Task 2 :- configure loopback address on Router

R1 configuration 

R1(config)#
R1(config)#interface loopback 1
R1(config-if)#
R1(config-if)#*Mar  1 01:52:29.335: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback1, changed state to up

R1(config-if)#ip address 1.1.1.1 255.255.255.0
R1(config-if)#exit
R1(config)#

R2 configuration 

R2(config)#
R2(config)#interface loopback 1
R2(config-if)#
*Mar  1 01:53:55.527: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback1, changed state to up
R2(config-if)#ip address 2.2.2.2 255.255.255.0
R2(config-if)#
R2(config-if)#exit
R2(config)#

 Task 3 :- Configure Static Route on R1 and R2

 R1 configuration 

R1(config)#
R1(config)#ip route 2.2.2.0 255.255.255.0 10.1.1.2
R1(config)#ip route 2.2.2.0 255.255.255.0 20.1.1.2
R1(config)#exit
R1#show ip route static 

     2.0.0.0/24 is subnetted, 1 subnets
S       2.2.2.0 [1/0] via 20.1.1.2
                    [1/0] via 10.1.1.2
R1#

 R2 configuration 

R2(config)#
R2(config)#ip route 1.1.1.0 255.255.255.0 10.1.1.1
R2(config)#ip route 1.1.1.0 255.255.255.0 20.1.1.1
R2(config)#exit

R2#show ip route static
     1.0.0.0/24 is subnetted, 1 subnets
S       1.1.1.0 [1/0] via 20.1.1.1
                    [1/0] via 10.1.1.1 !! here we can see to reach 1.1.1.0/24 we have two path !!
 
R2#

 


-----------------------------------------------------------------------------------------------------------------


 Task 4 :- check both loopback reachability 

 ping R1 loopback to r2 loopback

 R1#ping 2.2.2.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 32/45/92 ms
R1#

   traceroute command

 R1#traceroute 2.2.2.2

Type escape sequence to abort.
Tracing the route to 2.2.2.2

 Task 5 :- configure conditional Static Route

Q :-  if we want first path best end second  patch for backup how can route modify 
 
R1 route table


R1#show ip route static
     2.0.0.0/24 is subnetted, 1 subnets
S       2.2.2.0 [1/0] via 20.1.1.2
                    [1/0] via 10.1.1.2
R1#

 if user required master path 10.1.1.2 backup path 20.1.1.2 let's modify

 R1 configuration 

R1(config)# no ip route 2.2.2.0 255.255.255.0 20.1.1.2
R1(config)#
R1(config)# ip route 2.2.2.0 255.255.255.0 20.1.1.2 100  

!! here we increase  AD Value  100 !!
R1(config)#
R1(config)#exit

R1#show ip route static
     2.0.0.0/24 is subnetted, 1 subnets
S       2.2.2.0 [1/0] via 10.1.1.2
R1#

traceroute..

R1#traceroute 2.2.2.2

Type escape sequence to abort.
