Usage guidelines
The protected interface (where the command is executed) is the outgoing interface of a primary CRLSP.
When the outgoing interface is down or a neighbor failure is detected through the BFD or hello
mechanism, the traffic of the primary CRLSP is switched to the bypass tunnel.
When you use this command, follow these restrictions and guidelines:
• You can specify up to three bypass tunnels for an interface.
• A bypass tunnel can protect up to three interfaces.
• The bypass tunnel specified by this command must be established by RSVP.
• The protected interface must not be the outgoing interface of a bypass tunnel.
Examples
# Configure tunnel interface Tunnel 0 as the bypass tunnel for GigabitEthernet 2/1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/2/1

mpls te igp advertise
Use mpls te igp advertise to enable forwarding adjacency for an MPLS TE tunnel or tunnel bundle, so IGP
advertises the MPLS TE tunnel as a link in the IGP network.
Use undo mpls te igp advertise to restore the default.
Syntax
Tunnel interface view:
mpls te igp advertise [ hold-time value ]
undo mpls te igp advertise
Tunnel bundle interface view:
mpls te igp advertise
undo mpls te igp advertise
Default
Forwarding adjacency is disabled for an MPLS TE tunnel or tunnel bundle and IGP does not advertise the
tunnel as a link.
