Chapter 34 Configuring MPLS, MPLS VPN, MPLS OAM, and EoMPLS
Configuring MPLS Traffic Engineering and Fast Reroute
Enter the no ip rsvp signalling hello global configuration command to disable Hello signalling on the
switch. Enter the no ip rsvp signalling hello fast-reroute refresh misses or the no ip rsvp signalling
hello fast-reroute refresh interval interface configuration command to set the misses or refresh interval
to the default.
Configuring Primary and Backup Autotunnels
The Autotunnel Primary and Backup feature enables a router to dynamically build backup tunnels and
to dynamically create one-hop primary tunnels on all interfaces configured for MPLS TE. For
information about the commands for MPLS autotunnel, see this URL:
http://www.cisco.com/en/US/docs/ios/mpls/command/reference/mp_book.html
Beginning in privileged EXEC mode, follow these steps to automatically create primary tunnels to all
next hop neighbors:
Step 8
show ip rsvp fast-reroute
show ip rsvp hello instance summary
Verify the configuration.
Step 9
copy running-config startup-config
(Optional) Save your entries in the configuration file.

Step 1
configure terminal
Enter global configuration mode.
Step 2
mpls traffic-eng auto-tunnel primary
onehop
Configure the switch to automatically create primary MPLS tunnels
to all next hops.
Step 3
mpls traffic-eng auto-tunnel primary
tunnel-num [min num] [max num]
Configure the range of tunnel interface numbers for primary
autotunnels.
•
(Optional) [min num]—Specify the minimum number of the
primary tunnels. Valid values are from 0 to 65535. The default
is 65436.
•
(Optional) [max num]—Specify the maximum number of the
primary tunnels. The max number is the minimum number plus
99. Valid values are from 0 to 65535.
Step 4
mpls traffic-eng auto-tunnel primary
timers removal rerouted sec
Configure how many seconds after a failure primary autotunnels are
removed. Valid values are 30 to 604800. The default is 0.
Step 5
mpls traffic-eng auto-tunnel primary
config unnumbered interface-id
Enable IP processing on the specified interface without an explicit
address.
Step 6
mpls traffic-eng auto-tunnel primary
config mpls ip
Enable Label Distribution Protocol (LDP) on primary autotunnels.
Step 7
clear mpls traffic-eng auto-tunnel primary Remove all primary autotunnels and re-create them.
Step 8
end
Return to privileged EXEC mode.
Step 9
show interface tunnel tunnel-num
Verify the configuration.
Step 10
copy running-config startup-config
(Optional) Save your entries in the configuration file.
