  * Check that you can reach every external network from every router in all of the three networks. You can use the script `bgp-contd/lxc/check_connectivity.sh` to check that every router can ping any other router.
- * Try disabling some of the links between routers by using the `disable`/`enable` commands on the bird command line, and check if you still can reach all parts of the network.
+ * Try disabling the link between `R0` and `R11`, by using the `disable`/`enable` commands on the bird command line, from either side. Check if you still can reach all parts of the network. Do the same for the link between `R1` and `R10`. If this succeeds your iBGP configuration is correct.
  * Change `import` and `export` filters in the `protocol bgp ebgp_r*` sections in `bird6.conf` so that you end up with a situation where all traffic is forced into an asymmetric traffic pattern in which traffic from `AS65000` to `AS65010` has to leave via `R1` to `R10`, and traffic back flows over `R11` to `R0`. Verify the changes seen in bird `show route all` output when you change filters.
