This routing header was designed to support the same use cases as the IPv4 header options. As there were several significant attacks against this routing header, its utilisation was deprecated. [6] A more secure form of source routing was being developed within the IETF as of 2017 to support the IPv6 version of segment routing. [7]

On a network with a single edge router, it is possible to implement source-specific routing by manual manipulation of routing tables. [6] With multiple routers, explicit support for source-specific routing is required in the routing protocol. As of early 2016, there are two routing protocols that implement support for source-specific routing:
Loose Source Routing is an IP option which can be used for address translation. LSR is also used to implement mobility in IP networks. [3] Loose source routing uses a source routing option in IP to record the set of routers a packet must visit. The destination of the packet is replaced with the next router the packet must visit.
Rules are encoded in a routing table that contains entries for all interfaces and their connected networks. If no rule satisfies the requirements for a network packet, it is forwarded to a default route. Routing tables are maintained either manually by a network administrator, or updated dynamically by a routing protocol.
Support for XORP on Microsoft Windows was recently re-added to the development tree. XORP is available for download as a Live CD or as source code via the project's homepage. The software suite was selected commercially as the routing platform for the Vyatta line of products in its early releases, but later has been replaced with quagga. [5]
Messages are often delivered right way though very rarely there may be a delay in transit. This is usually due to problems on the mail server, heavy internet traffic, or routing problems. Unfortunately, other than waiting, you won't be able to determine if the message is delayed or undeliverable.
Routing protocols, according to the OSI routing framework, are layer management protocols for the network layer, regardless of their transport mechanism: IS-IS runs on the data link layer (Layer 2) Open Shortest Path First (OSPF) is encapsulated in IP, but runs only on the IPv4 subnet, while the IPv6 version runs on the link using only link ...
