ip-address — specifies the IP address of the next hop towards the LSP egress router. If
an ARP entry for the next hop exists, then the static LSP is marked operational. If an
ARP entry does not exist, the software sets the operational status of the static LSP
to down and continues to send an ARP request for the configured next hop at fixed
intervals.
to
Syntax to ip-address
Context config>router>mpls>static-lsp
Description This command specifies the system IP address of the egress router for the static LSP. For
LSPs that are used as transport tunnels for services, the to ip-address must be the system
IP address. If the to ip-address does not match the SDP address, the LSP is not included in
the SDP definition.
This command is required when creating an LSP.
Default n/a
Parameters ip-address — identifies the egress router system address
Values a.b.c.d
static-lsp-fast-retry
Syntax static-lsp-fast-retry seconds
no static-lsp-fast-retry
Context config>router>mpls
Description This command specifies the fast-retry timer that can be configured for static LSPs. When a
static LSP is trying to come up, MPLS tries to resolve the ARP entry for the next hop of the
LSP. If the next hop is still down or unavailable, the request may fail. In that case, MPLS starts
a non-configurable timer of 30 seconds before making the next request. The fast-retry timer
allows the user to configure a shorter retry timer so that the LSP comes up shortly after the
next hop is available.
Default 30
Parameters seconds — fast-retry timer value, in seconds
Values 1 to 30
