Frame-relay L2TPv3 Issue

In this example we will configure L2TPv3 between our PEs (R2, R3) in order to achieve IPv4 and IPv6 connectivity between our CEs (R1, R4)
Routing protocol is use between the CEs is RIP version 2

Configuration

R1

R1#sh run int lo0
interface Loopback0
ip address 1.1.1.1 255.255.255.255
ipv6 address 2001::1/128

Inter-AS xconnect Issue

In this example we will configure xconnect between two PE routers (R2 and R5) which are located in different ASs in order to achieve connectivity

Configuration

R1

R1#sh run int s1/0
interface Serial1/0
ip address 192.1.16.1 255.255.255.0
no keepalive

MSP Example #1 Issue

In the above topology we are going to experience several features and implementations
  • ISIS Level-2 inside the core
  • BGP as PE-CE routing protocol
  • RIPv2 as PE-CE routing protocol (CsC)
  • MPLS Traffic Engineering inside the core
  IOS XR will be part of the topology and this is the main goal of this article as...

MPLS L3VPN Internet Access

Posted by MSSK , 19 May 2013 - - - - - - · 2,934 views

MPLS L3VPN Internet Access Issue

In the above topology we have two VRFs, MSSK which connects R1 and R5 to the service provider backbone, and VRF ABC which connects R7 to the service provider core
The aim is to enable these customers to gain internet access which is represented by R8 loopback 0 interface, R8 is located in AS#1
R3 will be VPNV4 router reflector for the...

Carrier supporting Carrier (CsC) Elements

In this example we will configure Carrier supporting Carrier (CsC)
We have two autonomous systems, AS 100 and 200
Our service providers PEs are R3 and R4 which establishes VPNv4 sessions with R2 and R1, which by in turn establishes VPNv4 sessions between themselves
Our customers are R5, R6 and R9 which in turn will provide R8, R7 and...

Multicast VPN with static-rp Issue

In this example we will examine Multicast VPN with MPLS implemented using static rp for multicast information deleivery
Our CEs in this example are R1 and R5
Our PEs are R2 and R4, and R3 is the P

We will run OSPF as the IGP inside the MPLS backbone

Configuration

R1#sh run int f1/0
