## With calico it is possible to distributed routes with border routers of the datacenter.
## Warning : enabling router peering will disable calico's default behavior ('node mesh').
## The subnets of each nodes will be distributed by the datacenter router

# Configure the MTU to use for workload interfaces and tunnels.

# - Otherwise, if IPIP is enabled, set to your network MTU - 20
# - Otherwise, if not using any encapsulation, set to your network MTU.
