Spirent TestCenter: Is it possible to modify the LS Update packet size to fit the port MTU?

  • Spirent TestCenter.
  • OSPF.
The more LSAs you send, the bigger the LSA Update message is.  Please refer to the images below:
  • 10,000 LSA's
  • 30,000 LSA's
  • 50,000 LSA's
It's not possible to modify the OSPF message headers; so, the best option to reduce the LS Update packet fragmentation, is to increase the MTU value.
enlightenedNOTE: The MTU must be the same, either in Spirent TestCenter and the DUT for the OSPF adjacency to come up.enlightened
