Configuration task list
To establish an MPLS TE tunnel by using a dynamic CRLSP:
Tasks at a glance
(Required.) Configuring MPLS TE attributes for a link
(Required.) Advertising link TE attributes by using IGP TE extension
(Required.) Configuring MPLS TE tunnel constraints
(Required.) Establishing an MPLS TE tunnel by using RSVP-TE
(Optional.) Controlling CRLSP path selection
(Optional.) Controlling MPLS TE tunnel setup
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 Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view. interface interface-type interface-number N/A
3. Configure the maximum
link bandwidth for MPLS
TE traffic.
mpls te max-link-bandwidth
bandwidth-value
By default, the maximum link
bandwidth for MPLS TE traffic
is 0.
4. Configure the maximum
reservable bandwidth.
• 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 ]
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.
