Task 1
Configure timers in RIP domain as follows:

• Advertisements: 15 seconds
• Invalid: 90 seconds
• Holddown: 90 seconds
• Flush: 120 seconds

Ensure that RIP convergence between R1 and R3 uses default timers.

Task 1
Configure RIP authentication between R1 and R3 using clear text method. Use key 1, and the password CISCO13.

Task 2
Configure RIP authentication between R2 and R3 using MD5 method. Use key 1, and the password CISCO23.

Task 1
Change encapsulation on Serial0/1 interfaces between R1 and R3 to PPP. Configure R1, so that it receives the IP address: 10.1.13.1 from R3 using IPCP.


Task 2
Configure R1 so it installs RIP updates sent by R3.

Lab Solution

Task 1
Change encapsulation on Serial0/1 interfaces between R1 and R3 to PPP. Configure R1, so that it receives the IP address 10.1.13.1 from R3 using IPCP.


R1 Configuration:

!

interface Serial0/1
 ip address negotiated
 encapsulation ppp
 serial restart-delay 0

!

R3 Configuration:

!

interface Serial0/1
 ip address 10.1.13.3 255.255.255.0
 encapsulation ppp
 peer default ip address 10.1.13.1
 serial restart-delay 0

!

Note!
For this IP address to be assigned, the LCP negotiation must take place (shut, no shut on s0/1 interface).

Verification:

Pic. 2 - R1's Address Assigned via IPCP.

Pic. 3 - R3's Connected Networks.

Pic. 4 - R1's Connected Networks.

Notice!

R1 installs two host routes (/32) in its routing table. R3 installs a host route but has the /24 subnet entry as well. The result is that R1 and R3 are not on the common subnet.

Task 2
Configure R1 so it installs RIP updates sent by R3.
R1 Configuration:
