| | Border Gateway Protocol (BGP) |
 | | When BGP is used between autonomous systems (AS), the protocol is referred to as External BGP (EBGP). | | | BGP is a very robust and scalable routing protocol, as evidenced by the fact that BGP is the routing protocol employed on the Internet. | | | BGP neighbors exchange full routing information when the TCP connection between neighbors is first established. |

| | IP Routing: Chapter 4: Enhanced Interior Gateway Routing Protocol (EIGRP) |
| | Thus, if a route was learned from RIP with a hop count of 3 and redistributed into EIGRP, the originating router field would contain the address of the RIP router, the originating AS field would be empty, the external protocol metric would be 3, and the external protocol ID would be 0x04. | | | This is similar to RIP and IGRP and is a prudent way for a routing protocol to reduce the number of routes that are propagated between routers. | | | If this route were to become SIA, the network engineer should trace the path of the queries to see which router has been queried, has no outstanding queries itself, and yet is taking a long time to answer. |

| | Cisco - Enhanced Interior Gateway Routing Protocol |
| | Enhanced Interior Gateway Routing Protocol (EIGRP) is an interior gateway protocol suited for many different topologies and media. | | | External Protocol shows the protocol this route came from (if there is one). | | | A typical distance vector protocol saves the following information when computing the best path to a destination: the distance (total metric or distance, such as hop count) and the vector (the next hop). |

| | The File Transfer Protocol (FTP) and Your Firewall / Network Address Translation (NAT) Router / Load Balancing Router |
| | Solution 2: The network administrator of the server network can consult the load balancing router vendor's documentation to see if FTP connections can be handled automatically so that the PASV reply is dynamically rewritten to contain the external IP address of the load balancer. | | | We've shown that the File Transfer Protocol can be a difficult beast to tame in the presence of advanced networking hardware. | | | The external IP address of the load balancer could be used as the preferred address, but having each slave server have its own external IP address would allow PASV data connections to connect directly to the slave server without requiring traffic from slaves to pass through the load balancer. |

| | Interior Gateway Protocols |
| | An IGP (Interior Gateway Protocol) is a protocol for exchanging routing information between gateways (hosts with routers) within an autonomous network (for example, a system of corporate local area networks). | | | External routes are learned by another routing protocol or reside in the routing table as static routes. | | | After a router is assured that its interfaces are functioning, it uses the OSPF Hello protocol to acquire neighbors, which are routers with interfaces to a common network. |

| | Routers/Switches: Two routers balancing |
| | So I wasn't trying to balance traffic from the internal router to the two external routers, but to balance the outbound traffic once it got to the pool. | | | Or you could stick a 2600 or something between your internal router and the two externals and balance on it. | | | The idea wasn't to balance the routers, but to balance the outbound traffic across the two circuits to better utilize bandwidth while using a single IP for two routers. |

| | For external networks, neither of these protocols work well enough to support a significant number of networks, and other protocols (such as the Border Gateway Protocol) are more common for those environments. | | | If this involves sending the datagram through another intermediary system, then that system also makes routing decisions according to the current condition of the network, forwarding the data on until it arrives at the destination system, as specified in the datagram's header. | | | If the original datagram is 4,464 bytes long, then at least 20 bytes of that datagram are being used to store header information, meaning that the data portion is 4,444 bytes long. |

| | routed(1Mtcp) |
| | When a TCP connection suffers a timeout, the kernel tells routed, which deletes all redirected routes through the gateway involved, advances the age of all RIP routes through the gateway to allow an alternate to be chosen, and advances the age of any relevant Router Discovery Protocol default routes. | | | Routes through passive gateways are installed in the kernel's routing tables once upon startup and are not included in transmitted RIP responses. | | | The function of external entries is to indicate that another routing process will install such a route if necessary, and that alternate routes to that destination should not be installed by routed. |
