You can specify the maximum number of dynamic bypass LSPs permitted for protecting an interface using the max-bypasses statement at the [edit protocols rsvp interface interface-name link-protection] hierarchy level. When this statement is configured, multiple bypasses for link protection are enabled. Call admission control (CAC) is also enabled.
By default, this option is disabled and only one bypass is enabled for each interface. You can configure a value of between 0 through 99 for the max-bypasses statement. Configuring a value of 0 prevents the creation of any dynamic bypass LSPs for the interface. If you configure a value of 0 for the max-bypasses statement, you need to configure one or more static bypass LSPs to enable link protection on the interface.
If you configure the max-bypasses statement, you must also configure the bandwidth statement (discussed in Configuring the Bandwidth for Bypass LSPs).
To configure the maximum number of bypass LSPs for a protected interface, include the max-bypasses statement:
-
max-bypasses number;
You can include this statement at the following hierarchy levels:
