Configure SPBM Inter-VSN Routing
Before you begin
-
You must configure the required SPBM and IS-IS infrastructure.
About this task
Configure Inter-VSN routing to route between IP networks on Layer 2 VLANs with different I-SIDs. Inter-VSN routing is typically used only when you have to extend a VLAN as a Layer 2 Virtual Services Network (VSN) for applications such as vMotion. As a best practice, use IP Shortcuts or Layer 3 VSNs to route traffic. You must configure both the Backbone Edge Bridges (BEBs) and the Backbone Core Bridge (BCB). This procedure includes the steps for both roles.
To enable inter-VSN routing, you must configure an IP interface where the routing instance exists.
Procedure
Variable Definitions
The following table defines parameters for the vlan create command.
Variable |
Value |
---|---|
<2-4059> |
Specifies the VLAN ID in the range of 2 to 4059. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1. By default, the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. |
type port-mstprstp <0–63> [color <0–32> ] |
Creates a VLAN by port:
|
The following table defines parameters for the vlan members add command.
Variable |
Value |
---|---|
<1-4059> |
Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1. |
{slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]} |
Identifies the
slot and port in one of the following formats:
|
The following table defines parameters for the vlan i-sid command.
Variable |
Value |
---|---|
<1-4059> |
Specifies the primary VLAN ID. Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1. |
<0-16777215> |
Specifies the service instance identifier (I-SID). You cannot use I-SID 0x00ffffff. The system reserves this I-SID to advertise the virtual BMAC in an SMLT dual-homing environment. This value is the same for the primary and secondary VLANs. Note:
When you add or remove an I-SID on a VLAN IP interface for 5520 Series5720 Series, the switch disables and enables routing on the VLAN interface. |
force |
Specifies the software must replace the existing VLAN-to-I-SID mapping, if one exists. |
The following table defines parameters for the ip vrf command.
Variable |
Value |
---|---|
WORD <1–16> |
Create the VRF and specify the name of the VRF instance. |
vrfid <1–511> |
Specifies the VRF instance by number. |
The following table defines parameters for the vrf command.
Variable |
Value |
---|---|
WORD <1–16> |
Specifies the VRF name. Associates a port to a VRF. |
The following table defines parameters for the ip address command.
Variable |
Value |
---|---|
{A.B.C.D/X} |
Configures an IP address for the VLAN. |
