Hi,

interface Vlan100

 ipv6 address x:EA00:3561:1:x:246:236:102/125
#
(config-if)#standby 100 ipv6 ?
X:X:X:X::X IPv6 link-local address
X:X:X:X::X/<0-128> IPv6 prefix
autoconfig Obtain address using autoconfiguration

(config-if)#standby 100 ipv6 x:ea00:3561:1:x:246:236:103
% Incomplete command.

(config-if)#standby 100 ipv6 x:ea00:3561:1:x:246:236:103/128
% Group configured for different address family

How should I do?

Thank you very much.

Hi there,

Although you don't show it in your config, it looks like you are sharing the standby group number between both protocols. You should for example use standby 99 for IPv4 and standby 100 for IPv6:

!
int vlan100
  standby 99 ip 192.168.1.254
  ..
  standby 100 ipv6 2001::aaaa:1/64
  ..
!

cheers,

Seb.
