Configuring BCBs for Inter-VSN Routing
Inter-VSN allows you 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. Use IP Shortcuts to route traffic. You must configure both the Backbone Edge Bridges (BEBs) and the Backbone Core Bridge (BCB).
Note
To enable inter-VSN routing, you must configure the IP interface where the routing instance exists.
Before you begin
-
You must configure the required SPBM and IS-IS infrastructure.
-
You must configure the Backbone Edge Bridges (BEBs) containing the VSNs you want to route traffic between. For more information, see Configure BEBs for Inter-VSN Routing.
About this task
Follow the procedures below to configure the Backbone Core Bridge (BCB) for inter-VSN routing.
Procedure
VRF field descriptions
Use the data in the following table to help you use the VRF tab.
Name |
Description |
---|---|
Id |
Specifies the ID number of the VRF instance. VRF ID 0 is reserved for the GlobalRouter. |
Name |
Names the VRF instance. |
ContextName |
Identifies the VRF. The SNMPv2 Community String or SNMPv3 contextName denotes the VRF context and is used to logically separate the MIB module management. |
TrapEnable |
Enables the VRF to send VRF Lite-related traps (VrfUp and VrfDown). The default is true. |
MaxRoutes |
Configures the maximum number of routes allowed for the VRF. The maximum value varies per platform. See Release Notes for VOSS for platform-specific scaling information. The default value is 10000. |
MaxRoutesTrapEnable |
Enables the generation of the VRF Max Routes Exceeded traps. The default is true. |
Advanced field descriptions
Use the data in the following table to use the Advanced tab.
Name |
Description |
---|---|
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. |
Name |
Specifies the name of the VLAN. |
IfIndex |
Specifies the logical interface index assigned to the VLAN. |
Type |
Specifies the type of VLAN:
|
Isid |
Specifies the I-SID number assigned to a customer VLAN (C-VLAN). The range is 0 – 16777215. The default value is 0, which indicates that no I-SID is assigned. |
Isid Name Note:
This field does not apply to all hardware platforms. |
Specifies the name of the I-SID. |
ProtocolId |
Specifies the network protocol for protocol-based VLANs. If the VLAN type is not protocol-based, None is displayed in the Basic tab ProtocolId field. |
AgingTime |
Specifies the timeout period for dynamic VLAN membership. A potential VLAN port is made ACTIVE after it receives a packet that matches the VLAN; if no such packet is received for AgingTime seconds, the port is no longer active. The default is 600. |
MacAddress |
Specifies the MAC address assigned to the virtual router interface for this VLAN. This field is relevant only after the VLAN is configured for routing. This MAC address is used as the Source MAC in routed frames and ARP replies. |
Vlan Operation Action |
Performs an operation on the VLAN. The values are:
The default is none. |
Result |
Specifies the result code after you perform an action. |
NlbMode |
Enables or disables Microsoft Network Load Balancing (NLB) operations on the VLAN. The default is disabled. |
SpbMulticast |
Enables or disables Multicast over Fabric Connect. The default is disabled. |
SpbPimGatewayMulticast |
Enables or disables SPB-PIM Gateway Multicast on a VLAN. The default is disabled. |
RmonEnable |
Enables or disables Remote Monitoring (RMON) on the interface. The default is disabled. |
Ipv6FhsSnoopDhcpEnable |
Enables or disables IPv6 dhcp snooping on a VLAN. The default is disabled. |
Ipv6FhsNDInspectionEnable |
Enables or disables neighbor discovery (ND) inspection on a VLAN. The default is disabled. |
DvrEnable |
Enables or disables DvR on a VLAN that is configured on the DvR Controller. The default is disabled. Note:
You must enable DvR on every VLAN that is configured on a DvR Controller. |
DvrGwIpv4Addr |
Specifies the DvR gateway IPv4 address for a VLAN. Important:
Ensure that you configure the same gateway IPv4 address on all Controllers in the DvR domain that belong to a VLAN. |
DvrGwIpv4OneIp |
Enables or disables the DvR One IP for a VLAN. The default is disabled (false). |
Circuitless IP field descriptions
Use the data in the following table to use the Circuitless IP tab.
Name |
Description |
---|---|
Interface |
Specifies the number assigned to the interface, from 1 to 256. |
Ip Address |
Specifies the IP address of the CLIP. |
Net Mask |
Specifies the network mask. |
Basic Field Descriptions
Use the data in the following table to use the Basic tab.
Name |
Description |
---|---|
Id |
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. |
Name |
Specifies the name of the VLAN. |
IfIndex |
Specifies the logical interface index assigned to the VLAN. |
Color Identifier |
Specifies a proprietary color scheme to associate a color with the VLAN. Color does not affect how frames are forwarded. |
Type |
Specifies the type of VLAN:
|
MstpInstance |
Identifies the MSTP instance. |
VrfId |
Indicates the Virtual Router to which the VLAN belongs. |
VrfName |
Indicates the name of the Virtual Router to which the VLAN belongs. |
PortMembers |
Specifies the slot/port of each VLAN member. The sub-port only appears for channelized ports. |
ActiveMembers |
Specifies the slot/port of each VLAN member. The sub-port only appears for channelized ports. |
StaticMembers |
Specifies the slot/port of each static member of a policy-based VLAN. The sub-port only appears for channelized ports. |
NotAllowToJoin |
Specifies the slot/ports that are never allowed to become a member of the policy-based VLAN. The sub-port only appears for channelized ports. |
ProtocolId |
Specifies the network protocol for protocol-based VLANs. This value is taken from the Assigned Numbers of remote function call (RFC). If the VLAN type is port-based, none is displayed in the Basic tab ProtocolId field. |
AgingTime |
Specifies the timeout period, in seconds, to age out dynamic members of this VLAN. This field only applies to policy-based VLANs. The default is 600. |
Note
If you or another user changes the name of an existing VLAN using the VLAN Basic tab (or using CLI), the new name does not initially appear in EDM. To display the updated name, perform one of the following actions:
-
Refresh your browser to reload EDM.
-
Log out of EDM and log in again to restart EDM.
-
Click Refresh in the VLAN Basic tab toolbar. If the old VLAN name appears in other tabs, click Refresh on those tabs as well.
