- Keepalive interval in seconds for established peers (default: 4s)

- max-label
- Maximum number used for generated labels (default: 1048576)

Interface block supports the following parameters

- transport-address
- Transport INET4 address advertised in hellos sent on the mentioned
      interface
Neighbour block supports the following parameters
  - authenticate
- Authenticate peer using TCP MD5 signature - needs options TCP_SIGNATURE.
      Default: off
The following is an example /etc/ldpd.conf file:
# Transport address needs to be an alias for this interface
interface re0 {
	transport-address 192.168.2.2
}
# Don't send hellos on en0
interface en0 {
	passive
}
# Force a certain LDP ID
ldp-id 10.5.1.1;
# Tag also the default route
no-default-route 0;
neighbour 192.168.2.1 {
# TCP MD5 authentication - requires options TCP_SIGNATURE
	authenticate
}
 
Support for ldpd.conf first appeared in
