Hi Andres,
I hope it is due to lease time issue. Even during my practice i have faced
same issue.
Wait for the default 1 hr and check the same.
Regards,
Vignesh

What IOS releases are you using ?
It worked for me when using 12.3(8)T11 on both the client and server. It was
not necessary to specify the vrf under the dhcp pool.
But it didn't work when the client and server are running 12.2(8)T (with or
without vrf under the dhcp pool).
For some reason, the client refuses the assigned address:

01:06:51: DHCPD: assigned IP address 12.12.12.1 to client
0063.6973.636f.2d63.6330.302e.3061.3938.2e30.3030.302d.4469.31.

01:06:51: DHCPD: client rejected 12.12.12.1, sent 12.12.12.1.
01:06:51: DHCPD: returned 12.12.12.1 to address pool PPPoE.

I don't see the feature "VRF Aware DHCP Server" documented anywhere. Do you
have any documentation about this ?

Subject: PPPOE and DHCP POOL issue
Hi group,
I have configured pppoe between r1 and r2 and have configured dhcp poll with
exclude so that r1 single receives the 10.1.1.1
address. The mentioned configuration works fine, but when I apply the
command 'ipvrf forwarding XX'
under the virtual-template the int dialer does not receive the Ip address.
Then I add within pool the command vrf XX. After making this the interface
dialer receives IP but not exclude the mentioned
directions in the ip dhcp excluded-address.
R1 config:
interface fastethernet 0/1
no ip address
pppoe enable
pppoe-client dial-pool-number 1
!
interface dialer 1
ip address dhcp
encapsulation ppp
no peer neighbor-route
ppp chap hostname cisco
ppp chap password 0 cisco
dialer pool 1
r2 config:
username cisco password 0 cisco
aaa authentication ppp PPP local
!
vpdn enable
!
vpdn-group 1
accept-dialin
protocol pppoe
virtual-template 1
!
interface fastethernet 0/1
no ip address
pppoe enable
!
interface virtual-template 1
ip address 10.1.1.8 255.255.255.0
no peer neighbor-route
ppp authentication chap PPP
!
ip dhcp pool test
network 10.1.1.0 255.255.255.0
vrf XX
!
ip dhcp excluded-address 10.1.1.2 10.1.1.254
Please, let me know the opinion about the issue.
Thanks.
