Connectivity between three routers

[Ian Dewar]

Can you help with the following lab. config?

Connectivity between three routers has been established, and IP services must be configured in the order presented to complete the implementation. 

1. All traffic sent from R3 to the R1 Loopback address must be configured for NAT on R2.

2. All source addresses must be translated from R3 to the IP address of Ethernet0/0 on R2, while using only a standard access list named PUBNET.

3. To verify, a ping must be successful to the R1 Loopback address sourced from R3. Do not use NVI NAT configuration.

this solution for your case

[Ian Dewar]

1. And to name the access list?:

conf t

access- list PUBNET

Question - Why is the IP 192.168.3.0 when the task says NAT to be configured on R2. which is 192.168. 2 .0?

And this is task 2? 

3. And ping 192.168.1.1

conf t

access- list PUBNET
ANSWER:- I am not so sure that the standard ACL support NAMED, as I know only extended ACL, try use NAMED, and I also will try 

Question - Why is the IP 192.168.3.0 when the task says NAT to be configured on R2. which is 192.168. 2 .0?

And this is task 2?
ANSWER:-NO read the the task, it mention you need to NATing the R3 not R2 LO

3. And ping 192.168.1.1
ANSWER:- in R3 
ping 192.168.1.1 source 192.168.3.1

Remember first thing is force traffic of R3 to go via R2 not direct to R1'

I Mention the cost need to change of ospf for each link

[Ian Dewar]

So ip access- list extended PUBNET

Configure SSH connectivity from R1 to R3, while excluding access via other remote connection protocols.

Access for user netadmin and password N3t4ccess must be set on router R3 using RSA and 1024 bits.

Verify connectivity using an SSH session from router R1 using a destination address of 10.1.3.11. Do NOT modify console.

you need VMware in GNS3 to run SSH, this lab can be done in basic packert tracer and GNS3

[Ian Dewar]

I have this:

SSH:

R3(config)# username netadmin password N3t4ccess

R3(config)# line vty 0 4

R3(config-line)# login local

R3(config-line)# exit

R3(config)# ip domain-name cisco.com

R3(config)# crypto key generate rsa

1. Can you verify if this correct?

2. Can you help with: Verify connectivity using an SSH session from router R1 using a destination address of 10.1.3.11. Do NOT modify console.

[MHM Cisco World]

For destination of ssh I am not clear get what İp you use. 

For ssh config 

Two points 

1- you must add enable password

2-you must add transport input in ssh under vty line

Other config is correct 

Thanks

SSH:

R3(config)# username netadmin password N3t4ccess

R3(config)# line vty 0 4

R3(config)# transport input ssh

R3(config-line)# login local

R3(config-line)# exit

R3(config)# ip domain-name cisco.com

R3(config)# crypto key generate rsa
