LinuxCon + CloudOpen + ContainerCon NA 2015

For most of it's existence the default behavior for the Linux kernel has been what most would consider a 'weak host' model. This will means that the kernel will chose to forward frames by any means necessary to ensure connectivity between a source and destination. Unfortunately one of the system states not taken into consideration when making a routing decision is outgoing link-state. In the past, the Linux kernel has relied on an array of userspace applications to solve this problem and either remove routes or perform configuration changes when link state changes. This talk will cover recent kernel changes that provide a configuration option to change route table behavior based on link-state, the benefits of this in the kernel for users and administrators, and possible future development plans for this feature.
