Configuring Static Routing Support

Static routing support using enhanced object tracking provides the ability for the switch to use ICMP pings to identify
when a preconfigured static route or a DHCP route goes down. When tracking is enabled, the system tracks the state of
the route and informs the client when that state changes. Static route object tracking uses Cisco IP SLAs to generate
ICMP pings to monitor the state of the connection to the primary gateway.

You use this process to configure static route object tracking:
1. Configure a primary interface for static routing or for DHCP.
2. Configure an IP SLAs agent to ping an IP address using a primary interface and a track object to monitor the state
of the agent.
3. Configure a default static default route using a secondary interface. This route is used only if the primary route is
removed.

Configuring a Primary Interface

Beginning in privileged EXEC mode, follow these steps to configure a primary interface for static routing:
Command
1. configure terminal
2. interface interface-id
3. description string
4. ip address ip-address mask [secondary]
5. exit
Beginning in privileged EXEC mode, follow these steps to configure a primary interface for DHCP:
Command
1. configure terminal
2. interface interface-id
3. description string
4. ip dhcp client route track number
5. ip address dhcp
6. exit
