It detects malicious attacks against the network and logs them on a server. It can filter traffic based on the protocol and port numbers. It encrypts traffic between hosts.

Refer to the exhibit. EIGRP has been configured on all routers in the network. Based on the outputs from the show ip route commands on R1 and R2, how will the routers process traffic from Host2 to the hosts on the 172.16.11.0/24 and 172.16.12.0/24 networks?
