Hi Folks,
LSPs must be tagged for node-link protection to make use of the bypass LSPs, and you can provide an ERO list to influence the CSPF-based routing of the bypass LSP.

Syntax
bypass bypass-name {
bandwidth bps;
description text;
hop-limit number;
no-cspf;
path address <strict | loose>;
priority setup-priority reservation-priority;
to address;
}
Description
Enables you to configure specific bandwidth and path constraints for a bypass LSP. It is possible to individually configure multiple bypass LSPs. If you do not configure the bypass LSPs individually, they all share the same path and bandwidth constraints.
If you specify the bandwidth, hop-limit, and path statements for the bypass LSP, these values take precedence over the values configured at the [edit protocols rsvp interface interface-name link-protection] hierarchy level. The other attributes (subscription, no-node-protection, and optimize-timer) are inherited from the general constraints.
Options
bypass-name—(Required) Specify a name for the bypass LSP. The name can be up to 64 characters.
description—Provides a textual description of the bypass LSP. Enclose any descriptive text that includes spaces in quotation marks (" "). Any descriptive text you include is displayed in the output of the show mpls lsp bypass detail command and has no effect on the operation of the bypass LSP. The description text can be no more than 80 characters in length.
to address—(Required) Specify the address for the interface of the immediate next-hop node (for link protection) or the next-next-hop node (for node-link protection). The address specified determines whether this is a link protection bypass or a node-link protection bypass. On multiaccess networks (for example, a LAN), this address is also used to specify which next-hop node is being protected.
The remaining statements are explained separately.
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
