Limit network traffic to increase network performance. For example, if corporate policy does not allow video traffic on the network, ACLs that block video traffic could be configured and applied. This would greatly reduce the network load and increase network performance. 2. Provide traffic flow control. ACLs can restrict the delivery of routing updates. If updates are not required because of network conditions, bandwidth is preserved. 3. Provide a basic level of security for network access.

Hello, welcome to Routing Fundamentals. Just like it is important to understand how networks operate in order to secure them, it is also critical to understand how routers and routing work in order to have a secure network. What allows people from all over the world to communicate and what allows the Internet to function is routers. Routers are responsible for determining the path and sending traffic from source to destination.

The Internet Key Exchange (IKE) protocol, described in RFC 2409, is a key management protocol standard which is used in conjunction with the IPsec standard. IPsec can be configured without IKE, but IKE enhances IPsec by providing additional features, flexibility, and ease of configuration for the IPsec standard. As mentioned in the T_IPsec chapter, IPsec security associations (SAs) must exist in order for IPsec to protect network traffic. IKE manages those SAs on behalf of IPsec, and automatically negotiates protection policies between IPsec peers. ...
