Follow these steps to configure a bypass tunnel on its PLR: 

Enter system view 

–– 

Enter interface view of the 
bypass tunnel  

interface tunnel 
tunnel-number

 

–– 

Specify the destination address 
of the bypass tunnel 

destination ip-address 

Required 

z

 

For node protection, this is 
the LSR ID of the next hop 
router of PLR. 

z

 

For link protection, this is the 
LSR ID of the next hop 
device of PLR. 

Configure the bandwidth and 
type of LSP that the bypass 
tunnel can protect 

mpls te backup bandwidth 
{ bandwidth | { bc0 | bc1 } 
{ bandwidth | un-limited } } 

Required 
Bandwidth is not protected by 
default. 

Submit current tunnel 
configuration 

Required 

Exit to system view 

–– 

Enter interface view of the 
outgoing interface of the 
protected LSP 

 interface-type 

 

–– 

Bind the bypass tunnel with the 
protected interface 

mpls te fast-reroute 
bypass-tunnel tunnel 
tunnel-number

 

Required 

 

Bypass tunnels do not protect bandwidth by default. This can defeat your attempts to binding a primary 
LSP to a bypass tunnel. Therefore, when configuring a bypass tunnel, you must configure the 
bandwidth that it is intended to protect with the mpls te backup bandwidth command.  

 

To use FRR for node protection, you need to perform the tasks in this section on the PLR and the 
protected node. If you only need to protect links, skip this section.  

Follow these steps to configure node protection:  

Enter system view 

–– 

Enter MPLS view 

–– 

Enable RSVP hello extension 
on current node 

Required 
Disabled by default 

Exit to system view
