Configuring Basic Functions of MPLS LDP
You can build an MPLS network only after basic functions of MPLS LDP are configured.
Pre-configuration Tasks
Before configuring basic functions of MPLS LDP, configure static routes or an IGP to ensure that IP routes between LSRs are reachable.
Routing Information Protocol version 1 (RIP-1) cannot be used.
Configuration Procedure
Configure basic functions of MPLS LDP according to the following sequence.
- Configuring the LSR ID
- Enabling Global MPLS
- Enabling Global MPLS LDP
- Configuring LDP Sessions
- (Optional) Configuring LDP Session Protection
- (Optional) Configuring an LDP Transport Address
- (Optional) Configuring Timers for LDP Session
- (Optional) Configuring LDP Loop Detection
- (Optional) Configuring the LDP Label Policies
- (Optional) Disabling a Device from Distributing Labels to Remote Peers
- (Optional) Configuring a Policy for Triggering LDP LSP Establishment
- (Optional) Disabling LDP LSP Flapping Suppression
- (Optional) Disabling a Device from Forwarding Unknown TLVs
A local device can be disabled from forwarding unknown TLVs to peers. - Verifying the Configuration of Basic MPLS LDP Functions
