[Bug 235258] Re: routes ignored advertised in ipv6 router advertisement packets

 

AZ, this bug was reported a while ago and there hasn't been any activity
in it recently. We were wondering if this is still an issue? If so,
could you please test for this with the latest development release of
Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-
live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  routes ignored advertised in ipv6 router advertisement packets

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm using ipv6 on a tun device. My router (a debian system) sends out router advertisements using radvd which are received by my ubuntu machine and used for address generation.
  Although the ra's include route information, this is ignored. 
  The interface uses the fec1::/64 prefix and routing is advertised for fec0::/64.
  I cannot add this route to /etc/network/interfaces, as it comes up after vpn is started.

  radvdump:

  interface tap0
  {
  	AdvSendAdvert on;

  	prefix fec1::/64
  	{
  	}; # End of prefix definition

  
  	route fec0::/64
  	{
  		AdvRouteLifetime 30;
  	}; # End of route definition

  
  	RDNSS fec1::254
  	{
  		AdvRDNSSLifetime 10;
  	}; # End of RDNSS definition

  }; # End of interface definition
