You Should Know:

Here are some essential commands and steps to practice networking concepts covered in CCNA:

1. Basic Network Configuration (Cisco IOS):

Enter global configuration mode:
```
enable 
configure terminal 
```
Configure a hostname for the device:
```
hostname Router1 
```

Set up an IP address on an interface:

interface GigabitEthernet0/1 
ip address 192.168.1.1 255.255.255.0 
no shutdown

2. Routing Protocols:

Configure OSPF:

router ospf 1 
network 192.168.1.0 0.0.0.255 area 0

Configure EIGRP:
```
router eigrp 100 
network 192.168.1.0 
```

3. Network Security:

Set up an access control list (ACL):

access-list 1 permit 192.168.1.0 0.0.0.255 
interface GigabitEthernet0/1 
ip access-group 1 in

Configure a basic firewall rule on ASA:

access-list OUTSIDE_IN extended permit tcp any host 192.168.1.10 eq www 
access-group OUTSIDE_IN in interface outside

4. Troubleshooting Commands:

Check the routing table:
```
show ip route 
```
Test connectivity using ping:
```
ping 192.168.1.1 
```
Verify interface status:
```
show ip interface brief 
```

5. Cloud Networking:

Use AWS CLI to create a VPC:

aws ec2 create-vpc --cidr-block 10.0.0.0/16

Configure a subnet:

aws ec2 create-subnet --vpc-id vpc-123456 --cidr-block 10.0.1.0/24
