STP
Agenda What is STP and why do we use STP? How STP Works? STP Feature like Port fast , BPDU Guard, Root Guard Direct vs Indirect failure 1. STP is a layer 2 Protocol which is used to avoid loops and provide path Redundancy. STP is defined as IEEE 802.1D standard. 2. STP use messages […]
VLAN
Agenda Basic Function of switch and switching method. Introduction of LAN and VLAN Why we create VLAN? Type of Layer 2 switchport What is Trunking and Type of trunking Protocol? Introduction of DTP Introduction of Native VLAN Inter-VLAN Routing Practical scenario What is Private VLAN and how to configure Private VLAN? Switch function at Layer […]
VPN
A virtual private network (VPN) extends a Private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. (“In the simplest terms, it creates a secure, encrypted connection, which can be thought of as a […]
GRE
Agenda What is GRE? Why we need GRE? How to configure GRE and how it works? Practical scenario Tunneling is a mechanism where we encapsulate a packet into another packet. Basically we can think tunneling as adding or removing protocol header. GRE (Generic Routing Encapsulation) GRE is a tunneling protocol originally developed by Cisco that […]
BGP II
RR (Route Reflector): As we know BGP have loop prevention mechanism for iBGP where Route learned from an iBGP peer must not be advertised to any other iBGP Peer. Therefore we have a requirement where all iBGP Peer should be connected in logical Full mesh topology to exchange route information and this is not scalable […]
BGP
Basic things about BGP: BGP is an open standard Protocol. Currently we are using Version 4. BGP is a path vector routing protocol. BGP uses a list of AS number through which a packet must pass to reach destination and this list describe the path a packet must take that’s why BGP is called Path Vector […]
OSPF II
OSPF is an interior gateway protocol (IGP) for routing Internet Protocol (IP) packets solely within a single routing domain, such as autonomous system. It gathers link state information from available routers and constructs a topology map of the network. The topology is presented as a routing table to the Internet layer which routes packets based […]
OSPF
Agenda Introduction of OSPF and how OSPF works. What is Area and Advantage of Area? OSPF Neighbor Table and database table and Routing Table. OSPF Packet Type OSPF Neighbors LSA Header and Types DR (Designated Router)/BDR (Backup Designated Router) Special Area Type OSPF Authentication OSPF is a “Open standard” routing protocol. OSPF is a […]
