Topology Objectives Create Gre tunnel between Router A and Router c. We are creating tunnel to internal communication between two LAN segments without, advertising LAN IP in internet domain. Steps: Your end to end network should be reachable i.e the interface/node from where you are creating tunnel should reachable to destination interface/node. Here Router A…
Topology: Objective: To test the broken LSP failover using LDP protocol. All router in the topology are running under OSPF area 0.LDP has been enabled between them. Currently LDP synced and LDP neighbor ship has been established between all routers.
Topology: Objective: Configure MPLS L3VPN and understand it’s working. Currently PE1 & PE2 running iBGP under AS 100.PE1, P1, P2 & PE2 running OSPF as IGP. MPLS backbone running LDP for label distribution, LDP neighbor ship has been established among PE1, P1,P2 and PE2.CE1/CE11 using default routing towards PE1/PE2 respectively. MPLS VPN used two control…
Topology Objectives Use BGP attribute to influence the route selection in BGP. Currently Router R1/R1 running iBGP .Between R1-R3 & R2-R4 ebgp is used. Within ISP we have used Full iBGP mesh ( of course we could have used RR).Connect the network as shown in topology.
Topology Objectives Objective is to understand how bgp initialize when you enable interfaces and bgp parameters. We will check it by sniffing tool Wireshark to know what happening behind the scene. Wireshark will be enabled on f0/0 on R2.
Topology Objective: To implement BGP over GRE , the topology shown above. In topology R1 & R3 running BGP 100 whereas R2 running only IGP.R1-R4 & R3-R5 running ebgp and advertising prefix 4.4.4.4 and 5.5.5.5 respectively. R1-R2-R3 running ospf under area 0. Bgp over GRE can be configured in scenario where end to end BGP…
Today we will see the different Ethernet frame types and there header size. 1)Ethernet encapsulation 802.3 2)Ethernet encapsulation 802.1q Frame 3)Ethernet encapsulation 802.1ad 4)Ethernet encapsulation 802.1ah
Types Of VPN in Networking We are having different techlogy when it comes to secure the private network over internet for securely sharing your data in public domain.The figure above depicts the types of VPN services that we can use as per our requirement.We will see each VPN and their features with configuration ahead.
IPv4 Packet The header fields are discussed below: Version (always set to the value 4 in the current version of IP) IP Header Length (number of 32 -bit words forming the header, usually five) Type of Service (ToS), now known as Differentiated Services Code Point (DSCP) (usually set to 0, but may indicate particular Quality…
