6. In the Advertise Lifetime field, enter the value (in seconds) to be used as the lifetime field

Configuring and Viewing Routes
From the Routing Table page, you can configure static and default routes and view the
routes that the GS748T has already learned.
To display the page click the Rou
ting Routing Table link.
To configure a route:
1. In the Route
Type field, specify whether the route is to be a Default route or a Static
route. If creating a default route, you need to specify only the next hop IP address;
otherwise, you need to specify each field.
2. In
the Network Address field, specify the IP route prefix for the destination. To create a
route, a valid routing interface must exist and the next hop IP Address must be on the same
network as the routing interface.
3. In
the Subnet Mask field, specify the network mask to indicate the portion of the IP address
that identifies the attached network.
