In an NSX environment, an administrator is seeing low throughput and intermittent congestion between the Tier-0 Gateway and the upstream physical routers. The environment was built for high availability and load balancing, with two Edge Nodes deployed in Active/Active mode.

Which two actions would resolve the low throughput and congestion?

Choose two
Explanation

ECMP on an active/active Tier-0 Gateway load-shares traffic across equal-cost uplink paths instead of concentrating flows on a limited path set. Deploying additional Edge nodes scales out the Tier-0 forwarding capacity and increases the available paths to the physical network. Broadcom documents that ECMP uses five-tuple hashing to distribute traffic across available paths and identifies adding an Edge node to the Tier-0 service-router cluster as a topology change that mitigates ECMP-related path-distribution issues.
