Step Command 8. Configure the maximum number of nested encapsulations of a encapsulation-limit [ number ] packet. 9. Return to system view. quit 10. Enable dropping of IPv6 packets using IPv4-compatible IPv6 addresses. tunnel discard ipv4-compatible-packet Remarks Optional. 4 by default. N/A Optional. Disabled by default. Configuration example Network requirements As shown in Figure 69, the two subnets Group 1 and Group 2 running IPv6 are connected through an IPv6 network. Configure an IPv6 over IPv6 tunnel between Switch A and Switch B to make the two subnets reachable to each other without disclosing their IPv6 addresses to the IPv6 network.
