A junior network engineer needs to configure uRPF on a Cisco router interface to eliminate spoofed IP packets on a network. Which command should be used to configure uRPF mode when using asymmetric routing?
- ip verify unicast source reachable-via any
- ip verify unicast source reachable-via rx
- ip verify unicast source reachable-via rx allow-self-ping
- ip verify unicast source reachable-via rx allow-default
Explanation: When uRPF is configured on an interface, the uRPF mode should be chosen according to the type of routing. With asymmetric routing, a different path ends up being used for return traffic. Where asymmetric routing occurs, the uRPF loose mode should be configured. The ip verify unicast reachable-via any command configures uRPF in loose mode.
