BGP, Part I
|

===========
|
||||
|
||||
In the previous tutorial, we discovered how to let [OSPF](/ospf-intro/README.md) dynamically configure routing inside a network. This tutorial provides an introduction to another routing protocol, which is BGP, the Border Gateway Protocol. As the name implies, this protocol acts on the border of a network. Where OSPF is well suited to keep track of all tiny details of what's happening in our internal network, BGP will be talking to the outside world to interconnect our network with other networks, managed by someone else.

|

* A complete network under control of somebody has an AS ([Autonomous System](https://tools.ietf.org/html/rfc1930)) number. By specifying the AS number when configuring BGP connections, we let it know if the neighbour is in our own network (our AS), or in an external network (another AS).
|
||||
* If neighbouring routers between different networks are directly connected, they often interconnect using a minimal sized network range. For IPv4, this is usually a `/30` and for IPv6 a `/120` or a `/126` prefix, containing only the two routers. In the example above, the small network ranges are taken from the network of `AS64080`.
|
||||
* The routes that are published to another network are as aggregated as possible, to minimize the amount of them. While the internal routing table in for example AS64080 might contain dozens of prefixes, for each little vlan, and probably a number of single host routes (IPv4 `/32` and IPv6 `/128`), they're advertised to the outside as just three routes in total.

It's starting to look serious now!
|
||||
### Setting up the containers and networks
|
||||
|
||||
Hopsa, clone some containers, copy paste configuration
|
||||
* already provide bird config with ospf for internal network
|
||||
It's starting to look serious now! Thankfully, most of the configuration is provided already, so we can quickly set up this whole network using our LXC environment. Just like in the previous tutorial, the birdbase container can be cloned, after which the lxc network information and configuration inside the containers can be copied into them.
|
||||
|
||||
1. Clone this git repository somewhere to be able to use some files from the bgp-intro/lxc/ directory inside.
|
||||
2. lxc-clone the birdbase container several times:
|
||||
|
||||
lxc-clone -s birdbase R0
|
||||
lxc-clone -s birdbase R1
|
||||
lxc-clone -s birdbase R3
|
||||
lxc-clone -s birdbase R10
|
||||
lxc-clone -s birdbase R11
|
||||
lxc-clone -s birdbase R12
|
||||
lxc-clone -s birdbase H6
|
||||
lxc-clone -s birdbase H7
|
||||
lxc-clone -s birdbase H19
|
||||
lxc-clone -s birdbase H34
|
||||
|
||||
3. Set up the network interfaces in the lxc configuration. This can be done by removing all network related configuration that remains from the cloned birdbase container, and then appending all needed interface configuration by running the fixnetwork.sh script that can be found in `ospf-intro/lxc/` in this git repository. Of course, have a look at the contents of the script first, before executing it. Since this example is only using IPv4 and single IP addresses on the interfaces, I simply added them to the lxc configuration instead of the network/interfaces file inside the container.
|
||||
|
||||
. ./fixnetwork.sh
|
||||
|
||||
4. Copy extra configuration into the containers. The bgp-intro/lxc/ directory inside this git repository contains a little file hierarchy that can just be copied over the configuration of the containers. For each router, it's a network/interfaces configuration file which adds an IP address that corresponds with the Router ID to the loopback interface, and a simple BIRD configuration file that serves as a starting point for our next steps.
|
||||
|
||||
5. Start all containers
|
||||
|
||||
lxc-start -d -n R0
|
||||
lxc-start -d -n R1
|
||||
lxc-start -d -n R3
|
||||
lxc-start -d -n R10
|
||||
lxc-start -d -n R11
|
||||
lxc-start -d -n R12
|
||||
lxc-start -d -n H6
|
||||
lxc-start -d -n H7
|
||||
lxc-start -d -n H19
|
||||
lxc-start -d -n H34
|
||||
|
||||
6. Verify connectivity and look around a bit. Here's an example for R1:
|
||||
|
||||
lxc-attach -n R1
|
||||
|
||||

As you can see, OSPF is running for IPv4 and IPv6, and has discovered the complete internal network of AS64080.
|
||||
|
||||
Now make sure you can do the following, or answer the following questions:
|
||||
* From H6, `traceroute -n` and `traceroute6 -n` to a few destinations in AS64080 to get acquainted with the network topology.
|
||||
* Look at the BIRD logging. A fun way to follow the logging is to do `tail -F R*/rootfs/var/log/bird/*.log` from outside the containers, and then start all of them.
|
||||
* Find out why `10.40.217.18` or `2001:db8:40:d910::2` on `R10` cannot be pinged from `R1`, while the route to `10.40.217.16/30` and `2001:db8:40:d910::/120` are actually present in the routing table of `R1` and `R3`.
