All, I'm currently evaluating the ASR9001 as a BNG for IPoE traffic (Double VLAN tagged traffic, doing DHCP) - but I'm having difficulties getting the DHCP proxy bit working. Has anyone done this before, or can anyone help point me in the direction of why my config isn't working?
I've been working through the example at https://supportforums.cisco.com/docs/DOC-19702 and have come up with the following config: ------ 8< -------- 8< --------- dhcp ipv4 profile IP_DEFAULT proxy helper-address vrf default 192.168.130.20 giaddr 100.64.248.129 relay information check relay information option relay information policy keep relay information option allow-untrusted ! interface Bundle-Ether1.3121 proxy profile IP_DEFAULT ! interface Bundle-Ether1.3121 ipv4 address 100.64.248.129 255.255.255.192 service-policy type control subscriber IP_PM ipsubscriber ipv4 l2-connected initiator dhcp ! encapsulation ambiguous dot1q 3121 second-dot1q any ! interface TenGigE0/0/2/1 bundle id 1 mode on ! dynamic-template type ipsubscriber IPSUB_TPL ! ! class-map type control subscriber match-any DHCP match protocol dhcpv4 end-class-map ! policy-map type control subscriber IP_PM event session-start match-first class type control subscriber DHCP do-until-failure 5 activate dynamic-template IPSUB_TPL ! ! end-policy-map ! end ------ 8< -------- 8< --------- Now, if I do "debug dhcp ipv4", I can see my DHCP requests coming in, and it starts to process them, but the requests are never forwarded to my DHCP server. If I do "show dhcp ipv4 proxy binding detail", it sees the client ok, but doesn't show the server address: ------ 8< -------- 8< --------- RP/0/RSP0/CPU0:test-asr9k.lab.cc#show dhcp ipv4 proxy binding detail Thu Jun 6 22:08:00.070 UTC MAC Address: 100d.7f4d.1cda VRF: default Server VRF: - IP Address: 0.0.0.0 Giaddr from client: 0.0.0.0 Giaddr to server: 0.0.0.0 Server IP Address: 0.0.0.0 Server IP Address to client: 0.0.0.0 ReceivedCircuit ID: Xxx-21 eth 3/1/2/1/1:102 InsertedCircuit ID: Xxx-21 eth 3/1/2/1/1:102 ReceivedRemote ID: SimonsHouse InsertedRemote ID: SimonsHouse ReceivedVSISO: - InsertedVSISO: - Auth. on received relay info:FALSE Profile: IP_DEFAULT State: INIT Proxy lease: 60 secs (00:01:00) Proxy lease remaining: 22 secs (00:00:22) Client ID: 0x01-0x10-0x0D-0x7F-0x4D-0x1C-0xDA Access Interface: Bundle-Ether1.3121 Access VRF: default VLAN Id: outer 3121, inner 102 Subscriber Label: 0x0 * * Next renew request from this client will be NAK'd in order to recreate subscriber session ------ 8< -------- 8< --------- Any ideas why it might not be forwarding on the DHCP requests?
