Re: ipv6 dhcp server

Networker0 · ‎09-25-2020

I have an ipv6 dhcp configuration in my old ASR 1001 and I want to reconfigure it in ASR 1002 , but when I taped the configuration I found that there is some commands are missed .

this is the IPV6 DHCP configuration in ASR 1k :

####################################

ipv6 dhcp pool VLAN10-pool2
prefix-delegation pool wan_internet_BT
address prefix 2004:20::/64
address prefix 2004:20::/56 lifetime 315360000 315360000
link-address FE80:1::1/64
dns-server 2001:4860:4860::8888
dns-server 2001:200::10:64:16:4
dns-server 2A01:6E00:10:401::56
domain-name lab.mystrotv.com
sntp address 2001:4::1002
vendor-specific 3561
suboption 1 ascii "http://ssm.val:1111/ACS-INTF"
suboption 234 ascii "TWC"
suboption 23 address 2001:200::10:64:16:4
suboption 24 ascii "home"

and this what I could configure it in the ASR 1002:

ipv6 dhcp pool VLAN10-pool2

prefix-delegation pool wan_internet_BT

dns-server 2001:4860:4860::8888
dns-server 2001:200::10:64:16:4
dns-server 2A01:6E00:10:401::56
domain-name lab.mystrotv.com

as you see here , I couldn't configure the prefix-address command under the ipv6 dhcp server in my ASR 1002 and many other command .

Can you a post-show the version of both to check is there any syntax changed from the version. ( instead of copy and paste)

try each line to see any errors you encounter.
