Hi group,
I have a problem assigning bb2 (router acting as dhcp client) the ip address
150.50.4.12 which has been manually mapped to bb2 mac address on the dhcp
server (r7).
The r8 is the dhcp relay agent residing between r7 and bb2.
r7 and r8 have the serial connection between them.
r8 and bb2 have ethernet connection between them.
I have included the configuration for all routers below. The problem is that
the dhcp server (r7) will assign the client any ip address other than
150.50.4.12, which is not the desired result. The desired result is that bb2
should be assigned the ip address 150.50.4.12 by the dhcp server.
Can someone see what the problem is?
