Working mode
Tunnel bundle interface operating modes:
• Load Balancing.
• 1+1—1+1 protection switching mode.
• 1:1—1:1 protection switching mode.
For more information about 1+1 and 1:1 protection switching
modes, see MPLS Configuration Guide.
Tunnel type This field supports only CRLSP.
Tunnel destination Destination address for the tunnel bundle interface.
Load-share Weight of the interface for load sharing.
ds-te bc-model
Use ds-te bc-model to specify the bandwidth constraint (BC) model used in IETF DS-TE.
Use undo ds-te bc-model to restore the default.
Syntax
ds-te bc-model mam
undo ds-te bc-model
Default
The BC model of IETF DS-TE is Russian Dolls Model (RDM).

Parameters
mam: Specifies the BC model as Maximum Allocation Model (MAM).
Usage guidelines
RDM does not define the bandwidth for one class type (CT) but limits the shared bandwidth for multiple
CTs. In cooperation with priority preemption, the RDM model can also implement the isolation between
CTs, ensuring each CT its share of bandwidth. RDM is suitable for networks where traffic is unstable and
traffic bursts might occur.
MAM constrains the bandwidth for only one CT on an interface. This ensures isolation between CTs no
matter whether preemption is used or not. Compared with RDM, MAM is easy to understand and
configure. MAM is suitable for networks where traffic of each CT is stable.
This command applies only to IETF DS-TE. The prestandard DS-TE only uses RDM.
After you change the BC model in IETF DS-TE mode, all nonzero-bandwidth CRLSPs on the device are
deleted and then reestablished.
