What is L3 routing?
L3 routing, also known as network layer routing, involves forwarding data packets between networks based on their destination IP addresses. Routers use routing tables to determine the best path for packets to reach their destination network. It's commonly used to connect different networks, including LANs and WANs, enabling communication across the internet.
What other technologies are related to L3 routing?
L3 routing Competitor Technologies
MPLS/VPLS
MPLS and VPLS provide alternative methods for forwarding traffic, sometimes bypassing traditional IP routing. They can be used to create VPNs and offer traffic engineering capabilities, positioning them as an alternative solution to pure L3 routing for certain use cases.
EVPN
EVPN (Ethernet VPN) is a VPN technology that can extend L2 networks over an IP/MPLS core, essentially providing an alternative to pure L3 routing for connecting geographically dispersed sites.
VXLAN
VXLAN encapsulates L2 frames within UDP packets for transmission over an IP network. It's often used for network virtualization and can bypass traditional L3 routing in certain scenarios, acting as a competitor or alternative.

Route Policy
No summary available
Route policies define rules to control the advertisement and acceptance of routes, making them a crucial tool to refine and control L3 routing behavior.
ACLs
Access Control Lists (ACLs) can filter traffic based on IP addresses and other L3/L4 criteria. They are used alongside L3 routing to implement security policies and control traffic flow, making them a strong complement.
Multicast
Multicast relies on L3 routing to efficiently deliver traffic to multiple recipients. Protocols like PIM are used to build multicast distribution trees based on IP routing information.
