Q: For minimal configuration, are you looking for route reflectors or peer groups?
A: Where appropriate, both; certain peering might only be possible with route reflectors anyway.
Q: If I cannot use the network command, can I redistribute my IGP selectively?
A: No.
Q: Can I just set up an aggregate address to extend the network 2.2.2.0/28?
A: If this maintains the original attributes, yes, but you might care to check that it does.
Q: As soon as I set up the new interfaces and advertise them within BGP on R2 and R1, will R8 see both of these automatically?
A: Yes, it will unless you configure a specific BGP feature on R1.
Q: Do you want network 5.5.5.0 to be advertised into AS1 but not AS10 or AS12?
A: No, the question does not request this.
Q: I can stop network 5.5.5.0 from entering AS10 and AS12 by using a filter-list outbound on R6; will I score half marks by doing this?
A: No, the question specifically states you must only configure R5. You have a method available to you that will effectively inform R6 not to advertise this particular network.
Q: If the VLAN flaps, will the session be maintained for a small amount of time anyway?
A: No, two external neighbors peering on a connected interface will drop the session immediately.
Q: Do you want me to set up an access list between each BGP peer to only allow TCP port 179 between them so only the correct peers communicate?
A: No, use a BGP feature to make peering secure.
Q: Is it sufficient to use password authentication between BGP peers?
A: Yes.
Q: I seem to have a connectivity problem in AS10 from R8 to networks originated within AS1; should I be able to reach these networks from R8?
A: Yes, you should be able to communicate between all BGP networks from all routers.
Q: I have performed some debugging and found that R8 is attempting to send my ICMP test traffic to 172.16.0.1 for networks in AS1. I understood this network was not to be redistributed; is this correct?
A: Yes, network 172.16.0.0/16 should not be redistributed; use a BGP feature within AS10 to manipulate the BGP routing table on R8.
