How to Configure HSRP on Cisco Router in Packet Tracer

HSRP, short for Hot Standby Router Protocol, is a first-hop redundancy protocol that allows multiple routers to collectively serve as the default gateway for high-priority host devices/subnetwork. At any given time, one of the routers serves as the active default gateway, while the others act as backups. In the event of the active router’s failure, […]

How to Configure IPV6 Static Route in Packet Tracer

In our recent post, we demonstrated how to configure IPv4 static routing. Similarly, IPv6 static routes can also be configured on a IPV6 network to enable a router to learn routes to networks not directly connected to it. In this particular post, we will configure both static routes and floating static routes. A floating static

Configuring IPV6 Address Using EUI-64 Interface ID in Packet Tracer

In this post, I will show you how to configure IPv6 addresses on an interface using Modified EUI-64 in Packet Tracer. EUI stands for Extended Unique Identifier, also referred to as EUI-64. It is a method of converting a MAC address (48 bits) into a 64-bit interface identifier. This interface identifier will now be the

How to Configure IPV6 Address in Cisco Packet Tracer

In this post, I will show you how to configure IPv6 addresses in Cisco Packet Tracer. In this demonstration, we will practice configuring IPv6 addresses on both a Cisco router and PCs. There are two primary types of IP addresses: IPv6 and IPv4. In the early days of networking, IPv4 served as the primary IP

How to Configure VLSM in Cisco Packet Tracer

Variable Length Subnet Mask (VLSM) is a method of dividing a large network into multiple smaller subnetworks with a varied number of usable IP addresses. VLSM is used when the LANS within a network have a high variation in the number of host devices. For instance, a large network may consist of four LANs: LAN

How to Configure PPPoE Client on Cisco Router

Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol that facilitates communication between network endpoints. PPPoE encapsulates Point-to-Point Protocol (PPP) frames within Ethernet frames, offering the same benefits as PPP while providing connectivity across Ethernet networks. PPP (Point-to-Point Protocol) is a data link protocol used to establish a direct connection between two nodes in a

How to Configure OSPF Plain Text Authentication

OSPF authentication can be configured on OSPF routers to prevent rogue routers from injecting false routing information and causing a Denial-of-Service attack. There are two types of OSPF authentication: Plain Text authentication and MD5 authentication. Plain text authentication uses clear text passwords, while MD5 authentication provides a more secure method. In this post, we will

Configuring OSPF Hello Timer

The OSPF hello timer dictates the frequency at which an OSPF router sends hello packets to its OSPF neighbors. These hello packets help to verify the activity status of neighboring routers or to initiate a new neighbor relationship. The OSPF hello interval varies depending on the OSPF network type. For Ethernet interfaces, the default OSPF

Configuring Rapid-PVST, PortFast and BPDU Guard in Cisco Switch

Rapid-PVST, PortFast, and BPDU Guard are three layer 2 technology that work together to prevent accidental loops in the network and also enhance immediate access to the network when a host device is plugged into a switchport. When connecting multiple switches together, they undergo a negotiation process to determine the root bridge and non-root bridges.

How to Configure “GRE over IPSec Tunnel” on Cisco Routers (Site-to-Site)

GRE (Generic Routing Encapsulation) creates tunnels like IPSec; however, it does not encrypt the original packet, so it is not secure. Nevertheless, it has the advantage of being able to encapsulate a wide variety of Layer 3 protocols as well as broadcast and multicast messages. To achieve the flexibility of GRE with the security of
