[vpp-dev] VXLAN Instances Not Freed Properly?

[Jon Loeliger]

John, et al,

I stumbled across this interesting behavior in VXLAN tunnels:

vpp# create vxlan tunnel src 1.2.3.4 dst 10.11.12.13 vni 1 instance 101
vxlan_tunnel101
vpp# create vxlan tunnel src 1.2.3.4 dst 10.11.12.13 vni 1 instance 101 del
vpp# create vxlan tunnel src 1.2.3.4 dst 10.11.12.13 vni 1 instance 101
create vxlan tunnel: Instance is in use

And note the actual interface has been removed, so 101 should be free:

vpp# show int
              Name               Idx       State          Counter
Count
TenGigabitEthernet6/0/0           1        down
TenGigabitEthernet6/0/1           2        down
TenGigabitEthernet6/0/2           3        down
TenGigabitEthernet6/0/3           4        down
local0                            0        down

I was pretty sure this was working, but I might have botched that patch
somehow?
Any chance you stumbled into this problem?

It might be worth noting that the equivalent GRE does work:

vpp# create gre  tunnel src 1.2.3.4 dst 10.11.12.13 instance 14
gre14
vpp# create gre  tunnel src 1.2.3.4 dst 10.11.12.13 instance 14 del
DELETED
vpp# create gre  tunnel src 1.2.3.4 dst 10.11.12.13 instance 14
gre14

I feel like this might be some typo or easy oversight in the VXLAN case.

Thanks,
