User Virtual Routers

User VRs are the VRs created by users in addition to the system VRs, and each user VR supports Layer 3 routing and forwarding.

The routing tables for each VR are separate from the tables for other VRs, so user VRs can support overlapping address space.

Note

User VRs are supported only on the platforms listed for the VR feature in the Switch Engine 32.3 Feature License Requirements document. When a SummitStack contains switches that do not support user VRs, the ports on those devices cannot be added to a user VR.

When a new user VR is created, by default, no ports are assigned, no VLAN interface is created, and no support for any routing protocols is added. User VRs support all switch routing protocols. When you add a protocol to a user VR, the user VR starts a process for that protocol. The ExtremeXOS software supports up to 63 user VRs, each of which supports protocols for that VR and all child Virtual Routers and Forwarding instances (VRFs).

Note

When using SNMPv2c for user created virtual router, "read community" in the SNMP tool should be set as "vr_name@community_name" where vr-name is user created virtual router name . Similarly for SNMPv3, "Context name" in SNMP tool should be set as "vr_name@community_name" where vr-name is user created virtual router name .
