• The tunnel destination address specified on the local device must be identical with the tunnel source address specified on the tunnel peer device. • The tunnels in the same mode on a device must not use the same tunnel source and destination addresses. • If the destination IPv6 network is not in the same subnet as the IPv6 address of the tunnel interface, you must configure a static route destined for the destination IPv6 network. You can 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 detailed configuration, see Layer 3-IP Routing Configuration Guide. To configure an IPv6 over IPv4 manual tunnel: Step Command Remarks 1. Enter system view. system-view N/A 2. Enter IPv6 over IPv4 manual tunnel interface view. interface tunnel number [ mode ipv6-ipv4 ] N/A 3. Specify an IPv6 address for the tunnel interface. For configuration details, see No IPv6 address is configured for "Configuring basic IPv6 settings." the tunnel interface by default. 4. Configure a source address or source interface for the tunnel source { ip-address | interface. interface-type interface-number } By default, no source address or source interface is configured for the tunnel interface. The specified source address or the primary IP address of the specified source interface is used as the source IP address of tunneled packets. 5. Configure a destination address for the tunnel interface. destination ip-address By default, no destination address is configured for the tunnel interface. The tunnel destination address must be the IP address of the receiving interface on the tunnel peer. It is used as the destination IP address of tunneled packets. 6. (Optional.) Set the DF bit for tunneled packets. tunnel dfbit enable The DF bit is not set for tunneled packets by default. 7. Return to system view. quit N/A 8. (Optional.) Enable dropping of IPv6 packets using IPv4-compatible IPv6 addresses. tunnel discard ipv4-compatible-packet This feature is disabled by default. Configuration example Network requirements As shown in Figure 73, configure an IPv6 over IPv4 tunnel between Switch A and Switch B so the two IPv6 networks can reach each other over the IPv4 network. Because the tunnel destination IPv4 address 164
