# This script will demonstrate Bonded GRE as per RFC 8157                      #
#     Script  will do following:                                               #
#    1. Load the config bonded_gre_sample_script.ixncfg                        #
#        Config has following:                                                 #
#        a. Config having HAAP side simulation pre configured                  #
#        b. Client side Bonded GRE will be configured in this sample           #
#    2.  Create Bonded GRE topology                                            #
#    3.  Create Link TLV {[77] Link Type]}                                     #
#        and custom TLV {[xx] Bonded GRE Custom TLV}                           #
#        These TLV 's are not mandatory to create                              #
#    4.  Start Protocol in following order as start all protocol not supported #
#        a. Start LTE Bonded GRE device group                                  #
#        b. Start DSL Bonded GRE device group                                  #
#        c. Start HAAP GRE   												   #
#		 d. Simulate control traffic after starting device group mentioned in  #
#			steps from (a to c) for LTE and DSL setup Accept message so that   #
#			Bonded GRE to come up.                                             #

#        e. Start Home Gateway dhcp client                                     #
#    5. Create data traffic between HomeGateway DHCP Client to DHCP IPv4 Server#
#    6. Send Active Hello Notify packet from HAAP to Home Gateway.             #
#    7. Send right click actions like stop hello, resume hello, overflowLte    #
#    8. Check following session info state:                                    #
#       a. Bonded Gateway Session Info                                         #

#	 9. Send LTE tear down control traffic from HAAP to HG  	               #
#    10. Stop and start Bonded GRE LTE after tear down                         #
#    11. Send Tear Down from Home Gateway to HAAP with error code 11           #
#    12. Check     Stats                                                       #
#    13. Stop Protocols                                                        #
