Advertising Link Te Attributes By Using Igp Te Extension - HP MSR2000 Configuration Manual

Step
4. Configure the maximum
reservable bandwidth.
5. Configure 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- 1 0 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:
Step
1. Enter system view.
2. Enter OSPF view.
3. Enable opaque LSA
advertisement and reception.
Command
•
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
Command
system-view
ospf [ process-id ]
opaque-capability enable
68
Remarks
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.
Remarks

N/A
By default, opaque LSA
advertisement and reception are
enabled.
