Hi List, I'm having a very strange issue with some very basic PPPoE config. Vol 3 Lab Task 2.4
When I initially went through the task, I had configured everything just as the DSG had configured it. And the pppoe session comes up without any issues. However, it says to NOT assign the IP via IPCP, so we simply use DHCP. So I configure my DHCP server and exclude every IP except the one that's supposed to go to R7, but this is what the debugs show when the discover goes out from R7 to R6 .... R6 - DHCP Server - *Nov 14 03:00:22.811: DHCPD: IP address change on interface Virtual-Access1.1 *Nov 14 03:00:22.811: DHCPD: IP address change on interface Virtual-Access1.1 *Nov 14 03:00:22.819: DHCPD: allocate request for client cisco-141.41.67.6-Virtual-Access1.1 on Virtual-Access1.1. *Nov 14 03:00:22.819: DHCPD: Pool pppoe specified. *Nov 14 03:00:22.819: DHCPD: Interface Virtual-Access1.1 is not associated with any VRF. *Nov 14 03:00:22.819: DHCPD: found pool pppoe for client cisco-141.41.67.6-Virtual-Access1.1. *Nov 14 03:00:22.819: DHCPD: Allocate an address without class information (141.41.67.0) *Nov 14 03:00:24.819: DHCPD: Adding binding to radix tree (141.41.67.7) *Nov 14 03:00:24.819: DHCPD: Adding binding to hash tree *Nov 14 03:00:24.819: DHCPD: assigned IP address 141.41.67.7 to client 6369.7363.6f2d.3134.312e.3431.2e36.372e.362d.5669.7274.7561.6c2d.4163.6365.7373.312e.31.

The dialer1 interface never receives the IP. A "sho ip int brief" on R7 doesn't have any interface with the IP, so what is grabbing the IP before the virtual-access bound to dialer1 gets a chance?? I know it's whatever that ridiculously long client id is ... but what is that and where did it come from?? -- max _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
