VRouter on VMware ESXi hardware specs
Here are the specs for Contrail VM that we recommend:
VCPUS – 2, MEMORY – 8Gb, HW
Compatibility – 6.0 or later, Linux Version – 3.13.0-40-generic
By default Contrail vRouter is having about 520K flows (see below). I guess that we are pre-allocating memory for installing those flows.
We can increase this value and for instance to 2M.
root@contrail:~# vrouter --info | grep "Flow Table limit"
Flow Table limit 524288
