Description
ISPs use BGP to share route information with other autonomous systems (i.e., other ISPs and corporate networks). If the perimeter router was configured to BGP peer with an ISP, NIPRNet routes could be advertised to the ISP, thereby creating a backdoor connection from the internet to the NIPRNet.
ℹ️ Check
This requirement is not applicable for the DODIN Backbone. Determine the IP address of the alternate gateway service provider and confirm that the ICX is not configured with that address as a BGP peer. If the ICX is configured with the alternate gateway service provider IP address as a BGP peer, this is a finding.
✔️ Fix
This requirement is not applicable for the DODIN Backbone. Delete the BGP peer statement to the alternate gateway service provider: ICX(config)# router bgp ICX(config-bgp-router)# no neighbor x.x.x.x remote-as yyyy If necessary, configure a default route to the alternate gateway service provider: ICX(config)# ip route 0.0.0.0/0 x.x.x.x
