Configuring Auto-Tunnel Mesh - Cisco NCS 5500 Series Configuration Manual

Configuring MPLS-TE
Bandwidth Parameters
Overflow threshold
Adjustment threshold
Configuration Example
This example enables automatic bandwidth on MPLS-TE tunnel interface and configure the following automatic
bandwidth variables.
• Application frequency
• Bandwidth limit
• Adjustment threshold
• Overflow detection
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# auto-bw
RP/0/RP0/CPU0:router(config-if-tunte-autobw)# application 1000
RP/0/RP0/CPU0:router(config-if-tunte-autobw)# bw-limit min 30 max 1000
RP/0/RP0/CPU0:router(config-if-tunte-autobw)# adjustment-threshold 50 min 800
RP/0/RP0/CPU0:router(config-if-tunte-autobw)# overflow threshold 100 limit 1
RP/0/RP0/CPU0:router(config)# commit
Verification
Verify the automatic bandwidth configuration using the show mpls traffic-eng tunnels auto-bw brief
command.

Configuring Auto-Tunnel Mesh

The MPLS-TE auto-tunnel mesh (auto-mesh) feature allows you to set up full mesh of TE Point-to-Point
(P2P) tunnels automatically with a minimal set of MPLS traffic engineering configurations. You can configure
one or more mesh-groups and each mesh-group requires a destination-list (IPv4 prefix-list) listing destinations,
which are used as destinations for creating tunnels for that mesh-group.
You can configure MPLS-TE auto-mesh type attribute-sets (templates) and associate them to mesh-groups.
Label Switching Routers (LSRs) can create tunnels using the tunnel properties defined in this attribute-set.
