CCIE Routing and Switching Practice Labs

Q: Can I configure bridging to get R1, R6, R8, and Switch1 to reply to pings?

A: No.

Q: R3 is on a different subnet; will the broadcast get blocked?

A: By default, yes; find a way of allowing it through without bridging.

Q: Can I configure mobile IP for R7?

A: Look for a less complex method of achieving connectivity.

Q: Can I put a secondary address on R6 in the same subnet as R7 and then somehow give connectivity to VLAN4?

A: No.

Q: Can I enable Local Area Mobility (LAM) in my network?

A: Yes.

Q: LAM will produce a host route, is that acceptable at this point in the lab?

A: Yes, the question does not state that there should be no host route at this point; there is an earlier reference to your IGP routes though.

Q: Surely R6 will proxy-ARP for the loopbacks on R4, R5, R6, and R8 if I enable it?

A: Proxy-ARP is enabled by default and it will not initially work.

Q: Can I change the mask on the 10.50.50.0/29 network on R7 so it becomes a /8 to then make R7 send ARP requests for the destination networks?

A: No.

Q: If I add a secondary address as network 10 with a mask of /8, is this acceptable?

A: Yes.

Q: I have added the secondary address, but I still do not have connectivity to the remote networks.

A: You need to add further configuration.

Q: My ARP table is not complete for the destination addresses; is it acceptable to add static entries on R7 for these?

A: Yes.

Q: To load share, can I just put an OSPF cost on my Frame Relay interfaces?

A: Yes.
