Hello Ben. Question for you on your notes. Those are excellent by the way! My question is this. In your notes for DMVPN/BGP you mention having the hubs defined as route reflectors. Is this the preferred way versus having the core switch defined as the route reflector or should the core switch be a RR-client? Thanks.

Hi Ben, around 2:45 you mention that you are not going to change the MTU settings on the tunnel interface you're using BGP. Can you elaborate on that? I thought you had to set it to 1400 because of the extra headers in IPSec etc.

Hi, I think what I meant to say there, was that I didn't need the multicast option because I'm using BGP. As to why I didn't add the MTU, I'm not sure.... probably because I didn't think it was needed in this example or laziness :)

+Ben Pin ah. That makes sense, thanks for the reply :)
