A network engineer must configure the router R1 GigabitEthernet1/1 (CCNA 200-301)
A network engineer must configure the router R1 GigabitEthernet1/1 interface to connect to the router R2 GigabitEthernet1/1 interface. For the configuration to be applied, the engineer must compress the address 2001:0db8:0000:0000:0500:000a:400F:583B.
Which command must be issued on the interface?
A. ipv6 address 2001::db8:0000::500:a:400F:583B
B. ipv6 address 2001:db8:0::500:a:4F:583B
C. ipv6 address 2001:db8::500:a:400F:583B
D. ipv6 address 2001:0db8::5:a:4F:583B
Solution
Correct answer: C. ipv6 address 2001:db8::500:a:400F:583B.
Explanation:
The given IPv6 address is 2001:0db8:0000:0000:0500:000a:400F:583B. To compress this address, we can use the following rules:
Remove the leading zeros in each group of hexadecimal digits.
Replace any consecutive groups of zeros with a double colon (::).
Applying these rules, the compressed version of the address becomes:
2001:db8::500:a:400F:583B
Therefore, the command that must be issued on the interface is:
ipv6 address 2001:db8::500:a:400F:583B
The other options are incorrect:
A. ipv6 address 2001::db8:0000::500:a:400F:583B
This is not a valid compressed IPv6 address, as it still contains unnecessary zeros.
B. ipv6 address 2001:db8:0::500:a:4F:583B
This is not a valid compressed IPv6 address, as it does not correctly represent the original address.
D. ipv6 address 2001:0db8::5:a:4F:583B
This is not a valid compressed IPv6 address, as it does not correctly represent the original address.
