In RFC7774 MPL Parameters
One network may have multiple MPL Domains with different
configurations. To configure more than one MPL Domain via DHCP,
there may be more than one MPL Parameter Configuration Option given
to DHCP clients by a DHCP server.
I have tried to configure multiple entries in the dhcpd6.conf but only the
last entry using option code 104 is output in the packet.
# MPL Default Parameters Option 104
option dhcp6.mpl-default-parameters code 104 = {
unsigned integer 8, # flags, 0x80 - proactive
unsigned integer 8, # tunit
unsigned integer 16, # se_lifetime
unsigned integer 8, # dm_k
unsigned integer 16, # dm_imin
unsigned integer 8, # dm_imax
unsigned integer 16, # dm_t_exp
unsigned integer 8, # c_k
unsigned integer 16, # c_imin
unsigned integer 8, # c_imax
unsigned integer 16 # c_t_exp
};
# MPL Domain Parameters Option 104
option dhcp6.mpl-domain-parameters code 104 = {
unsigned integer 8, # flags, 0x80 - proactive
unsigned integer 8, # tunit
unsigned integer 16, # se_lifetime
unsigned integer 8, # dm_k
unsigned integer 16, # dm_imin
unsigned integer 8, # dm_imax
unsigned integer 16, # dm_t_exp
unsigned integer 8, # c_k
unsigned integer 16, # c_imin
unsigned integer 8, # c_imax
unsigned integer 16, # c_t_exp
ip6-address # MPL Domain
};
option dhcp6.mpl-domain-parameters 0x80 100 18000 4 5 16 3 4 20
16 2 ff03::153;
option dhcp6.mpl-domain-parameters 0x80 100 18000 2 1200 4 15 3 1800 4
20 ff03::154;
option dhcp6.mpl-default-parameters 0x80 100 18000 1 1 3 3 1 1 9
10;
I have also tried to configure this as a vendor-encapsulated-options but it
does not appear in the DHCPv6 packet at all.
option vendor-encapsulated-options
00:68:00:10:
80:64:46:50:01:00:01:03:00:03:01:00:01:09:00:0a:
00:68:00:20:
80:64:46:50:04:00:05:10:00:03:04:00:14:10:00:02:
ff:03:00:00:00:00:00:00:00:00:00:00:00:00:01:53:
00:68:00:20:
80:64:46:50:02:04:b0:04:00:0f:03:07:08:04:00:14:
ff:03:00:00:00:00:00:00:00:00:00:00:00:00:01:54;
I am currently running version 4.3.3 but could find no release notes that
indicate support for multiple options with the same code was added or
changed.
Any ideas on how to enable this configuration?
Thanks,
James
