To ensure that all routers are directly connected.

To ensure that all routers run iBGP inside a transit AS.

To maximize control plane scalability.

Router R1must have at least one BGP session to each of routers R1x and R2x.

Routers R1x and R2x must have at least one BGP session between them.

Routers R1x as well as routers R2x must be fully meshed.

All routers with which it has a BGP session.

All routers with which it has a BGP session, except the router it received the update from, which is router B.

All routers with which it has a BGP session, except the router it received the update from, which is router C.

All routers with which it has a BGP session, except the router it received the update from, which is router D.

Path-ID is a four-octet identifier pre-pended to the NLRI field of a BGP update.

Path-ID uniquely identifies each path advertised to a neighbor.

A BGP speaker that re-advertises a route must generate its own Path-ID.

Originator_ID of RR1; and Cluster_List of 10.16.10.1.

Originator_ID of RX; and Cluster_List of 10.16.10.1.

Originator_ID of RR1; and the Cluster_List is not set.

Prefix 192.160.0.0/13 longer.

The session between router C and router B.

The session between router D and router B.

Router B will learn the prefix over all of the sessions, then it will choose the best route.

ISP 1 is downstream from ISP 3 and is expected to push more traffic toward ISP 3 than it pulls from it.

ISP 3 is downstream from ISP 1 and is expected to push more traffic toward ISP 1 than it pulls from it.

ISP 3 is downstream from ISP1 and is expected to pull more traffic from ISP 1 than it pushes toward it.

Router RA prefers the update received from router RR1.

Router RA prefers the update received from router RR2.

Router RA accepts both updates and flags them as used.

Route reflectors require "n" iBGP sessions, where "n" is the number of BGP routers in the AS.

Route reflectors disable iBGP split horizon for all iBGP peers in the AS.

Route reflectors do not work in conjunction with confederations.

ISP 1 and ISP 2 have a public transit relationship, while ISP 3 and ISP 4 have a private transit relationship.

ISP 1 and ISP 2 have a private transit relationship, while ISP 3 and ISP 4 have a public transit relationship.

ISP 1 and ISP 2 have a private peering relationship, while ISP 3 and ISP 4 have a public peering relationship.

BGP Fast Reroute is triggered by IGP events.

The backup path is pre-computed and installed in the FIB.

BGP Fast Reroute is independent of number of affected prefixes.

An update message is used. Only a single prefix can be withdrawn at a time.

A withdraw message is used. Only a single prefix can be withdrawn at a time.

A withdraw message is used. Multiple prefixes can be withdrawn at a time.

TTL is a well-known mandatory BGP attribute.

The default TTL value of an iBGP message can be modified using the multihop command.

The default TTL value of an eBGP message can be modified using the "ttl-security" command.
