R3303-HP HSR6800 Routers MPLS Command Reference

152
Examples
# Enable FRR for tunnel interface Tunnel0, so the tunnel can use an available bypass tunnel in case the
protected link or node that it traverses fails.
<Sysname> system-view
[Sysname] interface tunnel 0
[Sysname-Tunnel0] mpls te fast-reroute
mpls te fast-reroute bypass-tunnel
Use mpls te fast-reroute bypass-tunnel to specify a bypass tunnel for the protected interface.
Use undo mpls te fast-reroute bypass-tunnel to remove the specified bypass tunnel.
Syntax
mpls te fast-reroute bypass-tunnel tunnel tunnel-number
undo mpls te fast-reroute bypass-tunnel tunnel tunnel-number
Views

Default command level
2: System level
Parameters
tunnel tunnel-number: Specifies a bypass tunnel by its tunnel number.
Usage guidelines
This command is not supported when the signaling protocol is CR-LDP.
You can specify multiple bypass tunnels for the protected interface. A maximum of three bypass tunnels
can be specified for a protected interface.
A bypass tunnel cannot be used for services like VPN at the same time.
When you specify a bypass tunnel, make sure that:
• The state of the tunnel is up.
• The protected interface is not the outgoing interface in the route entries for the LSP of the bypass
tunnel.
Examples
# Use tunnel 0 as the bypass tunnel to protect the link connected to interface GigabitEthernet 2/1/1.
<Sysname> system-view
[Sysname] interface giabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] mpls te fast-reroute bypass-tunnel tunnel 0
mpls te igp advertise
Use mpls te igp advertise to enable IGP to advertise the MPLS TE tunnel as a link to IGP neighbors.
Use undo mpls te igp advertise to remove the configuration.
