Hi, I've got strange behaviour: 1. The VPP transit link goes down (this link not directly connected). To be honest it was blocked by spanning tree on transient switch. 2. After the issue was resolved link not came up, it simply doesn't work. I'm using 10.0.0.0/31 p2p network on that link. Address .0 is router and .1 is vpp host. 3. I'm trying to look at the arp table on the router (address 10.0.0.0) and see nothing. 4. To resolve this issue I've tried to ping from the router (success) and then back from vpp to the router (success)
Moreover looks like network on the interface with mask /25 comes up without manual intervention. Is /31 p2p addresses are not recommended to use on vpp links. P.S. This interface is dot1q vlan 100 with p2p network /31 and 200 with /25 network.
