Hi,
Here it goes
1. 'show ip dhcp pool' out put NEED not show you the excluded ip addresses
(this doesnt matter you have a vrf or not)
Try this on a normal router -
2.You dont have to worry if exculded address is part of vrf or not.
3. Even you dont have to bind the dhcp pool to the vrf, if you are binding
to the virtual template using the command *'peer default ip address
dhcp-pool* *XXXX'-* But binding with the vrf is a best pratice
4. Your configuration is correct, and your PPPOE will not take any ip from
the exculded list
5. With the same configuration, try changing the excluded address range to
*'ip dhcp excluded-address 10.1.1.1 10.1.1.20'*
**
*6.* Issue 'clear vpdn tunnel pppe, on Cleint
**
*7.* Shut and Unshut your Dialer Interface on the Client
8. Check the new IP leased by the cleint .
9.Side note : Make your configuration simple on the Client -
int Dialer 1
ip address DHCP ( is enough)
Hope this helps
Regds
