Secondary Addressing: 30 Bit; Secondary Addressing: 29 Bit - Avaya 1000 Series Configuration Manual

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 Secure Router reside in a different 30-bit subnet.

Secondary Addressing: 29 Bit

This approach utilizes a 29-bit subnet for each remote connection. Within each 29-bit subnet
is the POP router secondary, the Secure Router WAN addressing, and the remote router
secondary.
