LDP ECMP for transit LSR

Syntax: show mpls config
MPLS OAM support for LDP ECMP
MPLS OAM support for traceroute at any transit router returns the list of labels used at that transit
router. However, traceroute is not able to exercise all ECMP paths. The forwarding plane selects one
ECMP path to forward OAM packets. All traversed labels that were returned at each transit router
are displayed at the Brocade router originating the traceroute.
Display changes to commands for LDP ECMP
The output from the show mpls forwarding command has been updated to display all ECMP paths
programmed in the forwarding plane.
NOTE
The In-lbl field does not display a value for ingress LDP LSP.

Syntax: show mpls forwarding
The output from the show mpls ldp fec prefix command has been updated to display all available
ECMP mappings on outgoing interfaces, and their corresponding next hops. When the outgoing
interface is an RSVP tunnel, the RSVP LSP name is displayed as the outgoing interface in the out_if
field. The following example displays multiple next hops created in LDP from ECMP.
