Hi!
We are trying to setup an IPv6 DHCP-Server on a Cisco 878 (c870-advipservicesk9-mz.124-15.T13.bin). There is another problem with the availability of the router. When you boot the router, he is broadcasting the IP-addresses but after about 30 minutes he going “stealth”. He doesn´t broadcast any more and he is not reachable via ping. Only a reboot can “solve” the misery/situation.
Do you have any guess/clue?
Here is a part of the code:
-------------------------------------------------------------------
!
ip name-server 2001:XXX:XXXX:6::53
!
ipv6 unicast-routing
no ipv6 source-route
ipv6 cef
ipv6 dhcp pool dhcppool
prefix-delegation 2001:XXX:668::/48 0007
dns-server 2001:XXX:XXXX:6::53
dns-server 2001:XXX:XXXX:6:0:153:235:53
domain-name blablabla.com
!
!
interface Loopback0
no ip address
ipv6 address 2001:XXX:668:111::1/128
ipv6 enable
!
interface Vlan20
ip address 10.X.X.1 255.255.255.0
ipv6 address 2001:XXX:668:1::1/64
ipv6 enable
ipv6 dhcp server dhcppool
!
ipv6 local pool dhcppool 2001:XXX:668::/48 50
