MPLS Interface tab fields


Field Description
Index
Displays either the slot/port number of the interface or the CLIP ID.
Lay3Addr
Configures the IP address for this interface.
Lay3Mask
Configures the mask for this interface.
AdminStatus
Enables or disables the specified interface. You can use this field to temporarily disable an interface while you change a parameter setting or perform some network maintenance.
LabelDistMode
Specifies how an LSR binds a label to a FEC. The default is independent.
  • independent --In this mode, each LSR makes an independent decision about binding a label to a FEC and distributes that binding to its peers.
  • ordered -- In this mode, only the egress LER can bind a label to a FEC and distribute that binding to its peers.
LabelUseMode
Specifies when the interface should use the label for the next hop. The default is immediate.
  • immediate --The interface uses the label immediately. Use when the global LDP loop detection flag is disabled.
  • notImmediate --The interface defers using the label until the end of loop detection operations. Use when the global LDP loop detection flag is enabled.
PenultimatePopRequest
Setting this flag to true sets "implicit" mode to true. This causes the upstream LSR to pop the label stack if it is the penultimate (next-to-last) hop in the MPLS network. The default value is true.
LabelRequestMode
Specifies when an upstream LSR requests a label from a downstream LSR. The default is requestNever.
  • requestNever --The interface never requests a label. Use only in combination with the downstream unsolicited advertise mode and liberal label retention mode.
  • requestWhenNeeded -- The interface requests a label only when it needs one.
  • requestOnRequest --The interface requests a label only when it receives a request from another LSR.
LabelProtocol
Configures the label distribution protocol for the specified interface.
  • LDP--Nortel Networks recommends using this protocol so CLIP interfaces can establish LDP targets.
    This is the default protocol.
  • RSVP --Trunk ports should always be set to RSVP.
    Nortel Networks only supports RSVP on trunk ports.
  • Both--Configures LDP and RSVP to be the label distribution protocols on the specified interface.
