Overview

Command evr is a VXLAN-based EVR probing tool.

It sends UDP/VXLAN packets to one or more EVR VTEPs, where each probe carries an inner Ethernet/IPv4/UDP frame whose inner src/dst IPs both equal the local probing machine's address. The actual EVR src IP is embedded inside the payload so the EVR's reflection can be matched back to the originating target.

Usage:

evr -c evr.json
evr --client-addr 10.0.0.1 --targets 10.0.1.10#192.168.100.1
evr -c evr.json --rate-in-span 5000   # CLI overrides config file
