Usage guidelines
This command applies only to an ABR.
When you specify an ACL, follow these guidelines:
•
If a rule in the specified ACL is applied to a VPN instance, the rule does not take effect.
•
If a rule in the specified ACL is not applied to any VPN instance, the rule takes effect on both
VPN packets and public-network packets.

# Use IP prefix list my-prefix-list to filter inbound Type-3 LSAs. Use basic ACL 2000 to filter
outbound Type-3 LSAs in OSPF Area 1.
