Securing routers Routers are the basic level of the Internet. It is responsible for the communication through the network‚ between computers and servers. It is important to secure the routers so the attackers can’t gain information from the routers. There are many ways of securing the routers such as upgrade the operating system‚ warning banners and disable unneeded services. Hardening cisco routers Upgrade IOS One of the important parts of securing routers is to choose the right router operating

protocol. Suppose eBGP and iBGP are used for the inter-AS routing protocol. Initially‚ suppose there is no physical link between AS2 and AS4. * Router 3c learns about subnet with prefix x from which routing protocol: OSPF‚ RIP‚ eBGP‚ or iBGP? eBGP * Router 1d learns about subnet with prefix x from which routing protocol? iBGP * Once router 1d learns about x it will put an entry (x‚I) in its forwarding table. Will I be l1 or l2 for this entry? Explain your answer briefly. I1‚ the interface

conduction of electricity from one conductor to another.Wall switches are switches that are most commonly used in managing the light fixtures and permanent devices or equipment. Switches are connected using different methods such as three-way and four-way switches‚ grounded conductors and switches controlling light loads. The three-way and four-way connection method is simply used to create lights that operate using more than one switches; mostly done to change the states of light (Brain‚ 2009). Grounded
