Hello,
In this lab the solutions guide has us configure next-hop-self on R1 and I
am not sure why. R1 is not at the edge of this network and AS200 has full IP
connectivity within itself. Withought configuring next-hop-self on R1 I
appear to have full BGP sonnectivity. Is this a typo in the solutions guide
or am I missing something ?
Thanks,
Mike F.
