IPv6 routes expire on Debian (lenny) vm

view story
linux-howto

http://serverfault.com – I have a xen domU that keeps forgetting the routes learned after interface startup; for a while everything is ok but eventually the two default routes (a couple link-local addresses of the upstream routers) expire and the machine drops off IPv6 based networks. I'm puzzled as to what could the problem be; obviously the router is answering the first discovery, but why is is failing to refresh or re-discover? Edoardo ()

Static routes are forgotten once the network service is restarted. However, IPv4 static routes can be made persistent by adding them to /etc/sysconfig/static_routes.

IPv6 static routes 28 weeks 3 days ago

I am looking to configure a few hosts with IPv6 on my network. The router (running CentOS 5) is configured with an Hurricane Electric (HE) tunnel which works fine on that host.

However, I would like to statically add a few additional hosts on the same LAN to have IPv6 through this tunnel.

Hi,

I am configuring ipv6 static route by using netlink socket. Its configuring in linux and displayed when I am using netstat command. But static routes are not displaying by using "ip -6 route" command. I am using fedora 14-2.6.35.

I have updated iproute2-2.6.37, even static routes are not displaying.

I noticed in my routes output in RHEL6 (and most 2.6.x series Linux), for every interface I see the creation of the following route in my kernel routing table:

169.254.0.0 0.0.0.0 255.255.0.0 U 1018 0 0 bond0 169.254.0.0 0.0.0.0 255.255.0.0 U 1019 0 0 bond1 169.254.0.0 0.0.0.0 255.255.0.0 U 1020 0 0 bond2

About Kvnpc and IP Routes 3 years 23 weeks ago

Hi Everybody.

I'm working with a VPN network using Kvpnc, and i can connect successfully to my target network and reach all the machines there, but i have a problem.

When i connect to the VPN i lost my general Internet and local network access.

The VPN don't allow the clients to reach a web page, but i have normal Internet access here in my house.

RFC 2462 specifies:

5.5.2. Absence of Router Advertisements

If a link has no routers, a host MUST attempt to use stateful autoconfiguration to obtain addresses and other configuration information. An implementation MAY provide a way to disable the invocation of stateful autoconfiguration in this case, but the default SHOULD be enabled.

I would like to be able to have IPSec / L2TP clients that connect without setting a default route to the tunnel to be able to receive the internal routes of the network they are connecting to.

Example:

I have an endpoint with accessible via 1.1.1.1 which provides access to 172.16.0.0/16, but no other network.
