Macro names must start with a letter, digit, or underscore, and may contain any of those characters. Macro names may not be reserved words (for example, .Ic cost ) . Macros are not expanded inside quotes. .Pp For example: .Bd -literal -offset indent hi="2" interface em0 { cost $hi } .Ed .Sh GLOBAL CONFIGURATION All interface related settings can be configured globally and per interface. The only settings that can be set globally and not overruled are listed below. .Pp .Bl -tag -width Ds -compact .It Xo .Ic fib-update .Pq Ic yes Ns | Ns Ic no .Xc If set to .Ic no , do not update the Label Forwarding Information Base, a.k.a. the kernel routing table. The default is .Ic yes . .Pp .It Ic router-id Ar address Set the router ID; in combination with labelspace it forms the LSR-ID. .Pp .It Ic keepalive Ar seconds Set the keepalive timeout in seconds. The default value is 180; valid range is 1\-65535. .Pp .It Xo .Ic targeted-hello-accept .Pq Ic yes Ns | Ns Ic no .Xc If set to .Ic yes , allow LDP sessions to be established with remote neighbors that have not been specifically configured. The default is .Ic no . .El .Sh INTERFACES Each interface can have several parameters configured individually, otherwise they are inherited. .Bd -literal -offset indent interface em0 { } .Ed .Pp Interface-specific parameters are listed below. .Bl -tag -width Ds .It Ic link-hello-holdtime Ar seconds Set the hello holdtime in seconds. The maximum time .Xr ldpd 8 will wait between two consecutive hello messages from a peer before it is marked as being down. The default value is 15. .It Ic link-hello-interval Ar seconds Set the hello interval in seconds. The default value is 5; valid range is 1\-65535. .El .Sh TARGETED NEIGHBORS Each targeted neighbor can have several parameters configured individually, otherwise they are inherited. .Bd -literal -offset indent targeted-neighbor A.B.C.D { } .Ed .Pp Targeted-neighbor specific parameters are listed below. .Bl -tag -width Ds .It Ic targeted-hello-holdtime Ar seconds Set the hello holdtime in seconds. The maximum time .Xr ldpd 8 will wait between two consecutive hello messages from a peer before it is marked as being down. The default value is 45. .It Ic targeted-hello-interval Ar seconds Set the hello interval in seconds. The default value is 5; valid range is 1\-65535. .El .Sh NEIGHBORS The .Ic neighbor section allows for the configuration of neighbor-specific parameters. Note, however, that .Xr ldpd 8 uses the hello discovery mechanism to discover its neighbors. Without an underlying adjacency these commands have no effect. .Bd -literal -offset indent neighbor A.B.C.D { } .Ed .Pp Neighbor-specific parameters are listed below. .Bl -tag -width Ds .It Ic password Ar secret Enable TCP MD5 signatures per RFC 5036. .El .Sh LAYER 2 VPNS .Xr ldpd 8 implements the signaling of pseudowires which can be used to implement either the VPWS solution (also known as PWE3) or the VPLS solution. Currently only the VPLS solution is supported. .Bd -literal -offset indent l2vpn name type vpls { bridge bridge0 interface em1 pseudowire mpw1 { pw-id 100 neighbor 192.168.1.10 } pseudowire mpw2 { pw-id 200 neighbor 10.0.1.5 } } .Ed .Pp Layer 2 VPN specific parameters are listed below. .Bl -tag -width Ds .It Xo .Ic type .Pq Ic ethernet Ns | Ns Ic ethernet-tagged .Xc Specify the type of the configured pseudowires. The type must be the same at both endpoints. The default is .Ic ethernet . .Pp .It Ic mtu Ar number Set the MTU advertised in the pseudowires. Local and remote MTUs must match for a pseudowire to be set up. The default value is 1500. .Pp .It Ic bridge Ar interface Set the bridge interface the VPLS is associated with. This parameter is optional and is only used to remove MAC addresses received from MAC address withdrawal messages. Only one bridge interface can be set. .Pp .It Ic interface Ar interface Configure a non pseudowire interface pertaining to the VPLS. This parameter is optional and is only used to send MAC address withdrawal messages when the specified interface is shutdown. Multiple interfaces can be configured. .Sh PSEUDOWIRES Each .Xr mpw 4 pseudowire interface can have several parameters configured individually, otherwise they are inherited. A pseudowire interface is specified by its name. .Bd -literal -offset indent pseudowire mpw5 { pw-id 5000 neighbor 172.16.1.50 } .Ed .Pp Pseudowire-specific parameters are listed below. .Bl -tag -width Ds .Pp .It Ic neighbor Ar address Specify the endpoint of the pseudowire on the remote PE router. A targeted neighbor will automatically be created for this address. .Pp .It Ic pw-id Ar number Set the PW ID used to identify the pseudowire. The PW ID must be the same at both endpoints. Valid range is 1\-4294967295. .It Xo .Ic status-tlv .Pq Ic yes Ns | Ns Ic no .Xc Specify whether the use of the Status TLV is preferred or not preferred. The default is .Ic yes . .It Xo .Ic control-word .Pq Ic yes Ns | Ns Ic no .Xc Specify whether the use of the control word is preferred or not preferred. The default is .Ic yes . .Sh FILES .Bl -tag -width "/etc/ldpd.conf" -compact .It Pa /etc/ldpd.conf .Xr ldpd 8 configuration file .El .Sh SEE ALSO .Xr ldpctl 8 , .Xr ldpd 8 , .Xr rc.conf.local 8 .Sh HISTORY The .Nm file format first appeared in .Ox 4.6 .
