Configuring a Fast-Retry Timer for Static LSPs

A fast-retry timer 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. This request may fail because the next hop might still be down or unavailable. In that case, MPLS starts a retry timer before making the next request. The fast-retry command allows the user to configure the retry timer so that the LSP comes up shortly after the next hop is available.

Use the following CLI syntax to configure a fast-retry timer for static LSPs:

CLI Syntax:

config>router>mpls
    static-lsp-fast-retry seconds

Example:

config>router# mpls
config>router>mpls# static-lsp-fast-retry 15
