Help on Case study CCNA4

Iam making the case study for CCNA4
But iam having difficulitys on the part where you have to create a framerelay.
Iam using packettracer 5.0, and tryed to make a cloud.

alltough the course and teacher said i need to use a router to simulate the framerelay

So my questions are:
1. How do i create framerelay with Packettracer 5.0
2. Does anybody have a techguide that explains how framerelay work

Did you download the labs that went with PT5? There is are 2 frame relay labs along with some others.

sorry for replaying this late, was on work... no havent seen the labs, i will check them out later...

i need some kind of techguide with an explanation how framerelay works....

thnx for replaying

I'm also having problems setting up frame relay in Packet Tracer 5. I've got no problem setting up one VC but any more than that, the 'cloud' throws an error at me.

clintregeling

going to ask my teacher tomorrow, maybe he knows it...

if i get an explanation i will post it here

wbosher

Cheers mate, appreciate it.

clintregeling

Well teacher was no help at all,

but i seem to got it working now, except the following

i have 4 routers

router 1

router 2

router 3

framerelaycloud ---Router 4
0000

00000

000000

0000000

0000000

connection between all routers are ok

ping router 1 to 2 and 3 are ok
ping router 2 to 1,2,4 are ok
ping router 3 to 4,1,2 are ok
ping router 4 to 3 and 2 are ok

but router1 ping to 4 fails
and router 4 to router 1 fails

any ideas???

scheistermeister

Check the routing tables, probably have split horizon at work somewhere.

clintregeling

iam using pt5 can it be because of the cloud from my framerelay?

clintregeling

removed cloud, and still same problem... maybe my redistrubution from ospf to rip??

clintregeling

Ok i found my problem, it was my redistribution...

what i did to solve it, i gave the router wich redistrubuted ospf into rip a default route
....

now its working...

thnx for help this far....

I'm having the exact same problem. How exactly did you put the default route?

Ok here's my problem:

It's the same thing (It's the CCNA4 case study v3.1), but here's my configuration:

Every router except for Galway (router 4) has OSPF. Router 4 has RIP version 2, with its serial subnet, and its LAN subnet. in Cork (Router 3) I'm using OSPF, but also RIP version 2 for the "172.16.0.0" subnet, which is the summarized address for everything. And I'm doing the "redistribute rip subnets" under router ospf 1.

Now, when I input "show ip route" in Galway, I get this:

R 10.0.0.0/8 [120/2] via 172.16.7.253, 00:00:02, Serial0/0
172.16.0.0/16 is variably subnetted, 5 subnets, 2 masks
C 172.16.0.0/22 is directly connected, FastEthernet0/0
R 172.16.7.248/30 [120/1] via 172.16.7.253, 00:00:02, Serial0/0
C 172.16.7.252/30 is directly connected, Serial0/0
R 172.16.8.0/22 [120/1] via 172.16.7.253, 00:00:02, Serial0/0

There's only one address missing there, which should be the 172.16.7.244/30 subnet, but it's not learning it.

In the cork router, I get this:

Cork#show ip rip database
172.16.0.0/22
[1] via 172.16.7.254, 00:00:21, Serial0/0
172.16.7.248/30 directly connected, Serial0/1
172.16.7.252/30 directly connected, Serial0/0
172.16.8.0/22 directly connected, FastEthernet0/0

which shows that the .244 address isn't being transmitted through RIP to the Galway router, I'm guessing, right? So I'm thinking that's the problem, but I can't figure out why it's happening.

Is it because I need to activate RIP in the Belfast router too? Would be weird, because it's never specified in the instructions.

Also, if I input show ip ospf database in Cork:
OSPF Router with ID (172.16.8.1) (Process ID 1)

Router Link States (Area 0)

Link ID ADV Router Age Seq# Checksum Link count
172.16.7.249 172.16.7.249 777 0x80000005 0x00c065 5
172.16.7.245 172.16.7.245 777 0x80000002 0x00e93b 2
172.16.8.1 172.16.8.1 565 0x80000005 0x0062bb 4

Type-5 AS External Link States
Link ID ADV Router Age Seq# Checksum Tag
172.16.0.0 172.16.8.1 565 0x80000001 0x0064dc 0

I don't see the 10.0.0.0 address that's in router Belfast, which is weird because that one should be appearing.

Ok I found in another post that doing:

router rip
version 2
redistribute ospf 1 metric 1

would work, and it did!

Now the only thing I'm not clear about is what the "Metric" in there means exactly. It went from 1-16, so I'm guessing it's the hop number, but how would it affect if I put "2" for example?

jcd29

any idea?
