HSRP & VRRP Questions 2

January 29th, 2021 Go to comments

Question 1

Explanation

The “virtual MAC address” is 0000.0c07.acXX (XX is the hexadecimal group number) so it is using HSRPv1.

Note: HSRP Version 2 uses a new MAC address which ranges from 0000.0C9F.F000 to 0000.0C9F.FFFF.

Question 2

Question 3

Explanation

From the output exhibit, we notice that the key-string of R1 is “Cisco123!” (letter “C” is in capital) while that of R2 is “cisco123!”. This causes a mismatch in the authentication so we have to fix their key-strings.

Note:

key-string [encryption-type] text-string: Configures the text string for the key. The text-string argument is alphanumeric, case-sensitive, and supports special characters.

Question 4

Explanation

In HSRP version 1, group numbers are restricted to the range from 0 to 255. HSRP version 2 expands the group number range from 0 to 4095 -> We must configure HSRP group 300 so we must change to HSRP version 2.

    RE Q3:
    The key chain config on the upper left of the sample output shows “Cisco123!”

    The key chain value shown on the lower left of the sample output shows “cisco123!”

    Unless something is missing, that is impossible and the data shown in the lower left is incorrect for this question.

    @zaphod are you possibly mixing chain and key-string? The key-string is the issue.
