Tunnel name provisioned on BIG-IP by f5-oslbaasV1-agent can not exceed 64 Bytes

[G5unit]

Agent Version

f5-oslbaasv-agent version 2.0.1, downloaded from devcentral.f5.com .

Operating System

I was able to reproduce this in environments running Centos7 (& Ubuntu15.10 though I do not have logs to share from that platform right now). BIG-IP VE version ran is 12.0 .

OpenStack Release

Liberty

Description

When provisioning access to tenant networks on BIG-IP, F5 LBaasV1 agent creates a tunnel on BIG-IP. Name of this tunnel is composed of several things including "environment_prefix" variable set in f5-oslbaasv1-agent.ini file. There seems to be a limit on length of tunnel name being provisioned, limit of 64 bytes.
When "environment_prefix" in f5-lbaasv1-agent is set to environment_prefix = uuidCentos7 I got these errors:

Reducing the length of "environment_prefix" made things work.
environment_prefix = Cos7
This is probably just a partial workaround as tunnel name depends on other factors, not just "environment_prefix".

Deployment

Single OpenStack controller with one F5 agent managing single external BIG-IP. OpenStack uses a flat provider network for public access, and OVS VXLAN for overlay networking.
