In certain versions of IOS, a number of configuration commands have both MPLS and tag-switching forms and will be supported during the transition from a tag-switching environment to a standards-based MPLS environment. We have used predominantly the tag-switching commands within this publication, but the following table provides a reference which documents some of the more common tag-switching commands and their MPLS equivalent form.
LDP Command |
TDP Command |
Description |
---|---|---|
mpls ldp advertise-labels |
tag-switching advertise-labels |
Controls the distribution of locally assigned (incoming) labels by LDP/TDP |
mpls ldp atm control-mode |
tag-switching atm allocation-mode |
Controls the mode used for handling label-binding requests on LC-ATM interfaces |
mpls ldp atm vc-merge |
tag-switching atm vc-merge |
Controls whether the vc-merge capability is supported for unicast label VCs |
mpls ldp maxhops |
tag-switching atm maxhops |
Limits the number of hops permitted in an LSP established by the downstream on demand method of label distribution |
mpls ip (global) |
tag-switching ip (global) |
Enables MPLS forwarding of IPv4 packets along normally routed paths for the platform |
mpls ip (interface) |
tag-switching (interface) |
Enables MPLS forwarding of IPv4 packets along normally routed paths for a particular interface |
mpls ldp discovery |
tag-switching tdp discovery |
Configures the interval between transmission of consecutive LDP/TDP discovery hello messages, the hold time for a discovered LDP/TDP neighbor, or the neighbors from which requests for targeted hellos may be honored |
mpls ldp holdtime |
tag-switching tdp holdtime |
Changes the time for which an LDP/TDP session is maintained in the absence of LDP/TDP messages from the session peer |
show mpls atm-ldp bindings |
show tag-switching atm-tdp bindings |

show mpls atm-ldp capability |
show tag-switching atm-tdp capability |
Displays the ATM MPLS capabilities negotiated with LDP/TDP neighbors for LC-ATM interfaces |
show mpls interfaces |
show tag-switching interfaces |
Displays information about one or more interfaces that have been configured for label switching |
show mpls ldp bindings |
show tag-switching tdp bindings |
Displays the contents of the label information base (LIB) |
show mpls ldp discovery |
show tag-switching tdp discovery |
Displays the status of the LDP/TDP discovery process |
show mpls ldp neighbor |
show tag-switching tdp neighbor |
Displays the status of LDP/TDP sessions |
show mpls ldp parameters |
show tag-switching tdp parameters |
