direct-route cost

Function

The direct-route cost command configures a cost for routes to the directly connected network segment on an interface.

The undo direct-route cost command restores the default configuration.

By default, the cost of routes to the directly connected network segment on interfaces is 0.

Usage Guidelines

Usage Scenario

After the direct-route cost command is run on an L3VE sub-interface, the cost of routes to the directly connected network segment on the L3VE sub-interface becomes the configured value. For configurations details, see Configuration-IP Routing Basis Configuration-Configuring AGGs to Load-Balance RNC-to-CSG Traffic.

Precautions

Both the direct-route cost and direct-route track pw-state, direct-route track vrrp, or direct-route degrade-delay commands can be run.

If both the direct-route cost and direct-route track pw-state commands are run, the cost of routes to the directly connected network segment is calculated according to the following rules:
- If the PW is active, the cost is the value configured using the direct-route cost command.
- If the PW is standby or Down, the cost is the value configured using the direct-route cost command plus that configured using the direct-route track pw-state command. If the calculated cost is greater than the maximum value (4294967295), 4294967295 takes effect.
If both the direct-route cost and direct-route track vrrp commands are run, the cost of routes to the directly connected network segment is calculated according to the following rules:
- If the device is the master of the VRRP group, the cost is the value configured using the direct-route cost command.
- If the device is a backup device of the VRRP group, the cost is the value configured using the direct-route cost command plus that configured using the direct-route track vrrp command. If the calculated cost is greater than the maximum value (4294967295), 4294967295 takes effect.
If both the direct-route cost and direct-route degrade-delay commands are run and the L3VE sub-interface goes from Down to Up, the cost of routes to the directly connected network segment is calculated according to the following rules:
- After the delay expires, the cost is the value configured using the direct-route cost command.
- Before the delay expires, the cost is the value configured using the direct-route cost command plus that configured using the direct-route degrade-delay command. If the calculated cost is greater than the maximum value (4294967295), 4294967295 takes effect.

Example

# Set the cost of routes to the directly connected network segment on a sub-interface to 30 when the sub-interface is Up.
