16 Enable peer routing.
VLT DOMAIN CONFIGURATION mode
peer-routing
If you enable peer routing, a VLT node acts as the proxy gateway for its peer.
17 Repeat steps 1 through 16 for the VLT peer node in Domain 1.
18 Repeat steps 1 through 16 for the first VLT node in Domain 2.
19 Repeat steps 1 through 16 for the VLT peer node in Domain 2.
To verify the configuration of a VLT domain, use any of the show commands described in
VLT Sample Configuration
To review a sample VLT configuration setup, study these steps.
1 Configure the VLT domain with the same ID in VLT peer 1 and VLT peer 2.
VLT DOMAIN mode
vlt domain domain id
2 Configure the VLTi between VLT peer 1 and VLT peer 2.
3 You can configure LACP/static LAG between the peer units (not shown).
CONFIGURATION mode
interface port-channel port-channel id
NOTE: To benefit from the protocol negotiations, Dell Networking recommends configuring VLTs used as facing hosts/
switches with LACP. Ensure both peers use the same port channel ID.
4 Configure the peer-link port-channel in the VLT domains of each peer unit.
INTERFACE PORTCHANNEL mode
channel-member
5 Configure the backup link between the VLT peer units (shown in the following example).
6 Configure the peer 2 management ip/ interface ip for which connectivity is present in VLT peer 1.
EXEC Privilege mode
show running-config vlt
7 Configure the peer 1 management ip/ interface ip for which connectivity is present in VLT peer 1.
EXEC mode or EXEC Privilege mode
show interfaces interface
8 Configure the VLT links between VLT peer 1 and VLT peer 2 to the top of rack unit (shown in the following example).
9 Configure the static LAG/LACP between ports connected from VLT peer 1 and VLT peer 2 to the top of rack unit.
EXEC Privilege mode
show running-config entity
10 Configure the VLT peer link port channel id in VLT peer 1 and VLT peer 2.
EXEC mode or EXEC Privilege mode
show interfaces interface
11 In the top of rack unit, configure LACP in the physical ports.
EXEC Privilege mode
