| NE type restrictions
Observe the following NE type restrictions: • All NE types, managers, and other OSI nodes (like external OSI routers) are allowed as level 1 IS nodes or as ES-only nodes, in an area with partition repair capable NEs. When a repair tunnel is established, the partition repair designated NEs advertise information such, that the tunnel is identified as a normal level-1 route within the area. • All NE types and other OSI nodes (like external OSI-routers) are allowed as level 2 nodes in the level 2 subdomain, as long as they are not part of the shortest inter-area path between two partition repair capable NEs in an area. The network is expected to be designed for full management connectivity in case of a single failure. In case of two failures, including a partitioned area and a failure in the shortest potential tunnel route, the network is allowed to drop management connections. Therefore not all OSI nodes in the level 2 subdomain need to be partition compatible. Large network restrictions Observe the following restrictions regarding large networks: • The manager connections that are tunnelled through a level 2 node in case of a single failure, are counted as connections and must therefore be subtracted (like all other rerouted connections through this node) from the maximum number as specified in S-111 in order to identify the maximum number of acceptable connections in the case that the network is in its normal (failure-free) state. If 50 manager connections can be tunneled in case of a failure, and 150 manager connections are forwarded in a failure-free network, through one of the nodes in the potential tunnel, the related node must be capable of forwarding 200 manager Management communication setup concepts ................................................................................................................................................................................................................................... 365-312-875R5.2 Issue 1, March 2007 tải về 2.06 Mb.
