R1 - is a DHCPv6 server
R4 - is a Client

*Problem is R4(Client) is indeed receiving prefix from R1(Server) but can
not see in show ipv6 int brief..what could be problem..please see my configs
below *

*R1 Config*
*
*
R1#sh run int fa0/1
Building configuration...

Current configuration : 143 bytes
!
interface FastEthernet0/1
 no switchport
 no ip address
 ipv6 address 2001:123::1/64
 ipv6 dhcp server DHCPPOOL rapid-commit allow-hint
end

R1#
*R1#sh run | in ipv6*
ipv6 unicast-routing
ipv6 dhcp pool DHCPPOOL
 ipv6 address 2001:123::1/64
 ipv6 dhcp server DHCPPOOL rapid-commit allow-hint
ipv6 local pool POOL 2001:123::/48 64

*R1#sh run | s dhcp*
ipv6 dhcp pool DHCPPOOL
 prefix-delegation pool POOL
 dns-server 2222::1

R1#

R4(config-if)#do sh run int fa0/4
Building configuration...

Current configuration : 121 bytes

 no switchport
 no ip address
 ipv6 enable
 ipv6 dhcp client pd DHCPCLIENT rapid-commit
end

R4(config-if)#

R4(config-if)#do sh ipv6 int fa0/4
FastEthernet0/4 is up, line protocol is up
  IPv6 is enabled, link-local address is FE80::CE03:17FF:FEA0:F004
  No global unicast address is configured
