  1. Hi Rene,
    Interesting scenarios and explained by you clearly.

    Thanks,

  2. I’m confused about the 172.16.1.0 subnet.
    I guess the address 172.16.1.1 does somehow configure automatically in the HOST.

    Two questions :

    1 - Why the static rule is simply not something like ip route 172.16.1.0 255.255.255.0 192.168.12.1 ?

    2 - How come a private (inside) network (172.16.1.0) be advertised for outside of the NAT ?

  3. Hello Maodo

    The 172.16.1.0 subnet is a range of addresses that are given to us by the ISP that will be used to translate the INSIDE addresses to the OUTSIDE. In other words, when the Host communicates to the outside world, the 192.168.12.1 address will be translated to 172.16.1.X when it traverses the NAT router. So from the NAT router outwards, all communication occurs with the IP address 172.16.1.X. Note that this subnet essentially “exists” on the F1/0 interface of the NAT router. In a sense, it coexists with the 192.168.23.2 IP address on that interface

  4. Working on the ISP side at Level 3 Communication and Zayo I always found it interesting because on the academic side they always say BGP is not really needed unless you need to do load balancing across multiple ISP.

    However, when your actual out there in the real world that doe not seem to be how the majority do it. Basically I would say the majority use BGP even for single connections. Laz Hypothesis sounds as reasonable as any that its easier for the ISP so they just go with BGP. I never really asked that question and most of the guys and girls around me
