The route destined for network 3.1.3.0/24 is filtered out.
5. Configure SecPath A to filter out route 10.5.1.1/24:
# Configure the ACL on SecPath A.
<SecPathA> system-view
[SecPathA] acl number 2000
[SecPathA-acl-basic-2000] rule 0 deny source 10.5.1.0 0.0.0.255
[SecPathA-acl-basic-2000] rule 1 permit source any
[SecPathA-acl-basic-2000] quit
# Use the ACL to filter route 10.5.1.0/24.
[SecPathA] ospf 1
[SecPathA-ospf-1] filter-policy 2000 import
[SecPathA-ospf-1] quit
# Display the OSPF routing table of SecPath A.
[SecPathA] display ip routing-table

Configuring BFD for OSPF at the CLI
Network requirements
As shown in Figure 275 :
• OSPF is enabled on SecPath A, Router B and Router C so that they are reachable to each other at
the network layer.
• After the link over which SecPath A and Router B communicate through a Layer 2 switch fails, BFD
can quickly detect the failure and notify OSPF of the failure. SecPath A and Router B then
communicate through Router C.
