Information
If the static routes to the alternate gateway are being redistributed into an Exterior Gateway Protocol or Interior Gateway Protocol to a NIPRNet gateway, this could make traffic on NIPRNet flow to that particular router and not to the internet Access Point routers. This could not only wreak havoc with traffic flows on NIPRNet, but it could overwhelm the connection from the router to the NIPRNet gateway(s) and also cause traffic destined for outside of NIPRNet to bypass the defenses of the internet Access Points.
Solution
This requirement is not applicable for the DODIN backbone.
Configure the router so static routes are not redistributed to an alternate gateway into either an Exterior Gateway Protocol or Interior Gateway Protocol to the NIPRNet or to other autonomous systems.
Review the BGP and IGP configurations and remove the redistribute static statement if it is configured.
BGP Example:
router bgp 1500
no redistribute static
OSPF Example:
router ospf 1500
no redistribute static
RIP Example:
router rip
no redistribute static
