Tunnel Rebuild interval(s)—You can configure the interval at which the tunnel is rebuilt. The
valid range is from 1 to 4294967295.
CSPF Method—You can configure the arbitrage policy of the current tunnel, which is used for
path calculation.
Route Fixing—If a route is fixed, the path information cannot be changed.
Tunnel Reoptimization—Dynamic CR-LSP optimization involves periodic calculation of paths
that traffic trunks should traverse. If a better route is found for an existing CR-LSP, a new CR-LSP
is established to replace the old one, and services are switched to the new CR-LSP. You can
enable reoptimization for the MPLS TE tunnel.
Auto Bandwidth Adjustment—As data traffic increases or decreases due to the size and type
of data being transmitted, you can enable the Auto Bandwidth Adjustment functionality to
optimize bandwidth usage and thereby improves bandwidth efficiency.
Auto Bandwidth Adjustment Lower Threshold (Kbps)—The valid range is 1 to 32000000.
Bandwidth Collection Lower Threshold (Kbps)—After the bandwidth of links regulated by MPLS
TE changes, CSPF may need to recalculate paths. This tends to be resource consuming as
recalculation involves IGP flooding. To reduce recalculations and flood only significant
changes, you may configure the bandwidth collection lower threshold. The valid range is 1 to
32000000.
d. Configure the parameters as needed, and then click OK. This tunnel appears in the MPLS TE
Tunnel Query List section of the page.
Managing MPLS TE tunnels
You can query, delete, refresh, modify, and view the network topology of an MPLS TE tunnel that you
have created. You can also view detailed information about the ingress device and the MPLS TE tunnel.
Querying for an MPLS TE tunnel
Over time, the MPLS TE Tunnel query list can grow large, making it more difficult for you to find an MPLS
TE tunnel at a glance. The Query capability enables you to search for MPLS TE tunnels by query type and
its corresponding value.
To query for an MPLS TE tunnel:
1. Click Service > MPLS TE Manager > MPLS TE Tunnel Mng from the tabular navigation system on the
top of the IMC main page.
2. In the MPLS TE Tunnel Query section of the page, select Tunnel Name, Protocol or Tunnel Status
from the Query Type list, specify the corresponding value in the Value field, and then click Query.
MPLS TE tunnels that match these descriptions appear in the MPLS TE Tunnel Query List section of
the page.
Deleting an MPLS TE tunnel
To delete an MPLS TE tunnel:
