http://unix.stackexchange.com – I have to create virtual interface for control plane algorithms for layer 2 protocol algos..... Scenarios is somewhat like this.... Control plane will be executing on Centralised card executing Control Plane logic..... Data plane will be part of line cards executing fast path switching and routing....... My requirement is I have to create virtual interfaces at Control plane which should map to actual interface on Line cards. Can I use TAP for this..........?? (HowTos)
