Fix Recommendation

Configure the router to use unique keys for each AS that it peers with as shown in the example below:

R1(config)#router bgp xx
R1(config-router)#neighbor x.1.1.9 password yyyyyyyy
R1(config-router)#neighbor x.2.1.7 password zzzzzzzzz

Review the BGP configuration to determine if it is peering with multiple autonomous systems. Interview the ISSM and router administrator to determine if unique keys are being used.

router bgp xx
no synchronization
bgp log-neighbor-changes
neighbor x.1.1.9 remote-as yy
neighbor x.1.1.9 password yyyyyyyy
neighbor x.2.1.7 remote-as zz
neighbor x.2.1.7 password zzzzzzzzz

If unique keys are not being used, this is a finding.
