Management communication setup
ES-ES communication
Within a cluster the ES-ES, ES-IS, and IS-IS communication is still possible. There is
however no communication possible between nodes in different clusters. For example a
Craft Interface Terminal (CIT) can be connected to a node in a cluster for maintenance
activities on nodes within a cluster. However, it is then not possible to do a remote
login from this node to a node of another cluster.
Management system connections
The management system connected to the 10BaseT can still communicate with all
nodes in the clusters since the ES-IS protocol on the 10BaseT is not disabled.
Important to notice is that the nodes in a Remote Cluster lose their association with the
management system when NO-IS-IS is chosen on the gateway node of the remote
cluster. It is advised to connect the management system to the 10BaseT that connects
the clusters to each other and to assign NO-IS-IS only to nodes on this LAN.
IS-IS area divided DCN
The division of the DCN in areas by introducing Level 2 Intermediate Systems is
similar to disabling the IS-IS protocol over the 10BaseT port of nodes, as described
earlier.
Similar to clustering, the exchange of Level 1 LSPs between Intermediate Systems in
different areas is prevented. However Level 2 LSPs are still exchanged between Level
2 Intermediate Systems.
