Prisma Access advertises mobile user routes in
blocks of /24 subnets and
adds BGP community values in the routes it advertises through the
service connection. The following figure shows a mobile user deployment
with three service connections and three different IP address blocks
specified for the
mobile user IP address pool:
192.168.64.0/20
for
the
Asia, Australia & Japan
region,
192.168.72.0/20
for
the
Africa, Europe & Middle East
region,
and
192.168.48.0/20
for the
North
America & South America
region. Prisma Access divides
these routes into block of /24 and advertises them with an Prisma
Access’ AS number of
65534
, but also appends
the BGP community values to the advertisements (
Z
for
Asia,
Y
for EU, and
X
for
US). Those routes are shown in the middle of the figure. In this
way, you can differentiate service connections in your network,
even though Prisma Access assigns the same AS number to them.
