R3303-HP HSR6800 Routers Layer 3 - IP Routing Configuration Guide

115
The output shows that when an active/standby switchover occurs on Router S, the neighbor
relationships and routing information on Router A and Router B have not changed and the traffic
from Router A to Router B has not been impacted.
Configuring route filtering
Network requirements
• In Figure 31, all the routers in the network run OSPF. The AS is divided into three areas.
• Router A works as the ABR between Area 0 and Area 1. Router B works as the ABR between Area
0 and Area 2.
• Configure Router C as an ASBR to redistribute external routes (static routes), and configure a filter
policy on Router C to filter out route 3.1.3.0/24.
• Configure a routing policy on Router A to filter route 10.5.1.0/24.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure OSPF basic functions (see "Configuring OSPF basic functions").
3. Configure OSPF to redistribute routes:
# On Router C, configure a static route destined for network 3.1.1.0/24.
<RouterC> system-view
[RouterC] ip route-static 3.1.1.0 24 10.4.1.2
# On Router C, configure a static route destined for network 3.1.2.0/24.
[RouterC] ip route-static 3.1.2.0 24 10.4.1.2
# On Router C, configure a static route destined for network 3.1.3.0/24.
[RouterC] ip route-static 3.1.3.0 24 10.4.1.2
# Configure OSPF to redistribute static routes on Router C.
[RouterC] ospf 1
[RouterC-ospf-1] import-route static
[RouterC-ospf-1] quit
# Display the OSPF routing table of Router A.
<RouterA> display ip routing-table
