This example does not include the steps for how to create an iBGP session. See
Create an iBGP Connection with a Loopback Interface
configuration.
The following is the route table when no prefix list is configured.
(Netgear Switch) (Config-router)#show ip route
Route Codes: R - RIP Derived, O - OSPF Derived, C - Connected, S - Static
B - BGP Derived, IA - OSPF Inter Area
E1 - OSPF External Type 1, E2 - OSPF External Type 2
N1 - OSPF NSSA External Type 1, N2 - OSPF NSSA External Type 2
C 192.168.1.0/24 [0/1] directly connected,
B 136.1.1.0/24 [200/0] via 192.168.1.2,
B 136.1.2.0/24 [200/0] via 192.168.1.2,
B 136.1.3.0/24 [200/0] via 192.168.1.2,
B 172.222.1.0/24 [200/0] via 192.168.3.1,
B 172.222.2.0/24 [200/0] via 192.168.3.1,
C 192.168.3.0/24 [0/1] directly connected,
Create a prefix list and apply it to BGP to permit 136.1.1.0/24 only and deny all other routes
from any iBGP neighbor.
(Netgear Switch) (Config)#ip prefix-list prefix1 permit 136.1.1.0/24
(Netgear Switch) (Config)#router bgp 100
(Netgear Switch) (Config-router)# distribute-list prefix prefix1 in
The following is the IP route table after prefix1 is configured in BGP. Only 136.1.1.0/24
appears in the table and all of the other routes that were exchanged from Switches B and C
are removed.
(Netgear Switch) (Config-router)#show ip route
Route Codes: R - RIP Derived, O - OSPF Derived, C - Connected, S - Static
B - BGP Derived, IA - OSPF Inter Area
E1 - OSPF External Type 1, E2 - OSPF External Type 2
N1 - OSPF NSSA External Type 1, N2 - OSPF NSSA External Type 2
C 192.168.1.0/24 [0/1] directly connected,
B 136.1.1.0/24 [200/0] via 192.168.1.2,
C 192.168.3.0/24 [0/1] directly connected,
