In the fabric network with dual border node networking in the campus distributed gateway solution, cross-networking is recommended between the core device and the aggregation device, so that L3VXLAN tunnels are created between the two border nodes and the edge node. In this scenario, Regarding the high-reliability design of the traffic model for egress traffic, the incorrect description is:

In the fabric network with dual border node networking in the campus distributed gateway solution, cross-networking is recommended between the core device and the aggregation device, so that L3VXLAN tunnels are created between the two border nodes and the edge node. In this scenario, Regarding the high-reliability design of the traffic model for egress traffic, the incorrect description is:
A . The two upstream traffic paths on edge form ecmp load balancing
B . Select different main exits for different source network segments.
C . Different edge devices select different main exits.
D . Select different main exits for different uplink network segments.

Answer: B
