Hello!
I'm trying to configure PPP with DHCP relay with VRF aware.
The clients are connected with PPP with authentication method of CHAP.
The ASR send the authentication to the ACS the ACS return to the ASR to which VRF and which unnumbered interface to assign the virtual-access interface.
Then the ASR sends a DHCP request to the DHCP server.
I got everything to work except the DHCP part.
Configs:
vrf def A
address-family ipv4
!
interface lo1
vrf forwarding A
ip address 2.2.2.2 255.255.255.255
!
interface Virtual-template 1
ip unnumbered lo0
no ip redirects
no ip proxy-arp
ip tcp adjust-mss 1420
peer ip address forced
peer default ip address dhcp
ppp authentication chap
!
ip address-pool dhcp-proxy-client
ip dhcp-server 1.1.1.1
ip dhcp-server 1.1.1.2
!
I can see the router derive configuration from the virtual-template but with wireshark I don't see it sends any DHCP packets.
Ideas?
