The wife and kids are a sleep which means I have found some time to play with
this a little :) however not knowing exactly what I can and can't do here is
the what I have come up with. Also for clarification purposes my serial
interfaces are s2/0
With your default configuration I was pulling an IP of 172.16.0.1
RB(config-if)#do sh ip int br | ex un
Interface IP-Address OK? Method Status
Protocol
FastEthernet0/1 10.0.0.250 YES manual up up
Serial2/0 172.16.0.1 YES IPCP up
up
First thing I notice is that we are excluding the entire range for
172.16.18.0/24, I chose to modify this as follows
no ip dhcp excluded-address 172.16.18.1 172.16.18.254
ip dhcp excluded-address 172.16.18.252 172.16.18.253
Most of what we want is in pool 0 however the pool for this range is 1 so I
have added in all of the info from pool 0 to 1 (with the exception of the
network which already exists) also the default router is on an entirely
different subnet so that also has changed
ip dhcp pool 1
no default-router 10.0.0.1
domain-name packetsanalyzed.com
dns-server 172.16.1.250 172.16.2.251
netbios-name-server 172.16.1.18
default-router 172.16.18.252 172.16.18.253
netbios-node-type p-node
lease 30
One more thing on RA will be to modify the s2/0, otherwise our default route
will be pointing to the wrong IP
interface Serial2/0
no ip address 172.16.18.252 255.255.255.0 secondary
no ip address 172.16.18.253 255.255.255.0
ip address 172.16.18.252 255.255.255.0
ip address 172.16.18.253 255.255.255.0 secondary
no peer default ip address dhcp-pool 0
peer default ip address dhcp-pool 1
Assuming no ip route commands we can set the default route via IPCP
RB
int s2/0
ppp ipcp route default
So now let's test this
RA
no ip dhcp excluded-address 172.16.18.1 172.16.18.254
ip dhcp excluded-address 172.16.18.252 172.16.18.253
ip dhcp pool 1
no default-router 10.0.0.1
domain-name packetsanalyzed.com
dns-server 172.16.1.250 172.16.2.251
netbios-name-server 172.16.1.18
default-router 172.16.18.252 172.16.18.253
netbios-node-type p-node
lease 30
interface Serial2/0
no ip address 172.16.18.252 255.255.255.0 secondary
no ip address 172.16.18.253 255.255.255.0
ip address 172.16.18.252 255.255.255.0
ip address 172.16.18.253 255.255.255.0 secondary
no peer default ip address dhcp-pool 0
peer default ip address dhcp-pool 1
RB
Int s2/0
ppp ipcp route default
RB(config-if)#do sh ip int br | ex un
Interface IP-Address OK? Method Status
Protocol
FastEthernet0/1 10.0.0.250 YES manual up up
Serial2/0 172.16.18.1 YES IPCP up
up
RB(config-if)#do sh ip route
Gateway of last resort is 172.16.18.252 to network 0.0.0.0
172.16.0.0/16 is variably subnetted, 3 subnets, 2 masks
C 172.16.18.252/32 is directly connected, Serial2/0
C 172.16.18.15/32 is directly connected, Serial2/0
S 172.16.0.0/16 [1/0] via 172.16.18.252
10.0.0.0/24 is subnetted, 1 subnets
C 10.0.0.0 is directly connected, FastEthernet0/1
S* 0.0.0.0/0 [1/0] via 172.16.18.252
So I don't know if this satisfies the requirements or breaks the rules??
Happy labbing!

Since the first one seem to create some good dialog I thought I would try it
again
RB should have a default route to serial 1/0 (172.16.18.252) on RA. Domain
name, DNS, netbios, netbios type, and lease is required. Lab it up if required.
The configuration can be found here
