6 ndppd.conf - configuration file for ndppd
7
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
25 proxy <interface>
26 Adds a proxy and binds it to the specified interface. See below
27 for information about proxy options.
28
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
50 Specify a method here. See below.
51
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.
