1522 ExtremeWare 7.7 Command Reference Guide
ESRP Commands
configure vlan add track-ospf
configure vlan <vlan name> add track-ospf failover <priority>
Description
Configures an ESRP-enabled VLAN to track any available OSPF route.
Syntax Description
Default
No OSPF route tracking.
Usage Guidelines
The switch cannot be the ESRP master if none of the specified routes are reachable.
If no OSPF 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 normal priority of the ESRP-enabled VLANs must be higher
than the failover priority of this command.
Example
The following command enables OSPF route failure tracking, and specifies that the ESRP priority for
VLAN
esrp-1 be set to 10 when all OSPF routes become unreachable:
configure vlan esrp-1 add track-ospf failover 10
