MPLS Vpn Working Principle

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

BGP Weight Attribute

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. Currently R5 learning routes 100.100.100.1/2/3 from both R1 &

BGP Initialization

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. Currently both F0/0 port is shut no ip address, bgp configured on node. Steps: Let’s start
