  1. The adjacency forms with the lower timeout value.
  2. The adjacency forms with the higher timeout value.
  3. The adjacency is in init state.
  4. The adjacency times out after 30 seconds.

Answer(s): A



An Alcatel-Lucent 7750 SR enabled with LDP has multiple equal cost paths to a given FEC. After ECMP is enabled, which of the following is FALSE?

  1. The router has new entries added for the given FEC in its LIB.
  2. The router has new entries added for the given FEC in its FI
  3. The router generates a single label for the given FEC and advertises it to all its peers,
