Certain clients (such as Windows clients) can lose router information even if previously advertised via router advertisement. This occurs because neighbor discovery messages are handled by proxy even in transparent mode for VLAN groups.
Some clients might lose router information and cannot send traffic.
Conditions under which this manifests are inconsistent, but it appears to affect Windows clients in various scenarios. For example, when host on one VLAN sends a neighbor advertisement with the router bit set, the proxy code does not preserve it in the proxied response.
avoid stateless auto-configuration or do not auto-configure cross vlan boundaries.
Router information is now preserved correctly by proxy ARP/NDP code for VLAN groups.
