DoS Protection on Cisco 7600 Routers
The Cisco7600 is one of the most versatile High End routing machines. It is one of enterprise’s networking devices. If you take a look at Cisco website under the Routers Product Category, you will notice that the Cisco 7600 can be used in Data Centers, in Service Provider networks, in WAN aggregation or as Internet Edge router. In Service Providers can be used as Provider Edge (PE) in IP MPLS networks aggregating many Customer Edge (CE) router devices. Its modularity and high port capacity allows the 7600 to work as both Layer2 aggregation and as Layer3 high performance router.
In Service Provider networks one of the main concerns of network administrators is to protect the networking infrastructure from Denial of Service attacks. These DoS attacks are actually the most serious and popular security threat against Service Providers. buy used router Botnets are frequently the main source of such attacks. ICMP flooding, UDP flooding, spoofed addresses DoS, SYN attacks etc are a few examples of DoS or DDos (Distributed Denial of Service) attacks. Fortunately the Cisco 7600 router has many robust features and mechanisms to protect itself from such attacks.
In the company that I work (Service Provider) we have already implemented several security protection features on 7600 which are really effective against DoS attacks. A summary of the DoS protection mechanisms on 7600 follows below:
- Security Access Control Lists (ACL): Applied on interfaces to block traffic at Layer3/4 layers.
- QoS Rate Limiting: Using class-maps and policy-maps you can apply rate limiting to specific type of traffic (e.g ICMP)
- uRPF (unicast Reverse Path Forwarding): protects against spoofing attacks. sell cisco routers
- Traffic Storm Control: Protects against broadcast storm attacks.
- TCP Intercept: Protects against SYN attacks.
- Hardware-Based Rate Limiters: Work on PFC3 engines. These rate limiters protect the MSFC routing engine from various packets that can overload its CPU (configured with the mls rate-limit command)
- Control Plane Policing (CoPP): Again used for protection of the MSFC routing engine by applying rate limiting to packets that flow from the data plane to the control plane.
Of course in addition to the above you must not forget other important security mechanisms such as strong password policy, proper Authentication and Accounting, refurbished cisco router logging, SNMP security, Routing Protocols security (MD5 authentication in OSPF, BGP etc) etc. All of these technical issues must be based on a thorough and carefully written security policy.

Routers, To See Different Types of Routers
More detailed classification: Internal router (IR): All interfaces belong to the same area; Area Border router (ABR): Interfaces to multiple areas; Backbone router (BR): Interfaces to backbone; Autonomous system boundary cisco router (ASBR): Exchange routing info with other autonomous systems; Designated router (DR): Generates link-state info about the subnet; Backup designated router (BDR): Becomes DR if DR fails.
If you use computers in your home or office, it is likely that your computer is connected with other computers through some type of used cisco router.Like a police officer directing traffic at an interchange, a router will direct or route information, data and files to the locations they need to go.Generally, Routers that we used can either be wired or wireless.
A wired router will generally connect to your computer and computers or hardware through an Ethernet cable. cisco 3825 router This happens with the use of output ports.And the only input port provided on a router will be used for the Internet.
A wireless router may allow access from several computers through wired Ethernet cables and through wireless connections. You will know the router you are using is wireless if it comes with an antenna. The antenna will provide the router with a specific range that allows other computers in the area with wireless capabilities to access the router, cisco 3825 price provided they have password access.
Commercial Router
If you have ever been to a coffee shop or hotel that offers Wi-Fi access, chances are they are using a commercial-grade router. These routers are much more powerful than what you would purchase at your local electronics or computer store. cisco3825 router The best commercial routers will be able to provide access to the Internet, files and printing, for example, with little problem. Commercial routers may also be used by businesses, hospitals or in a university setting as part of a wide area network or WAN.(Cisco is a leading router manufacturer to aim to provide router and networking solution to small, 3825 router medium and large enterprises) This is a network that allows computers to connect to each other even if they are in another building across town. The commercial-grade router will be used to connect with the wide area network (WAN) on one side and a smaller network called a local area network (LAN) on the other.The local area network may consist of one large office within a building.In that case, you could have multiple LANs connecting to the WAN through one or multiple routers.
Consumer Routers
If you are looking for a router for your home or small business, you likely can find what you need at your local electronics store.Generally you will want a router that serves as a wireless access point (WAP).It should also be a network switch. cisco3825 price The wireless access point (WAP) basically provides the wireless access that everyone wants.That wireless access can be both to the Internet and to other computers in the home or office.Routers that come with a network switch tend to be faster and provide more evenly distributed bandwidth to each port. Consumer routers will come in a variety of price ranges and strengths.Some of the lower priced consumer routers will not have a very strong firewall. (Cisco Linksys E-series routers, powerful home routers, are welcomed by a lot of Cisco fans, more info of Cisco’ home product store you can visit Cisco’s official site: cisco.com).

Router? Switch? Be Clear the Difference Between Router and Switch.
When someone talk about wholesale Cisco router and switch with me, I’m very confused about this. Router Switch? What are they? What are they used for? Oh, My Lady Gaga, complicated.
However, after I have found some details of switch router, it seems a little interesting. Because both router and switch are tightly related to network, to internet. If you have PCs, if you need to email to somebody, or if you want to chat with friends, they are necessarily contained. Haha, eager to get more information of router and switch. I search many details and “the difference between routers cisco and switch” through Google. Now, I’d like share some key info about router and switch.
What’s a router-switch? A router is a more sophisticated network device than either a switch or a hub. It is a device that forwards data packets across computer networks, and perform the data "traffic directing" functions on the Internet. On the Internet or on a large corporate network, for example, routers serve as intermediate destinations for network traffic. These routers receive TCP/IP packets, look inside each packet to identify the source and target IP addresses, then forward these packets as needed to ensure the data reaches its final destination. Routers for home networks (often called broadband routers) also can join multiple networks. These routers are designed specifically to join the home (LAN) to the Internet (WAN) for the purpose of Internet connection sharing. In contrast, neither hubs nor switches are capable of joining multiple networks or sharing an Internet connection.
And switch? A network switch or switching hub is a computer networking device that connects network segments. The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. By paying attention to the traffic that comes across it, it can "learn" where particular addresses are. For example, if it sees traffic from machine A coming in on port 2, it now knows that machine A is connected to that port and that traffic to machine A needs to only be sent to that port and not any of the others.
The two pieces of equipment (router and switch) look so similar and perform some similar functions, but each has its own distinct function to perform on a network. To be simple, switches create a network. Routers connect networks. A router links computers to the Internet, so users can share the connection. A router acts as a dispatcher, choosing the best path for information to travel so it's received quickly.
So what do you need? Buy cisco router or switch? After got these above, you can make sure that which you need. And more information of Cisco sale, you can visit RouterSwitch.com.
