Subject: PPPOE with DHCP assigned IP address
Hi All
I am having a little problem here.
I have setup a PPPOE client/server relationship and I want to exclude IP's
from being assigned from the DHCP pool.
Now the only caveat here is that the Server ie Virtual-template interface is
sitting in a VRF. I have added the IP Dhcp-excluded command to exclude the
IP's I don't want assigned however it doesn't seem to be working. Here are my
configs
SERVER
ip dhcp excluded-address 10.1.1.3 10.1.1.255
!
ip dhcp pool PPPOE
vrf ABC
network 10.1.1.0 255.255.255.0
interface Virtual-Template1
ip vrf forwarding ABC
ip address 10.1.1.1 255.255.255.0
peer default ip address dhcp-pool PPPOE
ppp ipcp mask 255.255.255.0
CLIENT
ip dhcp pool local
import all
origin ipcp
interface Dialer1
ip address pool local
encapsulation ppp
dialer pool 1
dialer idle-timeout 0
dialer persistent
ppp ipcp mask request
OUTPUT
R1#sh ip dhcp pool
Pool PPPOE :
Utilization mark (high/low) : 100 / 0
Subnet size (first/next) : 0 / 0
VRF name : ABC
Total addresses : 256
Leased addresses : 0
Pending event : none
1 subnet is currently in the pool :
Current index IP address range Leased addresses
10.1.1.9 10.1.1.0 - 10.1.1.255 0
As you can see if I show the pool you can still see that 10.1.1.0 to .255 is
available, however I did exclude from .3 upwards
The only reason I can think that this is happening is that although I have
told the DHCP pool to be in VRF ABC, the IP excluded address's are in the
"global" table not specific to the VRF
Any help here ?
