Hello Yasmeen,
for a Cisco multilayer switch to support IPv6 routing
you need
ipv6 unicast-routing
ipv6 cef
+
configuration under interface (routed interface or more likely SVI interface)
interface vlan 10
ipv6 address 2001:AAAA::/64 eui-64
However, these commands may be supported or not depending on the SDM template of the switch
You can check this with
show sdm prefer
If your current SDM template does not support IPv6 you need to change it and to reload the switch.
Later I will add how to make the switch to advertise DHVPv6 prefixes in router advertisements.
Ipv6 router advertisements are enabled by default the following command re-enable them
no ipv6 nd ra supress
Edit:
You may need the DHCPv6 relay agent feature
1. enable
2. configure terminal
3. interface type number
4. ipv6 enable
5. ipv6 dhcp relay destination ipv6-address [interface-type interface-number]
6. end
see
This should be configured on all L3 IPv6 interfaces not directly connected to the linux box acting as DHCPv6 server.
Hope to help

You would need the following on the customer facing interface.
inteface vlanxxx
ipv6 address 2001:DB8:12ff:1::1/64
ipv6 nd prefix 2001:db8:12ff:1::/64 no-advertise <++++++ This is to make sure SLAAC is not used.
ipv6 nd managed-config-flag
ipv6 nd other-config-flag
