19Frequently Asked Questions:
20===========================
21
22Setting up radvd is very simple, so the most frequently asked
23questions have been about what radvd _doesn't_ do...
24
25 1. How do I set up the router running radvd to automatically
26 configure an address from the prefix advertised in Route
27 Advertisements from upstream?
28
29 -- You don't. By the specification, routers ignore RAs.
30 You'll probably need to use manual configuration. But you
31 can't use the same prefix on two links in any case unless you
32 use something like proxy-ND (draft-ietf-ipv6-ndproxy-04.txt).
33 You may need to re-think your topology; prefix delegation
34 (e.g., manually or with RFC3633) may help.
35
36 2. How do I set up the router running radvd to automatically
37 configure the interfaces to use an EUI64-based address?
38
39 -- You don't. The design philosophy of radvd is that it's
40 not the _router's_ configuration tool, but a route advertising
41 daemon. You'll need to set up all the addresses, routes, etc.
42 yourself. These tasks are something that system initscripts
43 could possibly do instead.
44
45 3. I have a dynamic /48 prefix. How do I set up radvd to:
46 a) set up interface addresses and routes on downstream
47 interfaces, and
48 b) advertise /64 prefixes from the /48 on downstream interfaces?
49
50 -- For a), this isn't supported. For b), radvd includes special
51 support for 6to4 upstream interface but assumes that the interface
52 addresses/routes are set up manually. This should probably
53 be done in the initscripts or manually. (Though if someone were
54 to send a patch for b), it might be incorporated.)
55
56 4. How do I set up radvd to do either unicast or multicast routing?
57
58 -- You don't. Radvd is not a routing or forwarding daemon.
59 You need to set any appropriate routing/forwarding first,
60 and then radvd to only advertise the prefixes to hosts as
61 appropriate.
