Inter-VDC connection

[olly ahmed]

I configured 3 VDCs(A,B & C) and now wants to connect them. Here A is the defualt or admin VDC. Now I want to connect vdc B & C. Cable connection setup is done. If I wants vdc B & C to communicate, do I need to add any configuration in default VDC (A) for this or only configuration is needed in two VDCs respectively. Would appreciate if anyone can share a sample step by step configuration too so that it becomes more clear to understand and visualize.

Hi;

VDC is exactly like you have multiple separate switches. And for interconnectivity of switches you can connect & configure either L2 or L3 links as per design.

To configure the VDC you need to first create VDC and allocate the interface.

N7K-VDCA (config)# vdc N7K-VDCA

N7K-VDCA (config-vdc)# allocate interface e1/1-8, e2/1-8

N7K-VDCA (config)# vdc N7K-VDCB

N7K-VDCA (config-vdc)# allocate interface e1/9-16, e2/9-16

Physical connect the VDCA & VDCB (i.e L2 Trunk)

N7K-VDCA(config)# interface E1/1

N7K-VDCA(config-if)# description ** Connected to VDCB ***

N7K-VDCA(config-if)# switchport

N7K-VDCA(config-if)# switchport mode trunk

N7K-VDCA(config-if)# switchport trunk allowed vlan 1-10

N7K-VDCA(config-if)# no shut

N7K-VDCA(config)#switchto vdc N7K-VDCB

N7K-VDCB(config-if)#interface E1/8

N7K-VDCB(config-if)# description ** Connected to VDCA ***

N7K-VDCB(config-if)# switchport

N7K-VDCB(config-if)# switchport mode trunk

N7K-VDCB(config-if)# switchport trunk allowed vlan 1-10

N7K-VDCB(config-if)# no shut
