# Guide 3
|
||||
|
||||
## Ex 1.5
|
||||
|
||||
|Ping from:|Ping to:|Connectivity|Packets (PC1-Switch1 link)|Packets (PC3-Switch1 link)|
|
||||
|:-------:|:------------:|:---:|:----:|:---------:|
|
||||
| PC2 | Switch1 | No | ARP | N/A |
|
||||
| PC2 | PC3 | No | ARP | N/A |
|
||||
| PC2 | 192.168.1.34 | No | ARP | N/A |
|
||||
| PC3 | Switch1 | Yes | N/A | ARP, ICMP |
|
||||
| PC3 | PC2 | No | N/A | ARP |
|
||||
| PC3 | 192.168.1.34 | No | N/A | ARP |
|
||||
| Switch1 | PC3 | Yes | N/A | ICMP |
|
||||
| Switch1 | 192.168.1.34 | No | N/A | ARP |
|
||||
|
||||
PCs from different vlans are unable to communicate since the switch is unable to make the connection between vlans. Neither PC1 nor PC2 can communicate with Switch1.
|
||||
|
||||
- **PC2 → Switch1**
|
||||
- There's no connectivity because PC2's vlan has no configured IP;
|
||||
- **PC2 → PC3**
|
||||
- There's no connectivity because they are in different vlans;
|
||||
- **PC2 → 192.168.1.34**
|
||||
- There's no connectivity because the IP doesn't exist;
|
||||
- **PC3 → Switch1**
|
||||
- There's connectivity because they are in the same vlan;
|
||||
- **PC3 → PC2**
|
||||
- There's no connectivity because they are in different vlans;
|
||||
- **PC3 → 192.168.1.34**
|
||||
- There's no connectivity because the IP doesn't exist;
|
||||
- **Switch1 → PC3**
|
||||
- There's connectivity because they are in the same vlan;
|
||||
- **Switch1 → 192.168.1.34**
|
||||
- There's no connectivity because the IP doesn't exist;
|
||||
|
||||
ARP packets occur in every new communication in the same link. ICMP packets only occur when there is connectivity through the link.
|
||||

|

|
||||
## Ex 2.2
|
||||
|
||||
|Ping from:|Ping to: |Connectivity|Filtered Packets|
|
||||
|:--------:|:-------:|:----------:|:--------------:|
|
||||
| PC1 | Switch1 | Yes | N/A |
|
||||
| PC1 | Switch2 | Yes | ARP, ICMP |
|
||||
| PC1 | PC2 | No | ARP |
|
||||
| PC1 | PC3 | No | ARP |
|
||||
| PC2 | Switch1 | No | ARP |
|
||||
| PC2 | Switch2 | No | ARP |
|
||||
| PC2 | PC2 | Yes | N/A |
|
||||
| PC2 | PC3 | Yes | ARP, ICMP |
|
||||
|
||||
- PC1 → Switch1
|
||||
- There's connectivity because they are in the same vlan;
|
||||
- PC1 → Switch2
|
||||
- There's connectivity because they are in the same vlan;
|
||||
- PC1 → PC2
|
||||
- There's no connectivity because they are in different vlans;
|
||||
- PC1 → PC3
|
||||
- There's no connectivity because they are in different vlans;
|
||||
- PC2 → Switch1
|
||||
- There's no connectivity because they are in different vlans;
|
||||
- PC2 → Switch2
|
||||
- There's no connectivity because they are in different vlans;
|
||||
- PC2 → PC2
|
||||
- There's connectivity because it's connecting with itself;
|
||||
- PC2 → PC3
|
||||
- There's connectivity because they are in the same vlan;
|
||||
|
||||
The appearances of packets in this case is similar to the ones in Ex 1.5.

## Ex 3.5

|
||||
|Ping from:|Ping to: |Connectivity|Filtered Packets|
|
||||
|:--------:|:-----------:|:----------:|:---------:|
|

||||
| PC5 | PC4 | Yes | ICMP |
|
||||
| PC5 | 192.1.1.100 | No | ICMP |
|
||||
|
||||
- PC4 → Switch4
|
||||
- There's no connectivity because they are in different vlans and there are no valid routes between them;
|
||||
- PC4 → Router
|
||||
- There's connectivity because there's a valid route between them;
|
||||
- PC4 → PC5
|
||||
- There's connectivity because, even though they are in different vlans, there's a valid route through the router
|
||||
- PC4 → 192.1.1.100
|
||||
- There's no connectivity because the destination doesn't exist;
|

- PC5 → Switch4
|

- There's no connectivity because they are in different vlans and there are no valid paths between them;

***************************************************************
|
||||
This is a normal Router with a SW module inside (NM-16ESW)
|
||||
It has been preconfigured with hard coded speed and duplex
|
||||
|
||||
To create vlans use the command "vlan database" from exec mode
|
||||
After creating all desired vlans use "exit" to apply the config
|
||||
|
||||
To view existing vlans use the command "show vlan-switch brief"
|
||||
|
||||
Warning: You are using an old IOS image for this router.
|
||||
Please update the IOS to enable the "macro" command!
