• Password requirement for the neighbor (required or not required).
• Password source in the current configuration. The source is described by one of the following:
– neighbor—The password for the neighbor is retrieved from the mpls ldp neighbor [vrf
vrf-name] ip-address password [0 | 7] password command. The ip-address argument is the
router ID of the neighbor.
– num—The password for the neighbor is retrieved from mpls ldp [vrf vrf-name]
password option nu
mber for acl [0 | 7] password command. The number argument is a number
from 1 to 32767. The acl argument is the name or number of an IP standard access list that
