Route retraction for SteelHead SD
7. Optionally, include any notes that will help identify this static route.
8. Click Submit .
SCM sends the static route configuration to the gateway. The static route appears in the Static Routes
page and adds the event to the Event Log.
Note: If a static route is configured on a gateway that is a partner in a high availability pair, SCM sends the static route
information to the partner as well as sending the configuration to the gateway.
Route retraction for SteelHead SD
SteelHead SD advertises available routes and doesn’t advertise unavailable routes. If a route becomes
unavailable, route retraction withdraws this route and ensures it is no longer advertised.
Note: The behavior of route attraction and retraction is the same across all SteelConnect appliances.
To benefit from route retraction on a SteelHead SD, you need to meet the following requirements:
• You need to redistribute the overlay network into the internet gateway protocol on the LAN.
• For SteelHead SD appliances deployed in HA mode, you need to redistribute the overlay network
and connected routes into iBGP.
Note: In SteelConnect 2.12, you might not want to redistribute overlay networks into iBGP because both HA
appliances will be aware of overlay routes, but you should still redistribute connected routes.
To redistribute the overlay into the internet gateway protocol on the LAN
1. In SCM, choose Routing > OSPF.
2. Select your OSPF network to edit the settings.
3. In the Redistribute settings tab, click On for Overlay to OSPF, and click On for Connected to OSPF.
4. Click Submit .
To redistribute the overlay and connected routes into iBGP
1. In SCM, choose Appliances > Overview.
2. Select the site.
3. Open the BGP tab and click On for Overlay to BGP and click On for Connected to BGP.
