IPv6 Migration: 6 to 4 Tunnelling Explained with Example.

What Is 6 to 4 Tunnelling? 6 to4 tunnelling is a method of integrating IPv6 packets within an IPv4 network. It is particularly useful when transmitting IPv6 data over an IPv4 network, and is especially effective in WAN settings where a remote network still uses IPv4 protocols. In this type of migration, the process involves the creation or… Read More »

Router-on-a-Stick InterVLANs Sub-Interfaces.

What Is Router-on-a-Stick Inter-VLANs Sub-interfaces? Router-on-a-Stick Inter-VLANs is a network setup that enhances communication between various VLANs on a single network device. It Involves connecting a single physical interface of a router to a switch, along with configuring multiple logical sub-interfaces on the router. This setup allows for the routing of traffic between different VLANs without the need… Read More »

Access Control Lists (ACLs).

What Is an Access Control List? Access Control Lists (ACLs) are filters that enable you to control which routing updates or packets are permitted or denied in or out of a network. They are specifically used by network administrators to filter traffic and provide extra security for their networks. This can be applied to routers (Cisco). ACLs provide… Read More »

EIGRPv6 Passive Interface.

What Is EIGRPv6 Passive Interface? EIGRPv6 Passive Interface refers to a specific configuration in Enhanced Interior Gateway Routing Protocol (EIGRP) for IPv6, where an interface is set to ‘passive’. This configuration prevents EIGRPv6 from sending or receiving routing updates on that interface, conserving network resources and bandwidth. It is commonly used on interfaces where EIGRPv6 routing information is… Read More »

EtherChannel Configuration on Cisco Switches.

By configuring EtherChannel, we bundle multiple physical connections between two or more Cisco switches into one logical link. This allows for increased bandwidth, improved fault tolerance, and load balancing across the aggregated links. EtherChannel also provides a more efficient use of available network resources and simplifies the management of network connections between switches. In a conventional network where… Read More »
