BGP LAB 1: BGP Access List Filtering and Answer

2 routers connected with eBGP.  Want to filter some routes (10.x.x.x) from the neighbor router using Extended Access List.

Goal:

Config like diagram.
Configure EBGP between router Tristram and Sanctuary.
Advertise the loopback interfaces on both routers in BGP.
Configure a summary that advertises 10.0.0.0/8 towards router Sanctuary.
Configure an extended access-list on router Sanctuary that will block the 10.0.0.0/8 prefix but allows all other prefixes.
Configure an extended access-list on router Tristram that blocks network 10.2.2.0/24.

Answer:

Tristram Router:

router bgp 1
 no synchronization
 bgp log-neighbor-changes
 network 1.1.1.1 mask 255.255.255.255
 network 10.0.0.0  === Advertise the 10.x network, then need the summary-only next statement.
 aggregate-address 10.0.0.0 255.0.0.0 summary-only  === This is to summarize the 10.x.
 neighbor 192.168.12.2 remote-as 2
 neighbor 192.168.12.2 distribute-list 100 in  ===Deny the ACL 100 from coming in.

access-list 100 deny   ip 10.0.0.0 0.255.255.255 any  === Deny the 10.x network.
access-list 100 permit ip any any


Sanctuary Router:

router bgp 2
 no synchronization
 bgp log-neighbor-changes
 network 2.2.2.2 mask 255.255.255.255
 network 10.2.2.0 mask 255.255.255.0
 aggregate-address 10.0.0.0 255.0.0.0 summary-only
 neighbor 192.168.12.1 remote-as 1
 neighbor 192.168.12.1 soft-reconfiguration inbound
 neighbor 192.168.12.1 distribute-list 100 in

access-list 100 deny   ip 10.0.0.0 0.255.255.255 any
access-list 100 permit ip any any

sh ip bgp nei 192.168.12.1 received-routes
sh ip route
