topology site

<site-name>	Site name: for example, data center.
local	Specifies the local site name, which is where the SteelHead is located.
default-site	Specifies the default site, which is the match anything, catch-all site that is used if nothing else matches. This site has a subnet of 0.0.0.0/0. You do not need to add a remote site if you only have one remote site and the default site is suitable. The default site cannot be removed. You cannot add a new area or a new subnet to an existing area for the default site.
out-qos-profile <profile-name>	Specifies the QoS profile name for outbound QoS. These parameters link the outbound QoS configuration to the site to fine-tune the QoS behavior for the site. QoS profiles in RiOS 9.0 replace QoS service policies in previous versions. A QoS profile is a reusable set of QoS rules and classes.
in-qos-profile <profile-name>	Specifies the QoS profile name for inbound QoS. These parameters link the inbound QoS configuration to the site to fine-tune the QoS behavior for the site. QoS profiles in RiOS 9.0 replace QoS service policies in previous versions. A QoS profile is a reusable set of QoS rules and classes.

A site is a collection of resources that share one or more common WAN links, usually in one physical location. Each peer has one local site that is automatically created and cannot be deleted. A QoS profile for a site is used for all networks connected to the site.

RiOS 9.0 determines the destination site using a longest-prefix match on the site subnets. For example, if you define site 1 with 10.0.0.0/8 and site 2 with 10.1.0.0/16, then traffic to 10.1.1.1 matches site 2, not site 1. Consequently, the default site defined as 0.0.0.0 only matches traffic that does not match any other site subnets. This is in contrast to RiOS 8.6 and earlier, where you configured sites in an explicit order and the first-matching subnet indicated a match for that site.
