1:

Does BGP have its own transport mechanism to ensure the guarantee of BGP updates?

  1. BGP has its own transport mechanism to deliver BGP packets to its neighbors.

  2. UDP is a preferred method because BGP neighbors are in most cases directly connected and the loss of packets is unlikely .

  3. BGP uses TCP as its transport mechanism.

2:

Assuming no Route-Reflection or Confederations are used, what problems might occur if IBGP neighbors are not fully meshed?

  1. An IBGP update will not be propagated to BGP routers in the AS because the IBGP learned update is not announced to other IBGP neighbors.

  2. Everything will run fine.

  3. Only external BGP neighbors won't receive the BGP updates.

3:

What BGP technique is used to penalize flapping of BGP routes in some other AS?

  1. Route-Reflection

  2. Dampening

  3. Peer groups

4:

The BGP process can exchange updates with its neighbors after passing which neighbor state?

  1. Established

  2. OpenSent

  3. Active

5:

Which of the following techniques are used in solving the IBGP full mesh requirement?

  1. Dampening

  2. Aggregation

  3. Route Reflection and Confederation
