R1 and R2 are using VRRP for high availability.
Referring to the exhibit, which two statements are correct about the configuration? (Choose two.)
Click on the arrows to vote for the correct answer
A. B. C. D.BC
The given configuration shows that both routers R1 and R2 are using VRRP (Virtual Router Redundancy Protocol) for high availability. VRRP allows multiple routers to participate in a virtual router group that shares a virtual IP address. One router in the group is elected as the master router, which is responsible for forwarding traffic sent to the virtual IP address. The other routers in the group act as backup routers, ready to take over if the master router fails.
From the given configuration, we can see that R1 and R2 are using VRRP group 1, with a virtual IP address of 10.200.12.254. The priority value is also configured for each router, with R1 having a higher priority of 150 and R2 having the default priority of 100. This means that R1 will become the master router for VRRP group 1 by default, but R2 can become the master if certain conditions are met.
Now let's look at the given answer choices:
A. R2 is the backup router and will become the master router if ge-1/0/0 on R1 goes down. This statement is incorrect because ge-1/0/0 is not part of the VRRP configuration, so it cannot affect the election of the master router.
B. R2 is the backup router and will remain the backup router if ge-1/0/0 on R1 goes down. This statement is correct because ge-1/0/0 is not part of the VRRP configuration, so it cannot affect the election of the master router. R2 will remain the backup router unless the VRRP priority values are changed or R2's interface goes down.
C. If R1 goes down, R2 will become the master and will relinquish mastership once R1 comes back online. This statement is correct because R2 has a lower priority than R1, so it will become the master router if R1 goes down. Once R1 comes back online, it will resume its role as the master router and R2 will revert to being a backup router.
D. If R1 goes down, R2 will become the master and will remain the master once R1 comes back online. This statement is incorrect because R1 has a higher priority than R2, so it will become the master router once it comes back online. R2 will revert to being a backup router.
In summary, the correct statements about the configuration are:
