Policy Routing Configuration
Example
When there are many Internet Service Provider (ISP) egresses on
the network, select different ISP egresses for users from differ-
ent groups through policy routing or select different ISP egresses
based on service types.
As shown in
Figure 21
, Users on both sub-networks are connected
to the switch and there are two available ISP egresses.
It is
required to select different egresses based on IP addresses of
users as follows: Users on the sub-network 10.10.0.0/24 use the
ISP1 egress.
Users on the sub-network 11.11.0.0/24 use the
ISP2 egress.
