Enabling the TE FRR and Configuring the Auto Bypass Tunnel Attributes
Context
After TE Auto FRR is enabled, the system automatically sets up a bypass tunnel.
Perform the following configurations on the ingress node of the primary MPLS TE tunnel.
Procedure
- Run system-view
The system view is displayed.
- Run interface tunnel interface-number
The tunnel interface view of the primary tunnel is displayed.
- Run mpls te fast-reroute [ bandwidth ]
The TE FRR is enabled.
To guarantee the tunnel bandwidth, you must specify the parameter bandwidth.
- (Optional) Run mpls te bypass-attributes [ bandwidth bandwidth ] [ priority setup-priority [ hold-priority ] ]
The attributes of the bypass tunnel are configured.
The bypass tunnel attributes can be configured only after the mpls te fast-reroute bandwidth command is run on the primary tunnel.
- The bandwidth of the bypass tunnel cannot be greater than the bandwidth of the primary tunnel.
- When the attributes of the automatic bypass tunnel are not configured, by default, the bandwidth of the automatic bypass tunnel is the same as the bandwidth of the primary tunnel.
- The setup priority of the bypass tunnel cannot be higher than the holding priority. Both priorities cannot be higher than the priority of the primary tunnel.
When the bandwidth of the primary tunnel is changed or the FRR is disabled, the attributes of the bypass tunnel are cleared automatically.
- Run mpls te commit
The current configuration of the tunnel is committed.
