Let’s illustrate how to configure Dynamic NAT. At this point, if you are unfamiliar with NAT then please read this post here first. We will use the following topology to make our point… This topology above consists of a number of hosts (Host A, Host B, and Host C). The Service Provider has allocated a pool [ Read More ]

Let’s illustrate how to configure Static NAT. At this point, if you are unfamiliar with NAT then please read this post here first. We will use the following topology to make our point… Here, we have Host A which needs to connect to the web server. Host A IP address is 192.168.1.1 (Inside Local) which [ Read More ]

Both Network Address Translation (NAT) and Port Address Translation (PAT) perform similar functions with regards to remapping RFC 1918 IP address(es) to IP address(es) on an external network segment. With the proliferation of IoT and the rapid extension of IPv4 addresses, this technology has become essential with regards to conserving Private IP address Pool. In [ Read More ]

In this topic, we will talk about MPLS L3 VPN Central Services. At this point, if you are unfamiliar with MPLS then please read the first portion of this post here explaining in details how MPLS works. MPLS Central Services is also referred to as MPLS Common Services and its goal is mainly to allow distinct [ Read More ]

In this post, we will look into setting up MPLS VPN and use BGP as our routing protocol between the PE router and the CE router. We won’t go deeper into the MPLS VPN backbone configuration but just the PE-CE segment. At this point, if you are unfamiliar with MPLS VPN, please read this post here. [ Read More ]

In this post, we will look into setting up MPLS VPN and use OSPF as our routing protocol between the PE router and the CE router. We won’t go deeper into the MPLS VPN backbone configuration but just the PE-CE segment. At this point, if you are unfamiliar with MPLS VPN, please read this post here. [ Read More ]

In this post, we will look into setting up MPLS VPN and use EIGRP as our routing protocol between the PE router and the CE router. We won’t go deeper into the MPLS VPN backbone configuration but just the PE-CE segment. At this point, if you are unfamiliar with MPLS VPN, please read this post here. [ Read More ]

In this post, we will look into setting up MPLS VPN and use RIPv2 as our routing protocol between the PE router and the CE router. We won’t go deeper into the MPLS VPN backbone configuration but just the PE-CE segment. At this point, if you are unfamiliar with MPLS VPN, please read this post [ Read More ]

MPLS (Multiprotocol Label Switching) is technology which allows fast packet forwarding using “Labels” within a given network. VPN (Virtual Private Network) is then implemented to provide a connected oriented service by ensuring end-to-end reachability between non directly connected nodes. At this point, if you are unfamiliar with MPLS then please read the first portion of this [ Read More ]
