3.4 Policy Routing Configuration Example

3.4.1 Configuration Example

I. Network requirements

In the network shown in Figure 3-1:

z An LPU is installed in slot 5 of the switch.

z The IP address of Host 1 is 1.0.0.1, and that of Host 2 is 2.0.0.1.

z Set the next hops of packets sourced from Host 1 to 2.0.0.1.

Caution:

Make sure the VLAN interfaces of GE2/0/1 and GE2/0/2 are on the same network

segments of Host 1 and Host 2 respectively.

III. Configuration procedure

1) Define an ACL for packets source from PC1.

# Create ACL 2000 and enter its view.

<H3C S7500>system-view

[H3C S7500] acl number 2000

# Define a rule to permit packets sourced from Host 1.

[H3C S7500-acl-basic-2000] rule 0 permit source 1.0.0.1 0

[H3C S7500-acl-basic-2000] quit

2) Set the next hop for packets sourced from Host 1.

# Set the next hop of all packets sourced from Host 1 to 2.0.0.1.
