1. CASE PRINCIPLE

Vyatta versione: VC 3.0 Oct 29, 2007
ATTENZIONE, QUESTO CASO STUDIATO NON E’ STATO VALIDATO

La configurazione sotto è solo a titolo informativo!!!

Abbiamo notato che in Vyatta VC 3.0 l’istradamento OSPF -> BGP crashia.



Sfortunatamente, non possiamo offrire I risultati dei test perchè alcuni bugs fanno crashiare bgp routing table.

BE CAREFUL, THIS CASE STUDY HAS NOT BEEN VALIDATED

The configurations provided are for information ONLY!!!

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