Black Box LR11xx Series Router Configurations Guide

6.1.6 Secondary Addressing – POP Only

Secondary addressing approaches rely on configuring the POP router with a secondary Ethernet address for each remote site. The
POP-only approach uses secondary addresses at the POP while the remote router utilizes only a primary address.

Table 8 POP Only Secondary Addressing

6.1.7 Secondary Addressing – 30 Bit

This approach relies on configuring the POP router with a secondary Ethernet address for each remote site. The remote router is also
configured with a secondary address in that same subnet. The 30-bit approach uses reserved addresses for bundle addressing. The
router primary and the directly connected Black Box reside in a different 30-bit subnet.
