Detailed Description

The structure describes the ROUTE6 Entry.

There exists an entry for each of the following:-

• Every Network (Prefix List) to which the box is connected These routes are known as CLONING Routes since they can spawn multiple Host Routes (b) below. These routes do -not- have an LLI6 Entry since they map to a network route which is ON LINK

• Every Host on the network to which packets have been sent These routes are typically CLONED routes. These routes always have a matching LLI6 Entry since they this maps a HOST IPv6 Address to an LLI6 Entry.

• Default Routes (Gateway Routes) These routing entries exist for default gateways; the 'IPAddr' in this case is :: and so is the 'IPMask'. The 'NextHop' is the Address of the GATEWAY. These routes are always added to the end of the routing table since they will always match. These routes always have an LLI6 Entry.

Thus currently the Flags supported here are:-

• FLG_RTE_CLONING This identifies (a) above.
• FLG_RTE_HOST This identifies (b) above.
• FLG_RTE_GATEWAY This identifies (c) above.
