ppp and DHCP-relay

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?

Hi

Did you ever find a solution to this issue

Thank you

Yes,

Didn't had a route from the assigned VRF to the DHCP server.
