Configuring The Routing Protocol For Mpls Te; Configuring Te Fast Reroute - Cisco 3845 - Security Bundle Router Software Manual

Configuring MPLS Traffic Engineering and Fast Reroute
Command
Step 16
exclude-address A.B.C.X
Step 17
end
Step 18
show ip explicit-paths
Step 19
copy running-config startup-config
Enter the no forms of the commands to remove the configured MPLS tunnels. Enter the no ip
explicit-path name global configuration command to disable IP explicit paths.

Configuring the Routing Protocol for MPLS TE

Beginning in privileged EXEC mode, follow these steps to configure IS-IS or OSPF for MPLS traffic
engineering:
Command
Step 1 configure terminal
Step 2 router {isis | ospf}
Step 3 mpls traffic-eng {level-1 | level-2}
or
mpls traffic-eng area 0
Step 4 mpls traffic-eng router-id loopback0
Step 5
metric-style wide
Step 6
end
Step 7
show mpls traffic-eng
show ip ospf mpls traffic-eng
Step 8 copy running-config startup-config
To remove the traffic engineering router identifier, use the no mpls traffic-eng router-id command.

Configuring TE Fast Reroute

Before or after entering the commands described in these procedures, you must enable the MPLS traffic
engineering tunnel capability globally on the tunnel routers by entering the mpls traffic-eng tunnels
global and interface configuration commands. For information about the commands for MPLS TE fast
reroute, see this URL:

Purpose
(Optional) Exclude an address from the IP explicit path.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Enable IS-IS or OSPF routing, and enter router configuration mode.
Turn on MPLS traffic engineering for IS-IS level 1 or level 2.
Turn on MPLS traffic engineering for OSPF.
Specify the traffic engineering router identifier for the node to be the
IP address associated with interface loopback0.
Configure a router to generate and accept only new-style stands for
type, length, and value objects (TLVs).
Note This command is for IS-IS routing only.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
