Reachability
Reachability indicates which VRF contains the routing information necessary to get to the server
providing the service. For example, you can configure an SNMP server that is reachable on the
management VRF. When you configure that server address on the router, you also configure which VRF
that Cisco NX-OS must use to reach the server.
Figure 14-3 shows an SNMP server that is reachable over the management VRF. You configure router A
to use the management VRF for SNMP server host 192.0.2.1.
