From 62dd93181aaa1d5a501a9cebcb254f44b8a48af7 Mon Sep 17 00:00:00 2001 From: Ville Nuorvala Date: Fri, 22 Sep 2006 14:43:19 -0700 Subject: [IPV6] NDISC: Set per-entry is_router flag in Proxy NA. We have sent NA with router flag from the node-wide forwarding configuration. This is not appropriate for proxy NA, and it should be set according to each proxy entry's configuration. This is used by Mobile IPv6 home agent to support physical home link in acting as a proxy router for mobile node which is not a router, for example. Based on MIPL2 kernel patch.
