Help me to understand such situation. It is necessary translate a little of config from Screenos to Junos.

Screenos issue:

set vrouter "trust-vr"
set route vrouter "TrustGi-vr" preference 20

set vrouter "TrustGi-vr"
set route vrouter "trust-vr" preference 20

I would translate as here. Junos issue:

set routing-instances trust-vr instance-type virtual-router
set routing-instances trust-vr routing-options static route next-table TrustGi-vr.inet.0

set routing-instances TrustGi-vr instance-type virtual-router
set routing-instances TrustGi-vr routing-options static route next-table trust-vr.inet.0

it seems that everything is logical and correct, but the error appears:

[edit routing-instances vrf-trust routing-options static]
root# commit check 
error: [rib vrf-trust.inet.0 routing-options static]
next-table may loop
error: configuration check-out failed

Chance of loops in screenos nobody cared. but in Junos felt that this possibility should be avoided. Tell me how to translate this preferably using Policy-Statements ( not rib-groups).

  • Thank you for asking; I'm curious... is this question addressing the same problem as this one? Mar 10, 2014 at 0:08
  • It's like a sequel...!Yet, Essentially two different questions! In the first case, I just wanted to know whether I translate the configuration correctly??? But the problem with this issue is more complicated. I outlined it, I hope intelligibly!
