Gre Tunnel

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…

MPLS lsp path broken

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. As depicted in topology Router R2 have two path to reach to Router R9…

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…
