OSPF States are the different stages a router goes through when establishing and maintaining neighbor relationships in an OSPF network.
OSPF states include Down, Init, 2-Way, Exstart, Exchange, Loading, and Full.
During the Down state, the router has no information about its neighbors.
In the Init state, the router sends Hello packets to discover neighbors.
2-Way state is when bidirectional communication is established bet...
There are several BGP attributes used for path selection and routing decisions.
There are well-known BGP attributes like AS_PATH, NEXT_HOP, LOCAL_PREF, etc.
There are optional BGP attributes like COMMUNITY, ORIGINATOR_ID, CLUSTER_LIST, etc.
There are also extended BGP attributes introduced in newer versions of BGP.
BGP attributes are used by routers to make routing decisions and determine the best path to a destination.
A VLAN (Virtual Local Area Network) is a logical grouping of devices on the same physical network, allowing for segmentation and improved network performance.
VLANs are used to separate broadcast domains in a network.
They can improve network security by isolating traffic between different VLANs.
VLANs can be configured based on port, MAC address, or protocol.
Example: VLAN 10 for finance department, VLAN 20 for marketing
DWDM stands for Dense Wavelength Division Multiplexing, OSPF is Open Shortest Path First, EIGRP is Enhanced Interior Gateway Routing Protocol, OLT is Optical Line Terminal, and ONU is Optical Network Unit.
DWDM is a technology that multiplexes multiple optical carrier signals on a single optical fiber by using different wavelengths of laser light.
OSPF is a routing protocol used for exchanging routing information between...
Yes, CCNA certified. EtherChannel is a technology used to combine multiple physical links into a single logical link for increased bandwidth and redundancy.
EtherChannel is a Cisco proprietary technology used to bundle multiple physical links into a single logical link.
It provides increased bandwidth and redundancy by load balancing traffic across the links.
EtherChannel can be configured in different modes such as on, a...
BGP stands for Border Gateway Protocol, a routing protocol used to exchange routing information between different autonomous systems on the internet.
BGP is used to make routing decisions based on network policies, rules, and paths.
It is a path vector protocol that allows routers to share information about the best path to reach a certain destination.
BGP operates on TCP port 179 and uses TCP connections to exchange rout...
Fiber cable is a high-speed data transmission cable made of glass or plastic fibers.
Fiber cable is used for transmitting data over long distances.
It is made up of thin strands of glass or plastic fibers that are bundled together.
Fiber cable is faster and more reliable than traditional copper cables.
It is commonly used in telecommunications, internet, and cable TV networks.
Fiber cable is also used in medical equipment a
The power required for fiber cables varies depending on the type and length of the cable.
Single-mode fiber cables typically require less power than multi-mode fiber cables.
The power required also depends on the length of the cable and the number of connections.
For example, a 10 km single-mode fiber cable may require around 1 watt of power.
However, a 10 km multi-mode fiber cable may require up to 10 watts of power.

A fast connector is a pre-polished, field-installable fiber optic connector that eliminates the need for epoxy and polishing.
Fast connectors are used to terminate fiber optic cables quickly and easily in the field.
They are designed to be installed without special tools or training.
Fast connectors are available in various types, including SC, LC, and ST connectors.
Examples of fast connector brands include 3M, Corning, a

The R45 code refers to a specific standard or regulation related to fiber engineering.
The R45 code is used in the field of fiber engineering to ensure compliance with specific standards and regulations.
It may refer to a code or specification that outlines the requirements for fiber optic cables, connectors, or installations.
The R45 code may vary depending on the country or organization, so it's important to understand
