1524 ExtremeWare 7.7 Command Reference Guide
ESRP Commands
configure vlan add track-rip
configure vlan <vlan name> add track-rip failover <priority>
Description
Configures an ESRP-enabled VLAN to track any available RIP route.
Syntax Description
Default
No RIP route tracking.
Usage Guidelines
If no RIP routes are detected, the ESRP VLAN priority steps to the failover-priority value specified. By
setting the failover priority to be lower than the normal priority of the VLAN, it will cause the affected
VLAN to go into standby.
The range of the priority value is 0 to 254. Setting the priority to 255 configures the switch to slave
mode, and to be ineligible to become the master. The switch will remain in slave mode even when the
VLAN fails over from the current master.
To make effective use of this feature, the following should be true:
• The priority field should be given precedence over the other election factors by assigning the
priority-ports-track-mac
election algorithm to the VLAN.
• The normal priority of the ESRP-enabled VLANs must be higher than the failover priority of this
command.
Example
The following command enables RIP route tracking, and specifies that the ESRP priority for VLAN
esrp-1 be set to 10 upon a diagnostic failure:
configure vlan esrp-1 add track-rip failover 10
