A service provider assigns two Partner Gateways to a VMware SD-WAN Edge. Which explanation is correct?
A.
If two Partner Gateways are using different AS numbers. PE router might or might not consider BGP MED metric for route selection. To avoid asymmetric routing between Partner Gateways and PE, it is recommended to utilize the BGP community mapping feature on the Partner Gateway.
B.
When the Partner Gateway advertises prefixes to Edge, the original BGP attributes such as AS-PATH are not retained.
C.
If the route prefix attribute is not identical from two different Partner Gateways, the order number of the Partner Gateways will be the tiebreaker, which means the Partner Gateway with order 1 will be used.
D.
The Partner Gateway advertises prefixes learned from the Edges to the PE router for traffic coming from MPLS to VCE. By default, the Partner Gateway with order 1 will advertise the prefix with metric 10 to the PE. The Partner Gateway with order 2 will advertise the route with metric 9 to the PE.
