swap
Syntax swap {out-label | implicit-null-label} nexthop ip-address
no swap {out-label | implicit-null-label}
Context config>router>mpls>interface>label-map
Description This command swaps the incoming label and specifies the outgoing label and next hop IP address on
an LSR for a static LSP.
The no form of this command removes the swap action associated with the in-label.
Default none
Parameters implicit-null-label — Specifies the use of the implicit label value for the outgoing label of the swap
operation.
out-label — Specifies the label value to be swapped with the in-label. Label values 16 through
1,048,575 are defined as follows:
Label values 16 through 31 are reserved.
Label values 32 through 1,023 are available for static assignment.
Label values 1,024 through 2,047 are reserved for future use.
Label values 2,048 through 18,431 are statically assigned for services.
Label values 28,672 through 131,071 are dynamically assigned for both MPLS and services.
Label values 131,072 through 1,048,575 are reserved for future use.
Values 16 — 1048575
nexthop ip-address — The IP address to forward to. If an ARP entry for the next hop exists, then the
static LSP will be marked operational. If ARP entry does not exist, software will set the
operational status of the static LSP to down and continue to ARP for the configured nexthop.
Software will continuously try to ARP for the configured nexthop at a fixed interval.
static-lsp
Syntax [no] static-lsp lsp-name
Context config>router>mpls
Description This command is used to configure a static LSP on the ingress router. The static LSP is a manually
setup LSP where the nexthop IP address and the outgoing label (push) must be specified.
The no form of this command deletes this static LSP and associated information.
The LSP must be shutdown first in order to delete it. If the LSP is not shut down, the no static-lsp lsp-
name command generates a warning message on the console indicating that the LSP is
administratively up.
Parameters lsp-name — Name that identifies the LSP.
Values Up to 32 alphanumeric characters.
