Configuring Interface Pbr Based On Packet Length - HPE FlexNetwork HSR6800 Configuration Manual

# Configure interface PBR by applying the policy aaa on GigabitEthernet 2/1/1.
[RouterA] interface GigabitEthernet 2/1/1
[RouterA-GigabitEthernet2/1/1] ip address 10.110.0.10 255.255.255.0

# Configure the IP addresses of the serial interfaces.
[RouterA] interface serial 2/2/0
[RouterA-Serial2/2/0] ip address 1.1.2.1 255.255.255.0
[RouterA-Serial2/2/0] quit
[RouterA] interface serial 2/2/1
[RouterA-Serial2/2/1] ip address 1.1.3.1 255.255.255.0
Configure Router B:
2.
# Configure a static route to subnet 10.110.0.0/24.
<RouterB> system-view
[RouterB] ip route-static 10.110.0.0 24 1.1.2.1
# Configure the IP address of the serial interface.
[RouterB] interface serial 2/2/0
[RouterB-Serial2/2/0] ip address 1.1.2.2 255.255.255.0
Configure Router C:
3.
# Configure a static route to subnet 10.110.0.0/24.
<RouterC> system-view
[RouterC] ip route-static 10.110.0.0 24 1.1.3.1
# Configure the IP address of the serial interface.
[RouterC] interface serial 2/2/1
[RouterC-Serial2/2/1] ip address 1.1.3.2 255.255.255.0
Verify the configuration:
4.
Configure the IP address 10.110.0.20/24 for Host A, and specify its gateway address as
10.110.0.10.
On Host A, Telnet to Router B that is directly connected to Router A. The operation succeeds.
On Host A, Telnet to Router C that is directly connected to Router A. The operation fails.
Ping Router C from Host A. The operation succeeds.
Telnet uses TCP and ping uses ICMP. The preceding results show that all TCP packets
received on GigabitEthernet 2/1/1 of Router A are forwarded through Serial 2/2/0, and other
packets are forwarded through Serial 2/2/1. The interface PBR configuration is effective.

Configuring interface PBR based on packet length

Network requirements
As shown in
GigabitEthernet 2/1/1 of Router A as follows:
•
Forwards packets with a length of 64 to 100 bytes to the next hop 150.1.1.2/24.
•
Forwards packets with a length of 101 to 1000 to the next hop 151.1.1.2/24.
All other packets are forwarded according to the routing table.
