Chapter 2 Getting Started

Connecting to another ATM switch which doesn’t support PNNI

If you are attaching another ATM switch that doesn’t support PNNI, you must configure a route to that switch.

For example, if you are connecting a Collage 740 to port 8.5.0 on the M770 ATM Switch, you should configure the static routing table by performing the following steps:

(assume that the partial ATM prefix of the Collage 740 is 39.04)

M15-155s8:/>route add 39.04. 8.5.0

Configuring Hierarchical PNNI

The following steps will help you in configuring your network into a hierarchy of peer groups. You will need a basic knowledge of PNNI.

•Create a drawing of the network you want to achieve while completing the following steps:

1 Decide how many level of hierarchy you need.

2 Divide your switches into different peer groups.

3 Decide how many peer groups are grouped together in to the next level of hierarchy.

4 On each peer group, decide which node will be the Peer Group Leader (PGL). Or better, configure all switches to be capable of becoming a Peer Group Leader (assuming their software version supports this). The PNNI's Peer Group Leader Election protocol will determine the active PGL.

5 Repeat the steps 3 &4, until all peer groups of all switches are organized in the hierarchy.

6 Decide the level scopes of the different level, in the range of 1-104. A lower level should have a greater number.

Note: In the CLI, levels are numbered 1,2,3…. where 1 indicates the lower level (the

physical level in which the node resides), 2 indicates the next level in the hierarchy and so on.

7Determine the switches' prefixes so they will match the organization into peer groups and the specified levels. There is an algorithm that can help you in determining the prefixes to match the hierarchy (see Appendix ).

•Configure all switches' ATM Address prefixes as determine in step 7, and force their node IDs to match the prefix. The configuration is done on the Master Agent using the command:

M15-155s8:/>/address prefix <prefix> node_id
