LSR is emulated in the front Device Group(DG), which consists # # of both OSPF as routing protocol as well as RSVPTE-IF for Label # # Distribution Protocol. The chained DG act as LER, where RSVP-TE P2MP LSPs # # are configured. Unidirectional L2-L3 Traffic from Ingress to Egress is # # created. # # Script Flow: # # Step 1. Configuration of protocols. # # Configuration flow of the script is as follow: # # i. Adding of OSPF router # # ii. Adding of Network Topology(NT) # # iii. Enabling of TE(Traffic Engineering) # # iv. Adding of chain DG # # v. Adding of RSVP-TE LSPs within chain DG # # Step 2. Start of protocol # # Step 3. Protocol Stat display # # Step 4. Learned Info display # # Step 5. Configuration L2-L3 Traffic # # Step 6. Apply and Start of L2-L3 traffic # # Step 7. Display of L2-L3 traffic Stats # # Step 8.Stop of L2-L3 traffic # # Step 9.Stop of all protocols # # # ################################################################################# 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 #
