Re: [vpp-dev] assertion in gpe testing

2017-12-10 Thread Florin Coras
In that case, before configuring a gpe forwarding entry you need a route for 
your tunnel’s destination, i.e., the remote locator you’ve configured in the 
“locs” list. Only once you have such a route add the lisp forwarding entry. 

Hope this helps,
Florin

Re: [vpp-dev] assertion in gpe testing

Hi Florin,

After starting VPP, I just configured two commands, first is "lisp enable on", 
another command(not congfig in vpp CLI) is to directly pass parameter 
parameters to vl_api_gpe_add_del_fwd_entry_t_handler. This problem exists every 
time in the 18.01 version of VPP

[vpp-dev] assertion in gpe testing

2017-12-10 Thread ??????

Hi guys,

There is an assertion when I was configuring the GPE service, and I didn't find 
a solution. Can you help me see the reasons for it?
