  2. I do not understand how you came up with the subnet masks for the 172.16.0.0 and 172.20.0.0 networks. Could someone please help me out a little bit?

  3. Those are summary routes.

    Add up all the matching consecutive bits of all subnet Network Addresses you want to summarize. That number becomes your mask.

    In the case of 172.16.0.0, 172.16.4.0, 172.16.8.0 & 172.16.12.0

    There are 20 matching consecutive bits so your mask is 255.255.240.0 (8+8+4=20)

    In binary:

    10101100.00010000.0000 | 0000.00000000 (172.16.0.0)
    10101100.00010000.0000 | 0100.00000000 (172.16.4.0)
    10101100.00010000.0000 | 1000.00000000 (172.16.8.0)
    10101100.00010000.0000 | 1100.00000000 (172.16.12.0)

  4. 172.16.0.0 & 172.16.12.20 is mentioned in the topolgy itself.

  5. Your 2 missing routes for HQ are:
    ip route 172.16.0.0 255.255.240.0 s0/0/1
    This points to B2
    ip route 172.20.0.0 255.255.128.0 s0/1/0
    This points to B3

  9. the missing static routes in HQ:
    Para el espacio 192.168.0.0/27 Tenemos:

    ip route 192.168.0.128 255.255.255.224 fa0/0
    ip route 192.168.0.160 255.255.255.224 fa0/1

    Works!
