mpls te tie-breaking
Use mpls te tie-breaking to specify a tie breaker that a tunnel uses to select a path when multiple paths
with the same metric are present.
Use undo mpls te tie-breaking to restore the default.
Syntax
mpls te tie-breaking { least-fill | most-fill | random }
undo mpls te tie-breaking
Default
In MPLS view, the tie breaker is random.
In tunnel interface view, no tie breaker is specified.
Views
MPLS view, tunnel interface view
Default command level
2: System level
Parameters
least-fill: Selects a path with the least bandwidth usage ratio (the used bandwidth to the maximum
reservable link bandwidth).
most-fill: Selects a path with the most bandwidth usage ratio (the used bandwidth to the maximum
reserved bandwidth).
random: Selects a path randomly.
Usage guidelines
A tunnel prefers the tie breaker specified in the tunnel interface view. If no tie breaker is specified in tunnel
interface view, the tunnel uses the tie breaker specified in MPLS view to select a path.
The IETF DS-TE supports only random path selection.
Examples
# Configure tunnels to use the paths with the least bandwidth usage ratio.
<Sysname> system-view
[Sysname] mpls
[Sysname-mpls] mpls te tie-breaking least-fill
# Configure tunnel 0 to use the path with the least bandwidth usage ratio.
<Sysname> system-view
[Sysname] interface tunnel 0
[Sysname-Tunnel0] mpls te tie-breaking least-fill
mpls te timer auto-bandwidth
Use mpls te timer auto-bandwidth to enable automatic bandwidth adjustment and set the interval for
output rate sampling for tunnels governed by automatic bandwidth adjustment.
Use undo mpls te timer auto-bandwidth to restore the default.
