L3 EVPN

Which of the following statements concerning PE–CE routing is FALSE?

  • A There are two methods to implement routing between the PE and CE, static and dynamic.
  • B BGP is the preferred option for PE-CE routing as it scales better than static routing.
  • C eBGP is preferred which means that the PE and CE are required to be in different autonomous systems.
  • D The CE advertises BGP EVPN route type 5 updates to the PE and the PE forwards to other PEs.
Explanation

An EVPN route type 5 is an IP-prefix route generated and advertised by a PE to remote PEs after the PE learns a local customer-side route. The CE advertises its reachable prefixes to the PE using the selected PE–CE routing method; it does not originate BGP EVPN type 5 routes. Juniper documents that locally learned PE routes are advertised to remote PEs through EVPN type 5.
