Hello community, I'm trying to connect BMs to contrail network as described here [0]. I'm using the following versions:
OpenContrail - 3.1.1 QFX 5100 - QFX5100-48S-6Q (JunOS 14.1X53-D45.3) I have 1 VM (ip: 10.20.30.68 mac: 02:46:d6:34:c0:b0) running on compute node (compute node ip: 172.16.175.103). And 1 BM (mac: ac:de:48:6b:e4:e4 ip: 10.20.30.11) connected to ToR (BM interface: xe-0/0/1, ovsdb tunnel/management IP: 192.168.10.1). VTEPs are being created fine on ToR switch to both compute nodes and ToR. Tunnel between ToR and TSN (tunnel ip: 172.16.175.61) is up, When try to ping VM from BM or vice versa failed on ARP resolution. When I add static ARP entries ping works. On TSN node I see both arp requests from BM and replies to BM, but for unknown reason they never reach BM. If you have any ideas why it may happen please help.
