IxNetwork NGPF: Configure 2 BGP peers and run traffic to prefix list

Scenario:
Configure a eBGP session  between  2  peers that are running BGP over their loopback interface. 
Inject a prefix list  in BGP and run traffic to it from the  neighbour.







Create a BGP peer:
1. Create a topology having one device group with Protocol IPv4 and IPv4 loobback enable

2.Configure interface IP

3. Configure  IPv4 loopback address

4.  Add protocol over IPv4 loopbak  interface

4.a Select BGP  over Ipv4 loopback address

5. Configure BGP

5.a  Enable filter IPv4 unicast on Learned routes Filter  if you want to see the learned routes in real time









Advertise routes:
6. Add a network group over BGP

6.a Chose Network group type a prefix

6.b Configure the prefix

*** repeat  the first 5 steps for  the second BGP peer

Start scenario
7. Check that routes are advertised using statistics
8. Check the learned routes on the BGP peer
8.a On the peer that is receiving the routes right click on the peer and select Get IPv4 Learned info

8.b Check that all routes are displayed



Send traffic from  Device 2 physical interface 10.10.1.2 to  all prefixes  advertised by its BGP peer

9.a Set the source address as 10.1.1.2

9.b Set the destination address as the prefix list

9.c Enable flow tracking on  IP Destination  Address so you can check that all prefixes are served
9.d Check the flows in Preview 

9.e Start traffic and on Traffic Item tab drill down per destination IP

  1. I need some help on how to use the IXIA platform. I need to send multiple traffic streams using IXIA to a switch. I need to capture the packets for a total duration of 25 seconds. I send first traffic stream. After 50K packets of first stream, I start the second stream, so that I send 2 traffic streams simultaneously. Later, I start the remaining streams. I need to do this automatically using IXIA, because the time duration of 25 sec is very critical for observations. Please tell me how to implement this using IXIA (using GUI/using script)

    1. you did not see the update traffic because IxNetwork introduce a signature in the traffic item and is filtered out when you capture control packets, plus you cannot simulate the TCP session with IxN traffic.
      the only way to continuously send updates from IxN is to create a very big prefix list to send over BGP

    2. ixiangpf .. python libraries traffic_config()..

  2. Is there an option to configure BGP MD5 authentication on the IXIA as I am trying to simulate a customer network in the lab.

  3. Hi, is it possible to use ixia as router between two fits , say ixia--dut --ixia router-- dut-- ixia
