Hi Alexandr,

Not quite, this is the corrected diagram:

         .--->-- rpki.ripe.net ---->--------.
         |                                  |
         |                                  |
         |                                  |
         ^ echo request:                    V echo reply:
         |  172.16.0.91 -> 193.0.6.138      |  193.0.6.138 -> 172.16.0.91
         |                                  |
         | vlan367                          | vlan313
  ,------+-------.                   ,------+-------.
  | gw2          |          vlan209  | gw1          |
  | 172.16.0.91  +-------------------+ 172.16.0.90  |
  |              |                   |              |
  |              +-------------------+              |
  |              |          vlan409  |              |
  `--------------'                   `--------------'

That does fix it!

Would you mind explaining more about this?

Thanks,
