The document describes configuring VRRP (Virtual Router Redundancy Protocol) on routers R1 and R2. It involves: 1. Configuring R1 as the master for VRRP group 1 using virtual IP 10.0.0.254 and authentication. 2. Configuring R2 as the master for load-balanced VRRP group 2 using virtual IP 10.0.0.193 and a different authentication string. 3. Enabling tracking on both routers so that the priority of the backup router decreases if the route to the opposite network fails, allowing it to take over as master.

1. Lab 19: VRRP (Virtual Router Redundancy Protocol)
Task
1. Configure IP Address as per given in toplogy.
2. Configure DNS Server on Server as per given in topology and Make sure ISP ping all the DNS.
3. Configure Routing Protocol in between HQ, R1 and R2.
4. Configure VRRP between R1 and R2. Use Virtual IP 10.0.0.254 for VRRP.
5. Make sure R1 is Master for VRRP. Do possible configuration.
6. Make sure VRRP use MD5 authentication with password "netwaxlab@109".
7. Configure VRRP Load Balancing using group number. Use Virtual IP 10.0.0.193. Make sure R2 is
master.
8. Make sure Authentication is enable for VRRP Load Balancing use key-string as
"Blog.Eincop.com@109".
9. Make sure Tracking is enable in VRRP.
10. Configure PC1 and PC4 send traffic via 10.0.0.254 and rest of all PC's send traffic via 10.0.0.193.

Solution
 Task 2: Configure DNS Server on Server as per given in topology and Make sure ISP ping all the
DNS.

ip route 100.100.100.101 255.255.255.255 88.25.34.199
 Task 3: Configure Routing Protocol in between HQ, R1 and R2.

exit
 Task 4: Configure VRRP between R1 and R2. Use Virtual IP 10.0.0.254 for VRRP.
R1
interface FastEthernet0/1
vrrp 1 ip 10.0.0.254
exit
R2
interface FastEthernet0/1
vrrp 1 ip 10.0.0.254
exit
 Task 5: Make sure R1 is Master for VRRP. Do possible configuration.
R1
interface FastEthernet0/1
vrrp 1 priority 110
exit
 Task 6: Make sure VRRP use MD5 authentication with password "netwaxlab@109".
R1
interface FastEthernet0/1
vrrp 1 authentication md5 key-string netwaxlab@109
exit
R2
interface FastEthernet0/1
vrrp 1 authentication md5 key-string netwaxlab@109
exit

 Task 7: Configure VRRP Load Balancing using group number. Use Virtual IP 10.0.0.193. Make
sure R2 is master.
R1
interface FastEthernet0/1
vrrp 2 ip 10.0.0.193
exit
R2
interface FastEthernet0/1
vrrp 2 ip 10.0.0.193
vrrp 2 priority 110
exit
 Task 8: Make sure Authentication is enable for VRRP Load Balancing use key-string as
"Blog.Eincop.com@109".
R1
interface FastEthernet0/1
vrrp 2 authentication md5 key-string Blog.Eincop.com@109
exit
R2
interface FastEthernet0/1
vrrp 2 authentication md5 key-string Blog.Eincop.com@109
exit
 Task 9: Make sure Tracking is enable in VRRP.
R1

interface FastEthernet0/1
vrrp 1 track 1 decrement 20

vrrp 2 track 1 decrement 20
exit
 Task 10: Configure PC1 and PC4 send traffic via 10.0.0.254 and rest of all PC's send traffic via
10.0.0.193.
(Note: Use your PC interface and configure default gateway as per given in task.)
