What does ip cef mean?
Cisco Express Forwarding
Cisco Express Forwarding (CEF) is an advanced layer 3 switching technology used mainly in large core networks or the Internet to enhance the overall network performance.
How do I check my cef?
Alternatively, applicants can enquire through the Continuing Education Fund (CEF) 24-hour hotline at 3142 2277, or SFO E-Link (https://www.wfsfaa.gov.hk/cef/en/elink.htm) for the accounts information.
What is ip cef Cisco command?
Cisco Express Forwarding, CEF is advanced Layer 3 IP switching technology used on cisco router and switch. It is a feature that allows a router to quickly and efficiently make a route lookup. CEF optimizes routing table lookup by creating a special, easily searched tree structure based on the IP routing table.
What is cef process?
CEF 3 is a multi-process implementation based on the Chromium Content API and has performance similar to Google Chrome. It uses asynchronous messaging to communicate between the main application process and one or more render processes (Blink + V8 JavaScript engine).
How does IP CEF work?
From a 500 foot view CEF is a method the router uses to forward packets, without utilizing any CPU cycles. CEF works by creating two tables: The Adjacency table maintains the layer 2 forwarding information for each FIB entry eliminating the need for the router to send out ARP requests.
How do I enable my CEF ip?
To enable CEF, use the ip cef command in global configuration mode. Enable dCEF when you want your line cards to perform express forwarding so that the route processor (RP) can handle routing protocols or switch packets from legacy interface processors.
What is CEF table Cisco?
Cisco Express Forwarding (CEF) is advanced, Layer 3 IP switching technology. CEF optimizes network performance and scalability for networks with large and dynamic traffic patterns, such as the Internet, on networks characterized by intensive Web-based applications, or interactive sessions.
How is CEF implemented?
Application Structure
- Provide an entry-point function that initializes CEF and runs either sub-process executable logic or the CEF message loop.
- Provide an implementation of CefApp to handle process-specific callbacks.
- Provide an implementation of CefClient to handle browser-instance-specific callbacks.
What is CEF DLL?
This DLL can be used to embed an instance of Chromium browser in a window of your application. Is written in C++ in Win32. Has been tested in Windows XP( 32 bits ) and in Windows 8.1( 64 bits ).
What is the CEF table?
CEF is a packet switching technique, whereas IP routing is a technique of forwarding packet along the best path toward destination. CEF contains two bodies i.e. adjacency table which is layer 2 and FIB which is layer 3. On contrary, IP routing table is layer 3.
