VDX NOS: Can fabric virtual gateways be assigned to a VRF?

[wgs]

We currently use our VDX for only layer 2 functions. We are looking at turning on layer 3 routing, and the fabric route virtual gateway functionality.

I see the VDX supports 32 vrfs, and the vrf documentation describes assigning ip interfaces and vrrp/vrrp-e addresses to vrf domains. I do not see anything in the documentation that explains if an ip fabric-virtual-gateway address can be added to vrf.

Example from docs:
(config)# interface ve 6000 device
(config-Ve-6000)# attach rbridge-id 10,11,12
(config-Ve-6000)# no shutdown
(config-Ve-6000)# ip fabric-virtual-gateway
(config-ip-fabric-virtual-gateway )# gateway-address 10.65.40.100/24
(config-ip-fabric-virtual-gateway )# exit
FROM VRF DOCS--->>(config-Ve-6000)# vrf forwarding orange

will this work?

Unfortunately I do not have a lab to test this on.

Thank you

Thank you for the quick answer. I'm glad this works and I do not have to use vrrp instead..

wgs,

Yes, this is possible, here is the correct process:

Step 1:

Configure the VRF on each RB attached:

code:

Static-Lab-SM08_VDX1(config)# rbr 1   
Static-Lab-SM08_VDX1(config-rbridge-id-1)# vrf orange
Static-Lab-SM08_VDX1(config-vrf-orange)# address-family ipv4 uni
Static-Lab-SM08_VDX1(vrf-orange-ipv4-unicast)#

Static-Lab-SM08_VDX1(config)# rbr 2   
Static-Lab-SM08_VDX1(config-rbridge-id-2)# vrf orange
Static-Lab-SM08_VDX1(config-vrf-orange)# address-family ipv4 uni
Static-Lab-SM08_VDX1(vrf-orange-ipv4-unicast)# exit

Step 2:

Setup Fabric Virtual Gateway globally

code:

Static-Lab-SM08_VDX1(config)# router fabric-virtual-gateway 
Static-Lab-SM08_VDX1(conf-router-fabric-virtual-gateway)# address-family ipv4
Static-Lab-SM08_VDX1(conf-address-family-ipv4)# exit
Static-Lab-SM08_VDX1(conf-router-fabric-virtual-gateway)# exit

Static-Lab-SM08_VDX1(config)# interface ve 6000
Static-Lab-SM08_VDX1(config-Ve-6000)# attach rbridge-id add 1,2
Static-Lab-SM08_VDX1(config-Ve-6000)# no shut
Static-Lab-SM08_VDX1(config-Ve-6000)# ip fabric-virtual-gateway 
Static-Lab-SM08_VDX1(config-ip-fabric-virtual-gw)# gateway-address 10.65.40.100/24
Static-Lab-SM08_VDX1(config-ip-fabric-virtual-gw)# exit

Step 3:

Configure each RB with the appropriate VE

code:

Static-Lab-SM08_VDX1(config)# rb 1
Static-Lab-SM08_VDX1(config-rbridge-id-1)# int ve 6000
Static-Lab-SM08_VDX1(config-rbridge-Ve-6000)# vrf forwarding orange
Static-Lab-SM08_VDX1(config-rbridge-Ve-6000)# ip fabric-virtual-gateway 
Static-Lab-SM08_VDX1(config-ip-fabric-virtual-gw)# enable
Static-Lab-SM08_VDX1(config-ip-fabric-virtual-gw)# exit

Static-Lab-SM08_VDX1(config)# rb 2
Static-Lab-SM08_VDX1(config-rbridge-id-2)# int ve 6000
Static-Lab-SM08_VDX1(config-rbridge-Ve-6000)# vrf forwarding orange
Static-Lab-SM08_VDX1(config-rbridge-Ve-6000)# ip fabric-virtual-gateway 
Static-Lab-SM08_VDX1(config-ip-fabric-virtual-gw)# enable
Static-Lab-SM08_VDX1(config-ip-fabric-virtual-gw)# exit

I hope this answers your question
