Configuring Mpls Te Attributes For A Link; Advertising Link Te Attributes By Using Igp Te Extension - HP FlexNetwork 10500 Series Configuration Manual

Configuring MPLS TE attributes for a link

MPLS TE attributes for a link include the maximum link bandwidth, the maximum reservable
bandwidth, and the link attribute.
Perform this task on each interface that the MPLS TE tunnel traverses.
To configure the link TE attributes:
Step
1. Enter system view.
2. Enter interface view.
3. Set the maximum link
bandwidth for MPLS TE
traffic.
4. Set the maximum
reservable bandwidth.
5. Set the link attribute.

Advertising link TE attributes by using IGP TE extension

Both OSPF and IS-IS are extended to advertise link TE attributes. The extensions are called OSPF
TE and IS-IS TE. If both OSPF TE and IS-IS TE are available, OSPF TE takes precedence.
Configuring OSPF TE
OSPF TE uses Type-10 opaque LSAs to carry the TE attributes for a link. Before you configure
OSPF TE, you must enable opaque LSA advertisement and reception by using the
opaque-capability enable command. For more information about opaque LSA advertisement and
reception, see Layer 3—IP Routing Configuration Guide.
MPLS TE cannot reserve resources and distribute labels for an OSPF virtual link, and cannot
establish a CRLSP through an OSPF virtual link. Therefore, make sure no virtual link exists in an
OSPF area before you configure MPLS TE.
To configure OSPF TE:
Command
system-view
interface interface-type interface-number
mpls te max-link-bandwidth
bandwidth-value
•
Configure the maximum reservable
bandwidth of the link (BC 0) and BC 1
in RDM model of the prestandard
DS-TE:
mpls te max-reservable-bandwidth
bandwidth-value [ bc1
bc1-bandwidth ]
•
Configure the maximum reservable
bandwidth of the link and the BCs in
MAM model of the IETF DS-TE:
mpls te max-reservable-bandwidth
mam bandwidth-value { bc0
bc0-bandwidth | bc1 bc1-bandwidth |
bc2 bc2-bandwidth | bc3
bc3-bandwidth } *
•
Configure the maximum reservable
bandwidth of the link and the BCs in
RDM model of the IETF DS-TE:
mpls te max-reservable-bandwidth
rdm bandwidth-value [ bc1
bc1-bandwidth ] [ bc2 bc2-bandwidth ]
[ bc3 bc3-bandwidth ]
mpls te link-attribute attribute-value
86
Remarks
N/A
N/A
By default, the maximum link
bandwidth for MPLS TE
traffic is 0.
Use one command according
to the DS-TE mode and BC
model configured in
"Configuring DS-TE."
By default, the maximum
reservable bandwidth of a
link is 0 kbps and each BC is
0 kbps.
In RDM model, BC 0 is the
maximum reservable
bandwidth of a link.
By default, the link attribute
value is 0x00000000.
