Firstly, 2 to the power of 4 is 16 (2x2x2x2).
Secondly, regarding Carl's post, would the answer be 14? I'm not sure the
subnet-zero comes into play with CIDR. I was under the impression it was
only relevant to subnetting as opposed to summarizing. Does anyone know for
sure?

Hi all,
I am using a cisco router with a frac-E1 link terminated on it (256kbps). I
am
running some Ipsec tunnels
across this link. Sometimes i have found that i/p o/p rate shows more then
256kbps using the show interface ser command.
i have seen it upto 32 bps?
Plz can somebody explain this
One of the choices in the question was 16but 14 was not a choice. Could
it be that since 14 was not a choice that 8 was the closest thing since 16
is possibly wrong because of the 0 subnet? This seems a little off the wall
to me butsometimes those cisco questions are off the wall. Dain.

Lim,
Two things regarding your post.
1. You can clear a single ARP CACHE entry using SNMP. Check this link...
http://www.cisco.com/warp/public/477/SNMP/clear_arp.shtml
2. Clearing the ARP-CACHE or REBOOTING the router will NOT allow you to
duplicate a used STATICALLY assigned IP address.
Shot in the dark here. =)
How about "clear ip nat trans"? Could you use that to clear the errant NAT
entry to "free up" that IP address?

Bob,
I would have to agree. With CIDR, in most cases you will get 16 usable
subnets and 2 unusable addresses (the network and the broadcast).
ex. 192.168.96.0 255.255.240.0
192.168.96.1 --> 192.168.111.254 all usable
192.168.96.0 network
192.168.111.255 broadcast
I could see the question possi
If the choices are either 8 or 16, I'd definitely go with 16.
192.168.0.0/20 would be (for example):
192.168.0.1 to 192.168.15.254
Which is 16 total subnets.

When using PPP callin, it occurs on the receiving device. Conceptually think
of it this way, the calling device places a call, the receiving device
receives the call, the calling device calls the initiating device back. Hope

My preference is to keep IDS on the inside of the firewall. The stuff
blocked by the firewall will be in the firewall logs (well, maybe). IDS
can be very annoying, so much that you ignore it.
I'd say that's my $0.02, but after taxes, it's not even worth that.
