  2. Hello,

    Should router do icmp redirection to his neighbors when they are in one subnet? This feature of IP protocol doesn’t work in this case, does it?
    I see that you disable icmp redirects by issuing “no ip redirects” command on Tunnel interface.

  3. Hi Renee!
    Great lesson as always

    I was just wondering what about the “ip nhrp server-only” what is the purpose of the command??

  4. Dan,
    That command would be useful only in an environment where you want to force spoke to spoke traffic to flow through the hub–for example in an WAN environment where there is NOT a full mesh between the spokes. In this type of environment it is not possible to have direct spoke to spoke traffic, so you would not want the spokes to ask for NHRP shortcut information (since they couldn’t use it anyway).

    The server-only option prevents the NHRP router from sending out resolution requests as part of the attempt to establish a shortcut.

  5. That make sense now
    Thanks for the good explanation Andrew!
