Definitions

1. Source Routing is a type of routing used by bridges.
2. Source routing was designed to allow individuals the ability to specify the route that a packet should take through a network. (Web site)
3. Source routing is useful when the default route that a connection will take fails or is suboptimal for some reason, or for network diagnostic purposes. (Web site)
4. Source routing is almost obsolete now, and the majority of routers filter out source routed packets.
5. Source routing is only supported for Token Ring networks. (Web site)

Routing Paradigm

1. Note that some policies cannot be supported by the "hop-by-hop" routing paradigm and thus require techniques such as source routing to enforce. (Web site)

Source Routing Bit

1. The identification within each packet is done by examining the routing field and source routing bit within the MAC layer header. (Web site)

Medium Access Control Sublayer

1. In Token Ring environments, source routing at the medium access control sublayer is a major routing method.

Source Routing Identifier

1. On the other hand, if the source routing identifier does exist, source routing is used, block 78. (Web site)

2. Next-generation APPN that replaces the label-swapping routing algorithm with source routing.

Ability

1. The ability to use loose source routing to see the reverse route could be pretty handy.

Routing Information

1. This bridge looks for the routing information inside each packet associated with source routing. (Web site)

Types

1. Some types of source routing (for example, Token Ring) are handled by the medium access control sublayer.

Reason

Information

1. When the list of hosts is present, it is source routing information and indicates that the mail must be relayed to the first host on the list. (Web site)
2. If the source routing identifier is a logical 1, then the packet of information has a source routing field and uses the source routing method. (Web site)
3. For more information about source routing, see the ip-param.txt document.

Address

1. However, with this form of source routing the PDU may take any path necessary to arrive at the next address in the list.
2. Note: If an address uses source routing, it can send and receive traffic through the firewall router. (Web site)

Static Routing

1. It clearly defines commonly used terminology such as static routing, store-and-forward routing, source routing and others. (Web site)

Unix Machines

1. Still, there is substantial use of Linux and Unix machines, running open source routing code, for routing research and selected other applications.

Network

1. A network using a fiber data distributed interface (FDDI) for network communications cannot use NBF for source routing. (Web site)

Frame Type

1. IPX IPX test Examines the network's IPX configuration, including Frame Type, Network ID, RouterMTU and whether packet burst or source routing are enabled.

Options

1. The types of options supported by these fields typically include source routing, priority and security-specific information. (Web site)
2. We've described the following IP options: record route (Section 7.3), time-stamp (Section 7.4), strict and loose source routing (Section 8.5).

Option

1. The option is specified by including source routing information in the Target structure.
2. An aspect of this invention is the use of an IP feature known as a Loose Source Record Routing, or Loose Source Routing (LSR) option. (Web site)

Firewall

1. If a firewall or gateway reverses the source routing information when sending packets back, you can sniff traffic at one of the hops you defined. (Web site)

Datagram

1. Section 7.4), loose source routing (specifying a list of IP addresses that must be traversed by the datagram.
2. Triggers on receipt of an IP datagram in which the IP option list for the datagram includes option 2 (Strict Source Routing).

Bridges

1. The source routing bridges add additional routing information to the frame and send it to all other rings to which the bridge is connected. (Web site)
2. Transparent bridges are used for Ethernet, whereas source routing bridges are used for token ring networks. (Web site)

Bridge

1. Another type of bridge is called a source routing bridge. (Web site)
2. In addition, the bridge provides source routing over multiple wide area channels to those nodes which use source routing. (Web site)
3. The second routing method is source routing, in which a bridge or brouter looks at the source routing field of the datagram. (Web site)

Protocol

1. The LAN numbers are used by the bridges to identify LANs in a source routing protocol. (Web site)
2. However, we opt against further discussion of such a protocol because there is less to gain by using source routing without also using a link state scheme. (Web site)

2. A source routing attack can be defeated by simply discarding all packets that contain the source route option. (Web site)

Spoofing

1. SSH protects a network from attacks such as IP spoofing, IP source routing, and DNS spoofing.
2. Disabling source routing at all routers can also help prevent spoofing.
3. It means that the firewall examines the states of all internet connections, looking for the telltale signs of hacking, such as source routing or IP spoofing. (Web site)

2. Bridge Number A 4 bit number identifying the bridge on the token ring, as defined in the IEEE 802.5 Source Routing Specification. (Web site)
3. From a Token Ring LAN, PIR looks like a Source Routing bridge; in an Ethernet environment, PIR appears as a Transparent bridge.

Router

1. With strict source routing, the next intermediate destination must be directly reachable (it must be a neighbor on an interface of the router).
2. You tried to use source routing, but the router is configured to block source-routed packets.
3. Note: Disabling source routing at the router does not protect you from this attack, but it is still good security practice to follow. (Web site)

Route

1. In a source routing attack, the source station specifies the route that a packet should take as it crosses the Internet. (Web site)
2. Consequently, it is possible for a source routing domain to compute a route that is not operational at route installation time. (Web site)

Routing

1. NetBEUI uses Token Ring source routing as its only method of routing.
2. It can use Token Ring source routing as its only method of routing. (Web site)
3. NBF can provide a simple form of routing known as Token Ring source routing, and it can only be implemented on Token Ring networks. (Web site)

Packet

1. To accomplish source routing, the routed packets contain the address of each device the packet will traverse.
2. It then decides which routing service to provide to this packet, namely, source routing or transparent routing. (Web site)
3. Loose source routing allows the packet to use any number of intermediate gateways to reach the next address in the route. (Web site)

Dsr

1. To avoid using source routing, DSR optionally defines a flow id option that allows packets to be forwarded on a hop-by-hop basis.
2. DSR uses source routing which is regarded as one of the main feature of this scheme.
3. DSR is a source routing protocol where the route is in each packet. (Web site)

Source Routing

1. IP source routing The practice of specifying the list of router interfaces corresponding to the path through an IP internetwork that a packet must travel.
2. By default, the stack transmits ARP queries without source routing first and retries with source routing enabled if no reply is received.
3. For a firewall, source routing is noteworthy, since an attacker can generate traffic claiming to be from a system "inside" the firewall.
