INT2 INT3 EXT3 | IBM L2/3 guide

Complete configuration snapshots

Example 7-27and Example 7-28 on page 122 show complete configuration files for the GbESM and upstream Core switches. One configuration for each type of switch is shown with notes where the second switch of the same type has a different configuration.
