BGP is a distance vector or link state protocol?
path vector?
BGP creates and maintains connections between peers, using ___ port ___
TCP 179
The connection is maintained by ....
periodic keepalives.
Any change in the network
results in a _____
triggered update.
It is possible to manipulate the traffic flow by using _________
Four different message types are used in BGP:
■ Open messages —Used to establish connections with peers.
■ Keepalives —Sent periodically between peers to maintain connections and verify paths
■ Update messages —Contain paths to destination networks and the path attributes
■ Notification—Used to inform the receiving router of errors that cause the connection to be closed.
BGP will propagate
1) the prefix and the prefix mask together
2) only prefix
3) only prefix mask
1) the prefix and the prefix mask together
What is the hop-by-hop paradigm?
This paradigm is the capability to influence which router will be the next-hop router, potentially dictating it at every router and thus influencing the entire path of the traffic, hop by hop.
Traffic can be directed on either the ____________ or both the
source address
source and destination addresses
Policy-based routing does not affect the destination of the packet. It affects the path used to get to the destination.

True / False
Policy-based routing does not allow traffic sent into another autonomous system to take a different path from the one that would have been chosen by that autonomous system.

True / False
It is possible to influence how traffic will be routed within that autonomous system.

It is possible to influence only how traffic will get to a neighboring autonomous system, not how it will be routed within that autonomous system.
The Four Categories of Attributes are:
Well-known (mandatory / discretionary)
Optional (Transitive / Non-transitive)
