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

POP Router	e0:	200.1.1.1/30 primary
		199.1.1.1/29 secondary

	wan2:	10.1.2.1/24

Router 2	e0:	199.1.1.11/29
Router/DSU	s0:	199.1.1.18/29

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.
