Hi Group,
I have done a few Mock Labs to prepare my 1st $1400 rack rental in San Jose
early April. And I just recieved the report for my mock lab yesterday. I have
some questions really need your help.
1. I heard that the general rule in the lab is full ip reachability. So if
only some routers in the lab are running BGP. And I did not bring routes
advertised by BGP routers and/or BB routers or maybe I did not redistribute a
loopback interface which is not included in any routing prortocol. Am I
automatically failed the lab even I get 80% or over? Or it is not possible to
get 80% or more?
2. I would like some clarification on tasks I lost points in the mock lab. I
would really appreciate your input. The question says:
. Network administrators of R6 have been noticing output drops accumulating on
the Frame Relay link to BBI. In order to prevent this
type of tail drop configure R6 to randomly drop packets before congestion
happens on the Serial interface's output queue.
. In order to ensure that critical traffic transiting your network gets the
best service possible configure R6 so that critical traffic will not be
dropped unless there are 50 packets in the output queue.
. If there are 70 critical packets in the output queue R6 should randomly drop
2 out of every 16 of these packets.
. In the case that there are more than 70 critical packets in the output
queue, they should all be dropped.
My answer to the task is :
interface Serial0/0
ip address 54.9.1.6 255.255.255.0
encapsulation frame-relay
ip summary-address rip 129.9.0.0 255.255.128.0
random-detect
random-detect precedence 5 50 70 8
random-detect precedence 6 50 70 8 <------------------- EXTRA CONFIG
random-detect precedence 7 50 70 8 <------------------- EXTRA CONFIG
frame-relay map ip 54.9.1.254 101 broadcast
no frame-relay inverse-arp
My question is : Do I get points for this question with the extra lines of
config indicated?
3. Task says:
. Configure SWI and SW4 in such a way that R5 E0/0 and SW2 Fa0/20 appear
directly connected via CDP.
. If an additional VLAN is needed use VLAN 100.
Layer 1 connection: R5(e0/0)====SW1====SW4=====(Fa0/20)SW2
"Diagram here http://docs.google.com/Doc?id=dgsxsjvv_44htgh39dp"
I successfully configured a layer 2 tunnel. So that R5 and SW2 see each other
as neighbor according to CDP.
Now, SW2 was pre-congifured with the ip address on interface vlan 58. I was
trying to put the ip address on the Fa0/20 of SW2. SW2 complained about
duplicate ip address. I then I looked the lab rule as shown below:
Lab Do's and Don'ts:
. Do not change or add any IP addresses from the initial configuration unless
otherwise specified
. Do not change any interface encapsulations unless otherwise specified
. Do not change the console, AUX or VTY passwords or access methods unless
otherwise specified
. Do not use any static routes, default routes, default networks, or policy
routing unless otherwise specified
. Save your configurations often
However, I lost points on this task because "IP address should've been
configured on SW2's Fa0/20 interface as per diagram, not on Vlan58"
Is it a fair game? Did I miss something. Due to points lost on this task, I
also lost points on other task relied on this task. The reason is "EIGRP
hellos should've been sent out SW2's Fa0/20 interface, not Vlan58"
Please help,
Lui
