3.20.6.1 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
3.20.7 Configuring Manual Bypass Tunnels
Consider the following network setup in Figure 15. Assume that a manual bypass
tunnel must be configured on Node B.
