VLAG Configuration - VLANs Mapped to MSTI

Configure the ISL
1. Configure STP:
2. Configure the ISL ports and place them into a portchannel (dynamic or static):
3. Configure VLAG Tier ID. This is used to identify the VLAG switch in a multi‐tier
environment.
4. Configure the ISL for the VLAG peer.

Follow the steps in this section to configure VLAG in environments where the STP
mode is MSTP and no previous VLAG was configured.
The ISL connecting the VLAG peers is shared by all their VLAGs. The ISL needs to
be configured only once on each VLAG peer. Ensure you have the same region
name, revision and VLAN‐to‐STG mapping on both VLAG switches.
CN4093(config)# spanning­tree mode mst
CN4093(config)# interface port 1­2
CN4093(config­if)# switchport mode trunk
CN4093(config­if)# lacp mode active
CN4093(config­if)# lacp key 200
CN4093(config­if)# exit
CN4093(config)# vlag isl adminkey 200
Note:
a. In this case, a dynamic trunk group is shown. A static trunk (portchannel)
could be configured instead.
b. ISL ports and VLAG ports must be members of the same VLANs.
CN4093(config)# vlag tier­id 10
Make sure you configure the VLAG peer (VLAG Peer 2) using the same ISL trunk
type (dynamic or static), the same VLAN for vLAG ports and vLAG ISL ports, and
the same STP mode and tier ID used on VLAG Peer 1.
