accross the 'Cost' metric as being 10^8/bandwidth bps

My question is : Using the above equation 10 Meg

Duncan,
The area field is 32 bits. Converting 0.0.0.1 to

believe it would therefore correspond to decimal area

James,
I wouldn't have expected that, the likelihood of
the loopback process crashing without the router
crashing as well is miniscule. It looks more likely
that Cisco have put it in for completeness.
I would guess that the extra CPU overhead is also very
small as well.

The passive-interface command behaves differently for

Hi,
I'm hearing positive vibes about a training course
run by Martin Shortland in the U.K for CCIE Lab prep.
A 12 day course running at around £3900 + VAT.
Has anyone got any comments or got a link for this
course ?
PS : Also heard negative comments about NETGUN.
Regards,
Phil.

Andrew,
What IOS version are you running on ?
Do you have any other Routers on any other Token Ring
segments ?
I believe that major surgery was implemented in IOS
11.3 for EIGRP not sure how that would effect Token
Ring though.
Have you analysed the Token Ring Segment for errors
e.g beacon
Hi,
I have 2 Routers connected via 3 Fa/Eth segments.
The segs are configured in an HSRP arrangement.
I pinged 224.0.0.2 from one Router and got 3 replies
that I expected from the other router PLUS one that I
dont understand.
This phantom device that replied cannot be telneted
nor tracert' but
entry is there, trace down

Hi group,
I've got a 7507 Router with a dodgy VIP card.
I've noticed that the running config has changed since
the fault on the card developed.
This would suggest that this part of the config
actually sits on the VIP card and not in Normal RAM.
The NVRAM config still reflects what the true co
Thanx for the input,
Unfortunately the configs are 120 miles away. I only
really get a chance to play at the weekends when I'm
back home.
But there is really nothing fancy in the configs.
When I cut the link TOP->RIGHT I waited for the route
to get flushed out the table i.e 280 secs (I think)

Here they are,
I'm on leave for 2 weeks, so I have to shut down

Hi groupies !!!
I just happened upon this' whilst trying to rest
my brain from BGP.
A RIP II update sends a network mask out onto the
wire for every network the router is advertising.
Why didn't the designers just code the network
mask as a 6 bit field which could represent any mas
Sorry Howard, I appear to have deleted the original
thread.
Howard,
You mentioned that computing the network mask from
a 6 bit field would be detremental causing unnecessary
CPU overhead, however, this CPU overhead would only be
in nano-seconds compared to the serialisation delay
i.e getting
David,
I don't know enough about Decnet to help you but be
wary when sniffing that the MAC address that the
sniffer picks up is different than what you would
expect. Decnet uses an algorithm to convert the "real"
MAC address to another.
Also I seem to remember a lot of munticasting takes
plac
I took the support exam in Feb 2001 UK. There was
appletalk on, in the form of sniffer output, what is
this frame ? etc. I had about 10 of these type of
questions, which is good if you know your sniffer.
Regards,
Phil.
