[vpp-dev] problem in pppoe testing

[xyxue]

Hi guys,

I'm testing the pppoe . I followed the guide of docs.fd.io . But can't confige 
success. Is there any configuration manual ?
The configuration of mine is shown below:

DBGvpp# create pppoe cp cp-if-index 1 
DBGvpp# show interface 
              Name               Idx       State          Counter          
Count     
host-eth1                         1        down      
local0                            0        down      

DBGvpp# create pppoe session client-ip 10.0.3.1 session-id 13 client-mac 
00:01:02:03:04:05 
create pppoe session: vnet_pppoe_add_del_session returned -2
DBGvpp# show pppoe fib 
no pppoe fib entries
DBGvpp# 

Is there any problem in my configuration?

Thanks,
