Topology
Summary:
To implement Flex VPN or IPSEC VPN the topology shown above. The motive is to make the reachability between LAN to LAN network i.e from 20.20.20.0 to 30.30.30.0 & vice versa.
Currently we have configure simple connectivity in which R1 and R2 is reachable to each other via internet cloud.
The basic requirement of any VPN is the rechability between source and destination end point of 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:
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 plane protocols: LDP and MP-BGP to accomplish MPLS VPN communication.
LDP used for signaling and responsible for distributing label among LSR, however LDP rely on IGP for choosing the best path.MPLS unicast ip forwarding is purely based on IGP and LDP.
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.
