1. CASE PRINCIPLE

BE CAREFUL, THIS CASE STUDY HAS NOT BEEN VALIDATED

The configurations below are for information ONLY!!!

We noticed that under Vyatta VC 3.0 the OSPF -> BGP redistribution leads to the BGP process crash.



Unfortunately, we cannot provide you the results of our tests because of some bugs crashing the bgp routing table.
Read the Vyatta policy about the Community Edition.
