Fix Recommendation

This requirement is not applicable for the DODIN Backbone.

Ensure that a dedicated circuit, MPLS/VPN service, or IPsec tunnel is deployed to transport management traffic between the managed network and the NOC.

Create a VPRN/L3 VPN service for management traffic, as shown in the example below:

- configure service vprn 30 customer 1 create
- config>service>vprn# router-id 3.3.3.3
- config>service>vprn# autonomous-system 65100
- config>service>vprn# interface "management-network" create
- config>service>vprn>if# address 172.x.x.x/30
- config>service>vprn>if# sap 1/1/c3/1 create
- config>service>vprn>if>sap# exit
- config>service>vprn>if# exit
- config>service>vprn# bgp-ipvpn

- config>service>vprn>bgp-ipvpn>mpls# auto-bind-tunnel
- config>service>vprn>bgp-ipvpn>mpls>auto-bind-tunnel# resolution any
- config>service>vprn>bgp-ipvpn>mpls>auto-bind-tunnel# exit
- config>service>vprn>bgp-ipvpn>mpls# route-distinguisher x.x.x.x:x
- config>service>vprn>bgp-ipvpn>mpls# vrf-target target:x:x
- config>service>vprn>bgp-ipvpn>mpls# no shutdown
- config>service>vprn>bgp-ipvpn>mpls# exit
- config>service>vprn>bgp-ipvpn# exit
- config>service>vprn# no shutdown
- config>service>vprn#

Check Contents

This requirement is not applicable for the DODIN Backbone.

Review the network topology diagram to determine connectivity between the managed network and the NOC.

Review the OOBM gateway router configuration to validate the path and interface that the management traffic traverses.

Verify that only the routes and interfaces belonging to the management VPRN are present, as shown in the example below:

- show router 30 route-table

If management traffic is not transported between the managed network and the NOC via dedicated circuit, MPLS/VPN service, or IPsec tunnel, this is a finding.
