Layer 3 switches have fast switching capabilities and they have higher port ... The introduction to the Layer 3 VPN chapter discussed the two main models that exist for VPN connectivity: the overlay model and the peer model. BGP/MPLS-based Layer 3 VPNs fall within the peer model. In contrast, when an enterprise builds a Layer 2 VPN, by buying Layer 2 transport services from the service provider they are building an overlay ... The Layer 2 protocol you’re likely most familiar with is Ethernet. Devices in an Ethernet network are identified by a MAC (media access control) address, which is generally hardcoded to a particular device and doesn’t normally change. Layer 3 is the network layer and its protocol is the Internet Protocol or IP. Oct 8, 2023 · 3. Cisco 3560CX-8PC-S Layer 3 Switch.
