A request arrived on your MPLS-vpn-bgp group. Due to a security breach, your customer is experiencing DoS attacks coming from specific subnets (200.0.10.0/24, 200.0.12.0/24). You have checked all MPLS-EBGP routes being advertised to BHK from other VPN sites and found four subnets listed:
200.0.10.0/24, 200.0.11.0/24, 200.0.12.0/24, 200.0.13.0/24. You immediately apply an outbound ACL filter using the appropriate MPLS-EBGP tool: access-list 1 deny 0.0.0.0 255.255.254.255 access-list 1 permit any What happens when you apply this ACL on the MPLS-EBGP connection to BHK?
