IPv6 Management Features IP Preserve for IPv6 To verify how IP Preserve was implemented in a switch, after the switch reboots, enter the show run command. Figure 5-11 shows an example in which all configurations settings have been copied into the startup-config file except for the IPv6 address of VLAN 1 (2001:db8::214:c2ff:fe4c:e480) and the default IPv6 gateway (2001:db8:0:7::5), which were retained. Note that if a switch received its IPv6 address from a DHCP server, the "ip address" field under "vlan 1" would display: dhcp-bootp.

If a switch's current IP address was acquired from a DHCP/Bootp server, the IP Preserve statement is ignored and the IP addresses in the downloaded configuration file are implemented. Figure 5-11.

IPv6 Management Features
IP Preserve for IPv6
To verify how IP Preserve was implemented in a switch, after the switch
reboots, enter the
show run
command. Figure 5-11 shows an example in which
all configurations settings have been copied into the startup-config file except
for the IPv6 address of VLAN 1 (2001:db8::214:c2ff:fe4c:e480) and the default
IPv6 gateway (2001:db8:0:7::5), which were retained.
Note that if a switch received its IPv6 address from a DHCP server, the “ip
address” field under “vlan 1” would display:
dhcp-bootp
.
