Questions 66

If an Alcatel-Lucent 7750 LSR receives a labeled packet with a outer label TTL of 250 and an inner label TTL of 251, which of the following statements is true?

Options:

The packet will be label switched; the outer label TTL will be 249 and the inner label TTL will be 250.

The packet will be label switched; the outer label TTL will be 249 and the inner label TTL will be 251.

The packet will be label switched; both the outer label TTL and the inner label TTL will be 250.

The packet will be label switched; both the outer label TTL and the inner label TTL will be 249, because they must be the same.
