RIP, OSPF, and EIGRP are IGPs. • Exterior gateway protocol (EGP). • A routing protocol operating between different AS. • BGP is an interdomain routing protocol .
Acks are always sent using a unicast address and contain a non-zero acknowledgment number. Updates are used to convey reachability of destinations. When a new neighbor is discovered, update packets are sent so the neighbor can build up its topology table.
In this case, update packets are unicast.
In other cases, such as a link cost change, updates are multicast. Updates are always transmitted reliably. Queries and replies are sent when destinations go into Active state. Queries are always multicast unless they are sent in response to a received query.

In this case, it is unicast back to the successor that originated the query. Replies are always sent in response to queries to indicate to the originator that it does not need to go into Active state because it has feasible successors. Replies are unicast to the originator of the query. Both queries and replies are transmitted reliably. Request packets are used to get specific information from one or more neighbors. Request packets are used in route server applications.
They can be multicast or unicast. Requests are transmitted unreliably.
External routes are ones that have been learned by another routing protocol or reside in the routing table as static routes. These routes are tagged individually with the identity of their origination. The AS number where the destination resides.
A configurable administrator tag. Protocol ID of the external protocol. The metric from the external protocol. Bit flags for default routing. As an example, suppose there is an AS with three border routers. A border router is one that runs more than one routing protocol.
The router-id is set to BR1. BR2, then, has enough information to determine the AS entry point for the route, the original routing protocol used, and the metric.
Further, the network administrator could assign tag values to specific destinations when redistributing the route. A configurable administrator tag. Protocol ID of the external protocol.

Using EIGRP route tagging can give a network administrator flexible policy controls and help customize routing. Route tagging is particularly useful in transit ASes where EIGRP would typically interact with an inter-domain routing protocol that implements more global policies.
This combines for very scalable policy based routing. This is important so users can take advantage of the benefits of both protocols. Since the metrics for both protocols are directly translatable, they are easily comparable as if they were routes that originated in their own AS.
This can be changed with a configuration command that does not require the routing processes to restart. The example focuses on destination N only.
Each node shows its cost to N in hops.

The arrows show the node's successor. So, for example, C uses A to reach N and the cost is 2. If the link between A and B fails, B sends a query informing its neighbors that it has lost its feasible successor. D receives the query and determines if it has any other feasible successors. If it does not, it has to start a route computation and enter the active state.
However in this case, C is a feasible successor because its cost 2 is less than than D's current cost 3 to destination N. D can switch to C as its successor. Note A and C did not participate because they were unaffected by the change.
Now let's cause a route computation to occur.
In this scenario, let's say the link between A and C fails. C determines that it has lost its successor and has no other feasible successors.When they get to area 0 they transform into LSA type 5. The arrows show the node's successor.
The router-id is set to BR1. The metric from the external protocol.
You will learn all the secrets about HSRP, gateway redundancy and more. D replies because its successor has not changed.
This combines for very scalable policy based routing. D receives the query and determines if it has any other feasible successors.
