network (VPN) tunnels. The linked SMB sites described in this guide are
verified for small deployment using BCM50 and larger deployment using
BCM200/400 in the following interconnected reference topologies:
•
"Interconnection of peer sites with incumbent routers (topology 1 with
topology 1)" (page 53)
•
"Interconnection of peer sites using BSR222 (topology 2 with topology
2)" (page 54)
•
"Interconnection of main and remote sites using BSR222 and
BCM200/400 (topology 2 with BCM 200/400)" (page 55)
In main and remote linked site scenarios, the main office hosts a BCM
telephony call server and is linked to remote offices where IP telephony
service is provided from the main office through branch office VPN
tunnels. Generally, these remote sites are very small offices where the
cost of deploying a locally hosted BCM telephony call server cannot be
justified. The linked SMB sites described in this guide are verified for small
deployment using BCM50 and larger deployment using BCM200/400 in the
following interconnected reference topologies:
•
"Interconnection of BSR222 and an incumbent router (topology 1 with
topology 3)" (page 56)
•
"Interconnection of main and remote sites using BSR222 (topology 2
with topology 3)" (page 58)
Third step
After you determine which topology you are configuring, proceed to the
associated section of this guide, as follows:
•
If you are configuring a smaller converged site—mixed vendor
environment, proceed to "Converged small site (mixed-vendor
environment)—reference topology 1" (page 23).
•
If you are configuring a smaller converged site—Greenfield and
infrastructure replacement, proceed to "Smaller converged site
(Greenfield and infrastructure replacement)—reference topology 2"
(page 37).
•
If you are configuring a smaller remote site—Greenfield and
infrastructure replacement, proceed to "Smaller remote site (Greenfield
and infrastructure replacement)—reference topology 3" (page 43).
•
If you are interconnecting multiple sites, proceed to "WAN interconnected
LAN reference topologies" (page 49).
