Group, did anybody make this work? Somehow R4 can not get dhcp assignment
from R1.
R1 thinks it has assigned though. So, I did make R5 server which is directly
connected to R4, and it works.
Plus, R1 sees a very weird MAC address for the IP assigned.
I did adjust NTP as well, make sure lease is infinite as well.

36f.2d31.3339.2e35.2e34.352e.352d.5365.7269.616c.302f.31.

Let me know if you made it work.

R4-S0/1---PPP--S0/1-R5-S0/0---Frame---S0/0-R1

They have network connectivity. If I put the R4's IP manually, they can all
ping each other.
