It will create a BGP topology with OSPF, RSVP-TE and Targeted LDP # # configured in Area Border Router. # # 2. In Provider Edge Router configuration BGP Peer is configured. # # 3. BGP VRF is configured on top of BGP Peer. # # 4. IPv4 & IPv6 Prefix Pools are added behind BGP VRF. # # 5. IPv4 and IPv6 addresses are configured in IPv4 and IPv6 Prefix Pools. # # 6. Label values are configured in V4 & V6 Prefix Pools. # # 3. Only one side configuration is provided. # # 4. Traffic configuration will be similar to L3VPN scenario. # ################################################################################ import os import sys import time def assignPorts (ixNet, realPort1, realPort2) : chassis1 = realPort1[0] chassis2 = realPort2[0] card1 = realPort1[1] card2 = realPort2[1] port1 = realPort1[2] port2 = realPort2[2] root = ixNet.getRoot() vport1 = ixNet.add(root, 'vport') ixNet.commit() vport1 = ixNet.remapIds(vport1)[0] vport2 = ixNet.add(root, 'vport') ixNet.commit() vport2 = ixNet.remapIds(vport2)[0] chassisObj1 = ixNet.add(root + '/availableHardware', 'chassis') ixNet.setAttribute(chassisObj1, '-hostname', chassis1) ixNet.commit() chassisObj1 = ixNet.remapIds(chassisObj1)[0] if (chassis1 != chassis2) : chassisObj2 = ixNet.add(root + '/availableHardware', 'chassis') ixNet.setAttribute(chassisObj2, '-hostname', chassis2) ixNet.commit() chassisObj2 = ixNet.remapIds(chassisObj2)[0] else : chassisObj2 = chassisObj1 #
