Dynamic Multipoint Virtual Networks (DMVPN)

DMVPN is a Hub-and-Spoke topology and the main tool to create VPNs is combination of mGRE. The registration process can be conducted via Static or Dynamic. click here for all the theories about DMVPN and MPLS.

2.What is MPLS Label distributing protocol (LDP) ? How LDP works?

3.how to configure MPLS LDP Peering ?

4.What is MPLS L3 VPN ? How to configure?

5.How to configure MPLS L3 VPN with RIPv2 ?

What is Classification and marking? What is IP Precedence and DSCP Values? What is AF and EF?

By Edgar C Francis Internetworks
  Classification and Marking Classification and marking are the processes of identifying the priority of each packet. This is the first step of QOS control and should be done near the source hosts. Classification is the process of identifying and categorising traffic into classes, typically based upon incoming interface IP precedence, DSCP Source or Destination address. Application classification is the most fundamental QOS building block. Without classification, all packets are treated the same.   The table lists the criteria of classification                                  Marking  Marking is the QOS feature component that colours a packet so it can be identified and distinguished from other packets in QOS treatment. Commonly used markers: link-layer: COS (ISL, 802.1q), MPLS EXP bits,...

OSPF Tunnels Vs Virtual-links

By Edgar C Francis Internetworks
OSPF VIRTUAL LINKS  An Open Shortest Path First (OSPF) autonomous system has all areas physically connected to the backbone area (Area 0). In some cases, if this is not possible, we can use a virtual link to connect to the backbone (Area 0) through a non-backbone area. We can also use the virtual links to connect two parts of a partitioned backbone (Area 0) through a non-backbone area. The area through which we configure the virtual link, known as a transit area, must have full routing information. Remember, the transit area cannot be a stub area. Virtual link must be configuring both sides with the same area ID and the corresponding virtual link OSPF neighbor router ID. Show IP OSPF neighbors command give you the router ID information. OSPF Transit Area from Tunnel When configuring OSPF with tunnel interfaces as transit areas, there are several important considerations to ensure proper routing functionality. Here's what you need to know: Key Concepts Transit Area : In OS...

What is of NBAR (network- based application recognition),classification QOS How to configure NBAR?

By Edgar C Francis Internetworks
 When we implement Quality of Service (QoS ) the first step is classification, by default our router does not care about what kind of IP packets it is. Our router just looks at the routing table to find the correct destination IP address and forwards. When we configure QoS technologies like queuing, policing, or shaping before doing first we have to identify what kind of traffic is running on our routers so we can figure out what kind of application it belongs to. This is classification. What is Quality of Service (QOS)? What is Modular Quality of service CLI (MQC)? What is Classification and marking? What are IP Precedence and DSCP Values? What is AF and EF?     Once we identify our traffic (classify). Now we can mark and apply QoS policy to it. There are a few methods on IOS routers for classification: Header inspection It is a simple classification method and it works really good but has some disadvantages. Let’s say we configure our router all th...
