From a0e5c15d4f5eb47ddb26850c6b99b1e110e0c270 Mon Sep 17 00:00:00 2001 From: Florian Klink Date: Sat, 11 Feb 2017 00:47:55 +0100 Subject: networkd: add IPv6ProxyNDPAddress support (#5174) IPv6 Neighbor discovery proxy is the IPv6 equivalent to proxy ARP for IPv4. It is required when ISPs do not unconditional route IPv6 subnets to their designated target, but expect neighbor solicitation messages for every address on a link. A variable IPv6ProxyNDPAddress= is introduced to the [Network] section, each representing a IPv6 neighbour proxy entry in the neighbour table. --- man/systemd.network.xml | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'man') diff --git a/man/systemd.network.xml b/man/systemd.network.xml index 7818dfff81..b807ebf29b 100644 --- a/man/systemd.network.xml +++ b/man/systemd.network.xml @@ -611,6 +611,25 @@ Defaults to unset. + + IPv6ProxyNDPAddress= + An IPv6 address, for which Neighbour Advertisement + messages will be proxied. + Proxy NDP (Neighbor Discovery Protocol) is a technique for IPv6 to + allow routing of addresses to a different destination when peers expect them + to be present on a certain physical link. + In this case a router answers Neighbour Advertisement messages intended for + another machine by offering its own MAC address as destination. + Unlike proxy ARP for IPv4, is not enabled globally, but will only send Neighbour + Advertisement messages for addresses in the IPv6 neighbor proxy table, + which can also be shown by ip -6 neighbour show proxy + This option may be specified more than once. systemd-networkd will control the + per-interface `proxy_ndp` switch for each configured interface, depending on whether + there are entries configured and add these to + the kernels IPv6 neighbor proxy table. + Defaults to unset. + + Bridge= -- cgit v1.2.3-54-g00ecf
