How to Configuration MPLS L2 VPN  between two branches: encapsulation L2 of two branches into L3 MPLS by VC & pseudo wire. How to: 1-  R2(f0/0) not assign IP   R5(f0/1) no assign IP. 2- Apply routing protocol RIP v2 on R1 & R6 . 3- Apply  OSPF on R2-R3-R4-R5, but R2 (23.0.0.0 & 2.2.2.2) no route with 16.0.0.0  and    R6 the same. 4-  Company has two branches (16.0.0.1  -   16.0.0.6) 5-  MPLS not need know network of customers into PE & P each customer so not route network into core. ----------------------------------------------------- How to Configuration routing protocol and MPLS: R1: en conf t interface f0/0 no shutdown ip address 16.0.0.1 255.0.0.0 interface loopback 0 ip address 1.1.1.1 255.255.255.255 router rip network 16.0.0.0   network 1.0.0.0    version 2 no auto-summary end wr me ------------------------------------------------------------------------------ R6: en conf t interfa

How to Configure Cisco IPSec VTI? IPSec VTIs (Virtual Tunnels Interfaces) simplifies the configuration of a VPN compared to using crypto maps or GRE IPSec Tunnels. A benefit of using VTIs does not require of tying a configuration to a physical interface, rather allowing bespoke configuration per VTI. You can use a dynamic routing protocol (EIGRP, OSPF etc) or QoS defined per VTI. The IPsec VTI allows for the flexibility of sending and receiving both IP unicast and multicast encrypted traffic on any physical interface, such as in the case of multiple paths.  Traffic is encrypted or decrypted when it is forwarded from or to the tunnel interface and is managed by the IP routing table. Using IP routing to forward the traffic to the tunnel interface simplifies the IPsec VPN configuration compared to the more complex process of using access control lists (ACLs) with the crypto map in native IPsec configurations. DVTIs function like any other real interface so that you can apply quali
