IPv6 prefix assignment problem

Hi,

We have following configuration for ISC DHCPv6:

omapi-port 8913;

option dhcp6.info-refresh-time 129600;
option dhcp6.aftr-name code 64 = string;

deny duplicates;
one-lease-per-client on;

   option dhcp6.name-servers 2a01:c840:110:c000::10 , 2a01:c840:130:c000::10 ;
}

I am testing following scenarion:

- two relay agent exists (one for subnet1 and second from subnet 2)

- i try to migrate device from subnet2 into subnet1. I suppose that i will get another prefix delegation. But as you can see in the debug messages, it doesnt work.

Could you help me please? Thx

Re: IPv6 prefix assignment problem

As I see it, you have no restrictions on either subnet so DHCP is
free to allocate from either one.

Re: IPv6 prefix assignment problem

Thank you for the answer :).

I have tried to make some restriction. Here is my approach:

class "N-005-BA-OLT-02"
{
match if substring (option dhcp6.interface-id, 0, 15) = "N-005-BA-OLT-02";
}

#06/06/2017 zoznam komplet subnetov nie len pre SK region
#---------------------------------------------------------------------------------------------
subnet6 2a01:c840:0070:0140::/64 {
   prefix6 2A01:C846:140:: 2A01:C846:17F:F000:: /56;
   # N-005-BA-OLT-02
   option dhcp6.aftr-name 61:61:66:74:72:32:2e:61:75:72:6f:2e:6f:72:61:6e:67:65:2e:73:6b ;
   # aaftr2.auro.orange.sk
   option dhcp6.name-servers 2a01:c840:110:c000::10 , 2a01:c840:130:c000::10 ;
   allow members of N-005-BA-OLT-02;
   deny all clients;
}

I was unable to run dhcp sevrer.

Then i checked source code:
/* allow-deny-keyword :== BOOTP
        | BOOTING
      | DYNAMIC_BOOTP
      | UNKNOWN_CLIENTS */

Currect version doesnt support "allow members of ..." :(.

Any idea?

Re: IPv6 prefix assignment problem

The class name in the allow statement should be in double-quotes:
# ------------------ pool6 { allow members of "Microsoft"; range6 2603:xxxx:yyyy:zzzz:4:50f7:: 2603:xxxx:yyyy:zzzz:4:50f7::ff; }# ------------------
This works on dhcp-server-4.3.2-8.fc22.x86_64

Thank you for the answer :).

I have tried to make some restriction. Here is my approach:

class "N-005-BA-OLT-02"
{
match if substring (option dhcp6.interface-id, 0, 15) = "N-005-BA-OLT-02";
}

#06/06/2017 zoznam komplet subnetov nie len pre SK region
#---------------------------------------------------------------------------------------------
subnet6 2a01:c840:0070:0140::/64 {
   prefix6 2A01:C846:140:: 2A01:C846:17F:F000:: /56;
   # N-005-BA-OLT-02
   option dhcp6.aftr-name 61:61:66:74:72:32:2e:61:75:72:6f:2e:6f:72:61:6e:67:65:2e:73:6b ;
   # aaftr2.auro.orange.sk
   option dhcp6.name-servers 2a01:c840:110:c000::10 , 2a01:c840:130:c000::10 ;
   allow members of N-005-BA-OLT-02;
   deny all clients;
}

I was unable to run dhcp sevrer.

Then i checked source code:
/* allow-deny-keyword :== BOOTP
        | BOOTING
      | DYNAMIC_BOOTP
      | UNKNOWN_CLIENTS */

Currect version doesnt support "allow members of ..." :(.

Any idea?

As I see it, you have no restrictions on either subnet so DHCP is
free to allocate from either one.

I am testing following scenarion:

- two relay agent exists (one for subnet1 and second from subnet 2)

- i try to migrate device from subnet2 into subnet1. I suppose that i will get another prefix delegation. But as you can see in the debug messages, it doesnt work.

Could you help me please? Thx
