The amount required is roughly # proportional to the number of Neutron routers that will be scheduled to # that host. It is necessary to reserve memory on the compute nodes to avoid # memory issues when creating instances that are connected to routed # networks. The current expected consumption is 50 MB per router in addition # to the base reserved amount. Deployers should refer to existing # documentation, release notes, etc. for additional information on estimating # an appropriate value. The provided value here is based on an estimate of 10 # routers and is an example value *only* and should be reviewed and modified # if necessary before deploying.
