Hi Lou, I am looking deeper at EVPN implementation, with patch "VNC; L3 & L2 VPN application support". To get more familiar with this, I tried to mount a setup based on Mesh NVA configuration example that can be found on doc/vnc.texi file, and make a BGP exchange between the two BGP speakers. At establishment, I got this error message : unsupported AFI/SAFI 0/0.
So , I am wondering if there is a setup issue, or a side effect due to some mis-configurations ? I only took 2 BGP Speakers instead of 3 ( I don't think it should affect the behaviour). I am based on (HEAD, origin/patches/LabN/R1.0.20160315+vnc/v2) bgpd: add L3/L2VPN I compiled with vnc support, and tested on ubuntu14.04 release. You can find attached the log message obtained on my console, as well as the bgp configuration used, and the wireshark capture file during the BGP exchange. Do you have an idea how I could overcome this issue ? Thanks in advance, Best Regards, Philippe ================================================================================ *error messages i had* 2016/06/06 17:08:33 BGP: %ADJCHANGE: neighbor 10.125.0.1 Up 2016/06/06 17:08:34 BGP: unknown afi/safi (0/0) 2016/06/06 17:08:34 BGP: 10.125.0.1 [Info] UPDATE with unsupported AFI/SAFI 0/0 2016/06/06 17:08:34 BGP: unknown afi/safi (0/0) 2016/06/06 17:08:34 BGP: 10.125.0.1 [Info] UPDATE with unsupported AFI/SAFI 0/0 2016/06/06 17:08:34 BGP: unknown afi/safi (0/0) 2016/06/06 17:08:34 BGP: 10.125.0.1 [Info] UPDATE with unsupported AFI/SAFI 0/0 2016/06/06 17:08:34 BGP: unknown afi/safi (0/0) 2016/06/06 17:08:34 BGP: 10.125.0.1 [Info] UPDATE with unsupported AFI/SAFI 0/0 2016/06/06 17:08:39 BGP: Import timer expired. *configuration used * hostname nva1 password zebra log stdout service advanced-vty ! router bgp 64512 bgp router-id 10.125.0.2 neighbor 10.125.0.1 remote-as 64512 ! address-family vpnv4 neighbor 10.125.0.1 activate exit-address-family vnc defaults rd 64512:1 response-lifetime 200 rt both 1000:1 1000:2 exit-vnc ! hostname nva2 password zebra log stdout service advanced-vty ! router bgp 64512 bgp router-id 10.125.0.1 neighbor 10.125.0.2 remote-as 64512 ! address-family vpnv4 neighbor 10.125.0.2 activate exit-address-family vnc defaults rd 64512:1 response-lifetime 200 rt both 1000:1 1000:2 exit-vnc ! vnc nve-group group1 prefix vn 172.16.128.0/17 rd 64512:1 rt both 1000:1 1000:2 exit-vnc !
