Follow these steps to configure a bypass tunnel on its PLR:
To do...
Enter system view
Enter interface view of the
bypass tunnel
Specify the destination address
of the bypass tunnel
Configure the bandwidth and
type of LSP that the bypass
tunnel can protect
Submit current tunnel
configuration
Exit to system view
Enter interface view of the
outgoing interface of the
protected LSP
Bind the bypass tunnel with the
protected interface
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.
Configuring node protection
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:
To do...
Enter system view
Enter MPLS view
Enable RSVP hello extension
on current node
Exit to system view
Use the command...
system-view
interface tunnel
tunnel-number
destination ip-address
mpls te backup bandwidth
{ bandwidth | { bc0 | bc1 }
{ bandwidth | un-limited } }
mpls te commit
quit
interface interface-type
interface-number
mpls te fast-reroute
bypass-tunnel tunnel
tunnel-number
Use the command...
system-view
mpls
mpls rsvp-te hello
quit
