5 important questions on Basic Network and Routing Concepts - Connecting Remote Locations with the Headquarters - Connectivity Overview
Name three main groups of VPN solutions connecting remote and branch offices
- Tunneling VPNs
- Hybrid VPNs
What is MPLS technology?
What is a Pseudowire?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Name the 2 basic Layer 2 MPLS VPN service architecture
A point-to-point technology that allows the transport of any Layer 2 protocol at the PE
- VPLS
This emulates an ethernet multiaccess LAN segment over the MPLS core and provides multipoint-to-multipoint
Name most widely deployed options of Tunneling VPNs
This is a tunneling protocol developed by Cisco that enables encapsulation of arbitrary Layer 3 protocols inside a point-to-point, tunnel-over-ip network; not encrypted.
- IPsec
Framework that uses a set of cryptographic protocols to secure traffic at Layer 3. It also secures any network application or communication that uses UP as transport protocol.
- DMVPN
DMVPN solution architecture is primarily used to better scale IPsec hub-to-spoke and spoke-to-spoke designs in large networks.
