Step 3 Run:
mpls
MPLS is enabled globally and the MPLS view is displayed.
By default, no node is enabled with MPLS globally.
Step 4 Run:
quit
The system view is displayed.
Step 5 Run:
mpls ldp
LDP is enabled globally and the MPLS-LDP view is displayed.
By default, no node is enabled with LDP globally.
Step 6 (Optional) Run:
lsr-id lsr-id
An LSR ID is set for an LDP instance.
The default LSR ID of an LDP instance is the LSR ID of the LSR where the LDP instance is
configured. Using the default value is recommended.

2.4.3 (Optional) Configuring the Dynamic LDP Advertisement
Capability
On LSRs enabled with global LDP, the dynamic LDP advertisement capability allows extended
LDP functions to be dynamically enabled or disabled when the LDP session is working properly,
ensuring stable LSP operation.
Context
On an LSR disabled from the dynamic LDP negotiation capability, if an extended LDP function
is enabled after an LDP session has been created, the LDP session will be interrupted and the
extended LDP function will be negotiated, affecting LSP stability. The dynamic LDP
advertisement capability allows an extended LDP function to be enabled or disabled dynamically
during proper operation of an LDP session, ensuring LSP stability.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
Issue 01 (2011-12-30)
NOTE
Enabling this function immediately after LDP is enabled globally is recommended. The dynamic LDP
advertisement capability does not affect existing LDP functions.
Before the dynamic LDP advertisement capability is enabled, MPLS and LDP must be enabled globally.
