3. Configure BGP route
reception filtering policies.
• Reference an ACL or IP prefix list
to filter BGP routes received from
all peers:
filter-policy { ipv4-acl-number |
prefix-list prefix-list-name }
import
• Reference a routing policy to filter
BGP routes received from a peer
or peer group:
peer { group-name | ipv4-address
[ mask-length ] } route-policy
route-policy-name import
• Reference an ACL to filter BGP
routes received from a peer or
peer group:
peer { group-name | ipv4-address
[ mask-length ] } filter-policy
ipv4-acl-number import
• Reference an AS path list to filter
BGP routes received from a peer
or peer group:
peer { group-name | ipv4-address
[ mask-length ] } as-path-acl
as-path-acl-number import
• Reference an IPv4 prefix list to
filter BGP routes received from a
peer or peer group:
peer { group-name | ipv4-address
[ mask-length ] } prefix-list
prefix-list-name import
Use at least one method.
