configured for the tunnel interface. To configure an IPv6 over IPv6 tunnel: Step Command 1. Enter system view. system-view 2. Enter IPv6 tunnel interface view. interface tunnel number [ mode ipv6 ] 3. Configure an IPv6 address for For configuration details, see the tunnel interface. "Configuring basic IPv6 settings." 4. Configure the source address or source interface for the tunnel interface. source { ipv6-address | interface-type interface-number } Remarks N/A N/A No IPv6 address is configured for the tunnel interface by default. By default, no source address or interface is configured for the tunnel. The specified source address or the IPv6 address of the specified source interface is used as the source IPv6 address of tunneled packets. 179
