Perform network address translation on a client router and advertise the natted address into a routing protocol, so that it will show up in the connecting network’s routing table. Do not enable the routing protocol on the client network and don’t use the redistribute static command.

Configure VRRP on two routers, providing gateway redundancy for a network.
Solution:
!RouterA ! ! Interface configuration, change FastEthernet0/0 keyword as needed interface FastEthernet0/0 ! ! IP address configured on interface ip address 10.0.0.2 255.255.255.0 ! ! Enable VRRP using a group number of 1 vrrp 1 ip 10.0.0.1 ! ! Make this router primary vrrp 1 priority 254 ! ! If a failover occurs to RouterB, make RouterA be primary again when it’s back online vrrp 1 preempt ! ! Router must have matching pw to going vrrp group vrrp 1 authentication md5 key-string abcdefghijklmino

Normally on a Unix machine, such as a firewall, the tool most would choose is tcpdump. IP accounting doesn’t quite provide this much functionality, but it certainly provides a summary of traffic passing through a router.

The router will only record packets that goes through the router. Any connections initiated from the router or terminates to the router are not counted. To view the accounting table:
