OmniSwitch AOS Release 6 Network Configuration Guide

• AAA RADIUS servers can be configured on any VRF instance including the default VRF instance. 

However, all of the RADIUS servers must reside on the same VRF instance. 

• The VRF instance that the RADIUS server is configured on becomes the “management” VRF instance 

and can perform authentication for any of the following services:

• If the VRF instance that the RADIUS servers reside on is deleted or disabled, access to the RADIUS 

servers will be disabled as well.

• Each BGPv4 routing instance requires configuration of an Autonomous System number, router ID 

number, and primary IP address that is explicit to the associated VRF instance.

• BGP neighbors defined for a specific VRF instance and address family (IPv4 and IPv6) will peer with 

neighbors accessible through interfaces associated with the same VRF instance.

Tunnel endpoint addresses always exist in the default VRF instance regardless of the instance in which the 
tunnel interface is configured.

• Telnet and SSH (ssh, sftp, and scp) sessions “to” the switch are now VRF aware. Client support for 

these utilities is supported only in the default VRF instance.

• A maximum of 4 combined Telnet sessions are allowed simultaneously across all VRFs on the switch.

• A maximum of 8 combined SSH sessions are allowed simultaneously across all VRFs on the switch

• The Auto-NMS feature (non-VRF aware) recognizes all of the IP interfaces configured in the default 

VRF instance. The first eight of these interfaces are prioritized by Auto-NMS to ensure switch manage-
ability in the event of a DoS attack.

• Policy Based Routing, as indicated in the table above, is a default VRF application. The functionality 

of this feature remains the same as in releases prior to the implementation of Multiple VRF instances.

• A VRF policy condition parameter is available to specify a VRF name to which the policy condition 

applies. This parameter can also specify the default VRF, and a no form of the command exists to 
remove a VRF condition parameter. For example:
