Configuring Manual Bypass Tunnels
Consider the following network setup.
The user first configures the option to disable the dynamic bypass tunnels.
Listed below are the steps to configure the manual bypass tunnels:
1. Configure the option to disable the dynamic bypass tunnels on the 7210 SAS node B
(if required). The CLI for this configuration is:
config>router>mpls>dynamic-bypass [disable | enable]
The dynamic bypass tunnels are enabled by default.
2. Configure an LSP on node B, such as B-E-F-C which is used only as bypass. The user
specifies each hop in the path, for example, the bypass LSP has a strict path.
Note that including the bypass-only keyword disables the following options under the LSP
configuration:
•bandwidth
• fast-reroute
• secondary
The following LSP configuration options are allowed:
• adaptive
• adspec
• cspf
•exclude
• hop-limit
• include
•metric
The following example displays a bypass tunnel configuration:
A----B----C----D

E----F
