Solving Mikrotik Bgp Multihop not adding correct gateway when using Gre Tunnel

I decided to write down this article because i confronted myself with same issue first because my background expertise is on Linux mainly i didn`t expected that Mikrotik behave like this but afterwards reading on some Mikrotik forums i saw they promise they will resolv it on v7 but i made it possible on v6.29.1 on Mikrotik CCR but i suppose that the software packages are the same on all Mikrotik Routers.

First the infrastructure :

gretunnelbgpmultihopmikrotik

Networking Config

Mikrotik CCR
Internet config
Real IP : 1.1.1.2
Netmask : 255.255.255.0
Gateway : 1.1.1.1
Gre tunnel config :
Ip on gre interface : 10.10.101.2
Netmask : 255.255.255.0
Linux server
Internet config
Real IP : 2.2.2.2
Netmask : 255.255.255.0
Gateway : 2.2.2.1
Gre tunnel config :
Ip on gre interface : 10.10.101.1
Netmask : 255.255.255.0

The tunnel was put it in state enable on Mikrotik CCR with basic config with specific routes to function , same on Linux Server.

Purism crowd-funding Librem 13 Linux laptop, preparing second-generation Libre 15

Purism, the open-source laptop maker behind the Librem 15, is at it again, heading back to the crowd-funding well for an addition to its lineup. As it did with its original notebook, the company is seeking funding via Crowd Supply to create the Librem 13, a smaller, slighter cheaper portable that runs its PureOS and emphasizes user privacy.

Specs for the Librem 13, which will start at $1,649, include a 13.3-inch 1,920×1,080 screen, Intel Core i5-5200U processor, 4GB of RAM, and 500GB hard drive. You can max out RAM at 16GB and storage space at either a 1TB hard drive or SSD. Perhaps more important for backers, it can be configured with optional hardware “kill switches” that disable the Librem’s built-in Wi-Fi and webcam and microphone to prevent potential snooping from online predators.

That’s just one of the security features that Purism emphasizes. Its PureOS is a Linux version that does not ship with a binary “blob” in its kernel. It also adds privacy-centric tools like Privacy Badger and HTTPS-Everywhere. One thing Purism hasn’t been able to overcome yet is Intel’s insistence on including the FSP binary in its BIOS, which Purism has been attempting to get removed for its laptops.

In addition to the Librem 13, Purism is preparing a second version of the Librem 15, as the first generation has sold out. In addition to having a larger screen size than the Librem 13, the 15-inch model features a more powerful processor (Intel Core i7-5557U) and more expansion capability (up to 32GB of RAM, an open second drive bay) owing to its bigger footprint. You’ll also pay $200 more for the base Librem 15 when it ships starting next month.

Currently, Purism is only at about 10 percent of its funding goal for the Librem 13, but there are still 40-odd days left in its campaign. The company promises a September shipping date for the first Librem 13 laptops if its funding goal is met. If the Librem 13 is successfully funded, Purism says a Librem tablet would be its next product, with a Librem smartphone potentially developed after that.
