Use ”path-cost auto” to have the uplink’s path-cost depend on its link
speed and duplex mode. Use ”path-cost COST” to set a static path-cost
for the uplink. ”no path-cost” will reset the path cost to the default setting
(auto).
”show path-cost” will show the configured uplink path-cost.
Default values Auto
15.3.12 Set Multi-Link Dual-Homing Uplink Priority
Syntax [no] priority <1..65535> [adjust <DELTA>]
Context Dual-Homing Uplink Configuration context
Usage Configure uplink priority, and optionally enable sticky uplink election by
setting adjust value.
❼ Use ”priority VALUE” to set priority value. A lower value increases
the chance for this uplink to be elected as active uplink (lower is better).
With equal path-cost (
section 15.3.11 ), an uplink with ”priority 100”
is preferred as uplink over an uplink with ”priority 110”.
❼ Use the optional ”adjust DELTA” setting to improve its priority (i.e.,
lower its priority with the specified ”DELTA”) once the uplink is elected
as active uplink. This gives a sticky uplink behaviour where shifting
active uplink will be less common.
Consider the following example with uplink A (”priority 100”), uplink
B (”priority 110 adjust 20”), and uplink C (”priority 120 adjust
40”), and where uplink A came up first and is the active uplink. If uplink
A goes down, uplink B takes over as it has lower priority than uplink
C (110 < 120). Uplink B will then apply its adjustment and announce
priority to 90 (110 − 20) in its hello messages. Uplink B will stay as
active uplink even if uplink A comes up again (90 < 100).
”show priority” will show the configured uplink priority.
Default values priority 128 (no adjustment)
