Which tunnel protocol will support multicast traffic?
The nodes in the network (typically network switches and routers) take care of replicating the packet to reach multiple receivers such that messages are sent over each link of the network only once. The most common transport layer protocol to use multicast addressing is User Datagram Protocol (UDP).
What types of protocol are used in VPN?
Explanation: There are six types of protocols used in VPN. These are Internet Protocol Security or IPSec, Layer 2 Tunnelling Protocol (L2TP), Point – to – Point Tunnelling Protocol (PPTP), Secure Sockets Layer (SSL), OpenVPN and Secure Shell (SSH).
When IPsec VPNs are designed what is a unique requirement if support for IP Multicast is required?
When IPsec VPNs are designed, what is a unique requirement if support for IP Multicast is required? A network engineer must connect two sites across a public network using a secure tunneling technology that supports multicast traffic.
What are the different types of VPN protocols?
Layer 2 Tunneling Protocol (L2TP): L2TP or Layer 2 Tunneling Protocol is a tunneling protocol that is often combined with another VPN security protocol like IPSec to establish a highly secure VPN connection.
What are the benefits of Cisco dynamic multipoint VPN?
Cisco ® Dynamic Multipoint VPN (DMVPN) is a Cisco IOS ® Software-based security solution for building scalable enterprise VPNs that support distributed applications such as voice and video (Figure 1). Cisco DMVPN is widely used to combine enterprise branch, teleworker, and extranet connectivity. Major benefits include:
Can a Cisco DMVPN be used with a firewall?
Cisco DMVPN can be deployed in conjunction with Cisco IOS Firewall and Cisco IOS IPS, as well as quality of service (QoS), IP Multicast, split tunneling, and routing-based failover mechanisms.
How does a virtual private network ( VPN ) work?
Virtual Private Network (VPN) is basically of 2 types: Remote Access VPN permits a user to connect to a private network and access all its services and resources remotely. The connection between the user and the private network occurs through the Internet and the connection is secure and private.
