From 7a32c18b2fb3f220f099218871ba29115ef31ee9 Mon Sep 17 00:00:00 2001 From: Ross Brattain Date: Sun, 21 May 2017 21:07:50 -0700 Subject: add network info to topology we need to know which network each port is connected to so we can find VLAN or VXLAN ID. To do this we implement a new method for Contexts, Context.get_network(). This method is similar to Context.get_server(), it searches for a given network name in all the contexts. From this we generate a context_cfg["networks"] dict that stores all the network info for the nodes in the scenario. Then when we generate the topology for VNFD, we can lookup a given network by the vld_id and get the network_type, segmentation_id, etc. Then if we need to for example generated traffic on a given VLAN or VXLAN, we have this info available. Define default nd_route_tbl for ACL VNF we need default empty nd_route_tbl for IPv6 route.
