NAME

6       ndppd.conf - configuration file for ndppd
7

DESCRIPTION

9       The syntax is as follows:
10
11       proxy eth0 {
12          rule 1234:5678::/96 {
13          }
14       }
15
16       The  configuration  file  must  contain one or more proxy sections, and
17       each of these section must contain one or more rule sections.
18
19       The ndppd daemon listens on the interface specified as an  argument  to
20       the  proxy  section.  Once  a Neighbor Solicitation message arrives, it
21       will try to match the target address against the address  specified  as
22       the argument of the rule section.
23

OPTIONS

25       proxy <interface>
26              Adds a proxy and binds it to the specified interface.  See below
27              for information about proxy options.
28

PROXY OPTIONS

30       rule <address>
31              Adds a rule with the specified address to the proxy. It may be a
32              an  IP  such as 1234::1 or a subnet such as 1111::/96. See below
33              for information about rule options.
34
35       ttl <value>
36              Controls how long ndppd will cache an entry.  This  is  in  mil‐
37              liseconds, and the default value is 30000 (30 seconds).
38
39       timeout <value>
40              Controls  how  long ndppd will wait for a Neighbor Advertisement
41              message after forwarding a Neighbor Solicitation message accord‐
42              ing  to the rule. This is in milliseconds, and the default value
43              is 500 (.5 second).
44
45       router <yes|no>
46              Controls if ndppd should send the router bit when sending Neigh‐
47              bor Advertisement messages. The default value here is yes.
48

RULE OPTIONS

50       Specify a method here. See below.
51

METHOD

53       One of the following options must be specified in the rule section. All
54       of these are mutually exclusive options, and cannot be combined.
55
56       iface <interface>
57              Specify which interface the Neighbor Solicitation  message  will
58              be sent out through.
59
60       auto   (NEW)  If  this option is specified ndppd will attempt to detect
61              which interface to use in order to forward Neighbor Solicitation
62              Messages, by reading the routing table /proc/net/ipv6_route.
63
64       static (NEW) This option tells ndppd that it should immediately respond
65              to a Neighbor Solicitation Message without querying an  internal
66              interface.   Note that it's recommended that you use this option
67              sparingly, and with as high prefix length as possible.  This  is
68              to  make  sure  upstream  routers are not polluted with spurious
69              neighbor entries.
70
71              If no rule option has been specified, it will default to  static
72              in  order to be compatible with 0.2.1.  This will, however, pro‐
73              duce a warning, and most likely not work in future  versions  of
74              ndppd.
