Unfortunately, these namespaces can not be used with actual switching
ASICs, as their ports can not be migrated to other network namespaces
-(dev->netns_local) and most of them probably do not support the
+(dev->netns_immutable) and most of them probably do not support the
L1-separation provided by namespaces.
However, a similar kind of flexibility can be achieved by using VRFs and
projects / linux-block.git / commitdiff
