Name resolution for IPv6 addresses can be static or dynamic. Just as with IPv4, resolution of static names to IPv6 addresses can be manually configured in the host configuration file. […]
IPv6 Address-Assignment Strategies – Internet Protocol Version 6 (IPv6) Design
Assignment of IPv6 addresses to a host can occur statically or dynamically. Static IPv6 address assignment involves manual configuration on the host’s configuration files. Dynamic IPv6 address assignment can be […]
Whole IPv4 Address Linked to IPv6 – Internet Protocol Version 6 (IPv6) Design
Another method of IPv6 address allocation is to link a whole IPv4 address to the lowest significant bits of the IPv6 address. Table 2-11 shows an example using the same […]
IPv6 over IPv4 Tunneling Strategy – Internet Protocol Version 6 (IPv6) Design
In the IPv6 over IPv4 tunneling migration strategy, isolated IPv6-only networks are connected using IPv4 tunnels. With overlay tunnels, IPv6 packets are encapsulated within IPv4 packets so that they are […]
6RD Tunnels – Internet Protocol Version 6 (IPv6) Design
IPv6 Rapid Deployment (6RD) tunnels are an extension of 6to4 and allow a service provider to provide unicast IPv6 service to customers over its IPv4 network by using encapsulation of […]
IPv6 Deployment Models – Internet Protocol Version 6 (IPv6) Design
Deployment of IPv6 can be done in one of the following models: Dual-Stack Model In the dual-stack model, devices and the network routers and switches all run both IPv4 and […]
IPv6 Deployment Model Comparison – Internet Protocol Version 6 (IPv6) Design
Table 2-13 summarizes the advantages and disadvantages of the IPv6 deployment models. Table 2-13 IPv6 Deployment Model Comparison IPv6 Deployment Model Advantages Disadvantages Dual-stack model Tunneling not required. Network […]
Routing Protocol Characteristics – Routing Protocol Characteristics, EIGRP, and IS-IS
This section discusses the different types and characteristics of routing protocols. Routing protocols have the following characteristics: This section covers the default administrative distances assigned to routes learned from each […]
Interior Versus Exterior Routing Protocols – Routing Protocol Characteristics, EIGRP, and IS-IS
Routing protocols can be categorized as interior gateway protocols (IGPs) or exterior gateway protocols (EGPs). IGPs are meant for routing within an organization’s administrative domain (in other words, the organization’s […]
Poison Reverse – Routing Protocol Characteristics, EIGRP, and IS-IS
Poison reverse is a route update sent out an interface with an infinite metric for routes learned (received) from the same interface. Poison reverse simply indicates that the learned route […]
