bypass-tunnel
Syntax
bypass-tunnel [to ip-address] [protected-lsp [lsp-name]] [dynamic | manual] [detail]
Context
show>router>mpls
Description
If fast reroute is enabled on an LSP and the facility method is selected, instead of creating a
separate LSP for every LSP that is to be backed up, a single LSP is created that serves as a
backup for a set of LSPs. This type of LSP tunnel is called a bypass tunnel.
Parameters
ip-address — specifies the IP address of the egress router
lsp-name — specifies the name of the LSP protected by the bypass tunnel
dynamic — displays dynamically assigned labels for bypass protection
manual — displays manually assigned labels for bypass protection
detail — displays detailed information
Output
The following output is an example of MPLS bypass tunnel information, and
describes the fields.
