Configure an Interarea Tunnel: Example
The following configuration example shows how to configure a traffic engineering interarea tunnel. Router
R1 is the headend for tunnel1, and router R2 (20.0.0.20) is the tailend. Tunnel1 is configured with a path
option that is loosely routed through Ra and Rb.
Specifying the tunnel tailend in the loosely routed path is optional.Note
configure
interface Tunnel-te1
ipv4 unnumbered Loopback0
destination 192.168.20.20
signalled-bandwidth 300
path-option 1 explicit name path-tunnel1
explicit-path name path-tunnel1
index 10 next-address loose ipv4 unicast 192.168.40.40
index 20 next-address loose ipv4 unicast 192.168.60.60
index 30 next-address loose ipv4 unicast 192.168.20.20
The following configuration example shows how to configure loose-path retry period (range is 30 to 600
seconds) on headend router.
config
mpls traffic-eng
timers loose-path retry-period 120
The following configuration example shows the global configuration for loose hop expansion affinity or metric
on ABR.
config
mpls traffic-eng path-selection loose-expansion affinity 0xff
mpls traffic-eng path-selection loose-expansion metric te class-type 5
Configure Forwarding Adjacency: Example
The following configuration example shows how to configure an MPLS-TE forwarding adjacency on tunnel-te
68 with a holdtime value of 60:
configure
interface tunnel-te 68
forwarding-adjacency holdtime 60
