Subject: bookends.m4: Configure IPv6 router advertisement stuff.
X-Git-Url: https://git.distorted.org.uk/~mdw/firewall/commitdiff_plain/64de9249b91190ffe73b78f1aa6c74d1c88b3afc

bookends.m4: Configure IPv6 router advertisement stuff.

Servers are expected to listen in on the routing protocols, so even
though they aren't actually routers, they still shouldn't listen to
the advertisements.
