SUMMARY STEPS
1. configure
2. ipv4 unnumbered mpls traffic-eng Loopback N
3. mpls traffic-eng
4. auto-tunnel mesh
5. tunne-id min value max value
6. group group-id
7. onehop
8. Use the commit or end command.
DETAILED STEPS
Command or Action
Step 1 configure
Example:
RP/0/RP0/CPU0:router# configure
Step 2 ipv4 unnumbered mpls traffic-eng Loopback N
Example:
RP/0/RP0/CPU0:router(config)#ipv4 unnumbered mpls
traffic-eng loopback 0
Step 3 mpls traffic-eng
Example:
RP/0/RP0/CPU0:router(config)#mpls traffic-eng
Step 4
auto-tunnel mesh
Example:
RP/0/RP0/CPU0:router(config-mpls-te)#auto-tunnel
mesh
Step 5 tunne-id min value max value
Example:
RP/0/0/CPU0:ios(config-te-auto-mesh)# tunnel-id
min 4000 max 6000
Step 6 group group-id
Example:
RP/0/RP0/CPU0:router(config-te-auto-mesh)#group

Enabling Auto-onehop Tunnels to Next-hop Neighbors
Purpose
Enters global configuration mode.
Configures the globally configured IPv4 address that can
be used by the Auto-tunnel backup tunnels.
Enters the MPLS-TE submode.
Enters the auto-tunnel mesh configuration submode.
Specifies the minimum and maximum number of
auto-tunnel mesh tunnels that can be created on this router.
The range of tunnel ID is from 0 to 65535.
Enters the auto-tunnel mesh group configuration submode
and creates a group ID.
