Feature Notes : By default Route Monitoring is disabled on the Mobility Access Switch
In a branch deployments need to detect L3 failure when L2 is still up; dynamic routes are taken care by the respective protocols and static routes needs a mechanism to detect the L3 failure and update routing table accordingly. Route Monitoring provides an ability to remove a route based upon probe status. In addition to basic route monitoring feature, it also brings in multiple default gateway support. Route Monitoring enables the MAS to monitor the L3 uplink status using ping probe.
Configure a probe profile
- You can associate only one probe-profile per VLAN interface.
- You can associate the same probe-profile for multiple VLAN interfaces.
- You can configure up to four probe-profiles on the Mobility Access Switch.
- You can configure up to two IP addresses and two ulr’s in a probe-profile. When there are multiple hosts, probe status of the interface is changed to up if ping succeeds to at least one of the configured hosts.
Default-gateway import dhcp
Use the following command to view the configuration on a probe-profile:
(host) #show probe-profile
(host) #show trace routing
