Hi Jonas,
In that output you have "Remote VLAN id: 42" -What is the local VLAN
ID on your Cisco PE? Do you need to VLAN rewrite here?
Since you using different VLANs at each end, can you build the
pseudowire at a point in the network stack where the VLAN tag has been
popped off already and transport the frames untagged, so they will be
pushed on again at the other end? (Is this is a VC type 4 pseudowire,
check with "show mpls l2transport binding 42", if so, a dummy VLAN
should be pushed on and popped off transparently if all hardware in
use supports it).
I don't know HP but with the Cisco 7600 for example, if it's VLAN 50
then you could add "interface vlan 50; xconnecy X.X.1.89 42 encaps
mpls", if your hardware supports that. Or use mux-uni; "int gix/x.y;
encaps dot1q y; xconnecy X.X.1.89 42 encaps mpls". Then add vice versa
on the HP kit.
What IOS have you tried to upgrade to, 15.2(4)S4a? If this is a VC
type 4 pseudowire and either the HP or Cisco isn't supporting
inserting a dummy VLAN tag, why is this a VC type 4 pseudowire? The
VLAN re-write I guess. Certainly in IOS 15.3 (so probably also in 15.2
but I'm not 100% certain of that) Cisco IOS should be defaulting to VC
type 5 unless the other end negotiates down to VC type 4. VC type 5 in
IOS supports transporting of untagged, tagged and double tagged
frames, I don't think there is any functionality in VC type 5 that
wasn't in older type 4's so I'd try and work out why your devices are
negotiating type 4 and maybe try to fix that, or as above, transport
untagged.
Cheers,
James.

Re: Project Fi and the Great Firewall
With Wi-Fi calling it gets a bit more simplified (no "transit" operators in user plane) and may provide better privacy (only your home country will monitor your calls, lol). The UE establishes IPsec tunnel over the Internet to the home operator and uses it for native VoIP/messaging applications.

Josh, If you want to complain about something useful. Complain that CentOS is still at BIND 9.9.4 rather than BIND 9.9.8. You are missing bug fixes. We ship maintainence releases for a reason. This is like saying. We know there are 360 fixes between 9.9.4 and 9.9.8 and we don't think you are going to need any of them despite other people discovering these bugs.

Re: Advance notice - H-root address change on December 1, 2015
No. CentOS follows RedHat. They backport fixes to older versions rather than put the new version out. It appears that have aversion to new feature and just want to put the fixes onto the older versions. So that 9.9.4 probably has 60% of the changes that the diff of 9.9.4 has to 9.9.8 . This action confuses most. alan

Re: Advance notice - H-root address change on December 1, 2015
This action by red hat is nice from a stability perspective but infuriates many standards derived folks like ISC/BIND and NTP amongst others as a version number means something to them. This dialogue is typically broken from both sides as expectations are different and bug reports get lost between the OS packaging and the supplier packaging. Sometimes this is good other times it can be quite bad. I would prefer to see fewer variants and better bug fixes across the board but the enterprise side often want a specific version number and expect fixes that the upstream maintainers don't want to keep the same version numbering for "that fix" or add a stealth feature and red hat may not want to pick it up... Not saying who is right or wrong but these views sometimes drive the intractable situation where 4.2.6 is shipped for NTP from red hat (as example) but it is EOL from the NTP.org folks. The good news is most people don't need all 13 hints, or more when you consider them dual stacked like all new DNS servers are :-) Either way it's confusing to everyone involved and why I generally track fedora myself.

Red Hat has known for YEARS that we only have the resources to support one stable code branch, and that if they want support for older versions we can offer that at cost. Nobody has ever approached us about support for older releases of NTP. The folks who scream the loudest about our not supporting older releases are the folks who charge their customers money for support. These same companies do nothing to support us. Anybody can see the list of companies that support NTP at: http://nwtime.org/current-members-donors/ The free software companies listed there do not give us any money. >> On Nov 16, 2015, at 7:16 PM, Mark Andrews wrote: >> >> The point of putting out maintainence releases is to fix bugs in >> the existing code not to introduce features.

In NTP's case, we fixed over 1100 things between 4.2.6 and 4.2.8. Skippy (Harlan'e evil twin brother)
