You may perform the mpls te fast-reroute bypass-tunnel command multiple
times to specify multiple bypass tunnels for the protected interface. At present, a
maximum of three bypass tunnels can be specified for a protected interface.
When specifying a bypass tunnel, consider the following:
■ The state of the tunnel must be up.
■ The protected interface is not the outgoing interface in the route entries for the
LSP of the bypass tunnel.
n
■ A bypass tunnel cannot be used for services like VPN at the same time.
■ This command is not supported when the signaling protocol is CR-LDP.
Example # Use Tunnel 0 as the bypass tunnel to protect the link connected to interface
Ethernet 1/0.

mpls te igp advertise
Syntax mpls te igp advertise [ hold-time value ]
undo mpls te igp advertise
View Tunnel interface view
Parameter hold-time value: Sets the delay that IGP waits to notify IGP neighbors of the
down event of the TE tunnel. It ranges from 0 to 4294967295 milliseconds. The
default is 0 milliseconds.
Description Use the
mpls te igp advertise command to enable IGP to advertise the MPLS TE
tunnel as a link to IGP neighbors.
Use the
undo mpls te igp advertise command to remove the configuration.
By default, IGP does not advertise MPLS TE tunnels to IGP neighbors.
n
The mpls te igp advertise command cannot be used together with the mpls te
igp shortcut command.
Example # Set the hold time to 10000 milliseconds.
