JUNI-RT-000290 - The Juniper perimeter router must be configured to not be a Border Gateway Protocol (BGP) peer to an alternate gateway service provider - BGP peer to an alternate gateway service provider.

Information

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.

Solution

This requirement is not applicable for the DoDIN Backbone.

Configure a static route on the perimeter router to reach the AS of a router connecting to an alternate gateway as shown in the example below.

[edit routing-options]
set static route 0.0.0.0/0 next-hop x.x.x.x
