MPLS VPN – option C – using bgp label exchange with cisco and Junos -part 1

Leave a reply

It has been a while since I have done any labs after getting a new job. This time, I will be building a NNI option C using both Cisco IOS and Juniper MX. The reason I write this is because I do not find many resources on the internet about the inter AS connection using 2 different software at the same time. Hope this can be useful for anyone who is having the same struggle as i do.
(the AS# below are randomly picked!!)

Based on the lab diagram (dont feel like copping it up), as the internal VPN service is already running and the intra AS is running OSPF and LDP for MPLS, I will be connecting AS5052 (the green aren in middle) and AS7077 (the orange area at the bottom) together over NNIs to extend the MPLS VPN services.

MPLS VPN – routes sharing between 2 different VRFs across the MPLS network

Leave a reply

The beaut of MPLS VPN is to have multi tenants running over the same MPLS core network and each tenant are prevented to access other tenants networks. But what if the 2 different tenants want to connect to each other?
In the lab below, we have 2 different tenants and they are 1120020010 (RT:200010) in Router 12 and 1030010010 (RT:100010) in Router 03. By default, the ASAs connected to these VRFs cannot communicate since they are in 2 different VRF network. In this case, I will be using Cisco IOS and Juniper MX to let 2 different VRFs to connect together.

We could check the existing configuration and the route table in Router 03 and Router 12

Traffic Engineering – MPLS

Leave a reply

This time we will handle the basic traffic engineering within a MPLS network. This technique allows network admin to manipulate the traffic and fully utilize the subscribed bandwidth or circuits.
Traffic engineering within a MPLS network can be more accurate and convenience than in a typical TCP/IP network, because TE are happened at the MPLS level only, which would not affect the base of the whole network topology. If manipulate traffic at the IP level, everything running on top of IP level will be affected.
The network topology for this testing is listed below.

Playing with Multicast – Part 4 – NV-MVPN on Junos

2 Replies

It sure has been some times since the last multicast post. This time, we will put the lab into a higher level, and will be running the multicast on the MPLS VPN platform. Since this post is focusing on MCast only, the configuration for MPLS network will not be described with my detail. So let s dig in.

Playing with Multicast – Part 2.

1 Reply

The part 1 of multicast was simply doing the streaming within a local area network. This time, I will put my multicast lab to a level higher and put a router between the sender and receiver.
The test bed for this time will involve a simple routings. Please refer to the topology below.
To keep the multicast lab simple, it will be running on Sparse mode and using static RP instead of dynamic.
TOPOLOGY:
Mcast_topo_with_1_router
Components:
1x Ubuntus as sender
1x Windows XP as receiver.
1x Junos router Continue reading →
