Issues getting PPPOE working between Linux over VMWARE with CSR 1000v

[sanigepalli]

Basically, trying to verify PPPoe support on CSR1000v using Roaring Penguin PPP stack on Linux VM(Oracle VM box)

CSR1000v is configured as BDI and in the same network as VMWare Linux Emulation box. 


PPPoE stack is being run on Linux as a PPP client. CSR 1000v is acting as PPP server. 

The CSR1000v configuration script is attached.

PADI and PADO messages get exchanged. For PADR message, PADS comes back with an error " AC-System -Error: AC Cannot Open PPPoE Session"


The PPPoE exchanges between CSR1000v and Linux VM is also attached.

I like to know what can be done to get a proper exchange and move on to other PPPoE messages for credits etc.

Has any one gotten this working ? Let us know

PPPoE is not supported along with Ethernet features on that device.

Restrictions for Bridge Domain Interfaces
The following are the restrictions pertaining to bridge domain interfaces:

Only 4096 bridge domain interfaces are supported per system.
For a bridge domain interface, the maximum transmission unit (MTU) size can be configured between 1500 and 9216 bytes.
Bridge domain interfaces support only the following features:
– IPv4 Multicast

– QOS marking and policing. Shaping and queuing are not supported

– IPv4 VRF

– IPv6 unicast forwarding

– Dynamic routing such as BGP, OSPF, EIGRP, RIP, ISIS, and STATIC

– Hot Standby Router Protocol (HSRP) from IOS XE 3.8.0 onwards.

– Virtual Router Redundancy Protocol (VRRP) from IOS XE 3.8.0 onwards.

Bridge domain interfaces do not support the following features:
– PPP over Ethernet (PPPoE)

– Bidirectional Forwarding Detection (BFD) protocol

– Netflow

– QoS

– Network-Based Application Recognition (NBAR) or Advanced Video Coding (AVC)

Thanks Dean for a quick response. In such case, Any idea which interface works with PPPoE ?

EVC with dot1q encapuslated PPPoE.
