Configuring MPLS VLLs

Specifying a LAG group as the endpoint of a VLL
The endpoint of a VLL can be a LAG group. When the endpoint of a VLL is a LAG group, the VLL
traffic load is distributed to the customer edge (CE) device across all of the LAG group’s ports, using
a hashing mechanism.
Figure 59 illustrates a sample configuration where a LAG group of two ports serves as the endpoint
of a VLL.
FIGURE 59 Specifying a LAG group as the endpoint of a VLL
To configure a LAG group like the one in Figure 59 , enter commands such as the following.
Brocade(config)# lag red dynamic
Brocade(config-lag-red)# ports ethernet 1/1 to 1/2
Brocade(config-lag-red)# primary port 1/1
Brocade(config-lag-red)# ports ethernet 1/2
Brocade(config-lag-red)# deploy
To configure a VLL like the one in Figure 59 , enter commands such as the following.
Brocade(config)# router mpls
Brocade(config-mpls)# vll test2 40000
Brocade(config-mpls-vll)# vll-peer 10.10.10.10
Brocade(config-mpls-vll)# untagged e 1/1
NOTES: When the user first creates a LAG and then configure a VLL instance, the port the user
specifies as the VLL endpoint must also be the port the user specified as the primary port of the LAG
group:
• When the user later deletes the LAG from the configuration, only the primary port is
still a port of the VLL and all secondary ports become normal ports.
• When the user specified a tagged endpoint for the VLL instance, all of the ports in the
LAG must be tagged.
• Traffic received from any port in the LAG is forwarded to the VLL instance. All traffic is
matched to its VLAN.
• Both static and dynamic LAGs are supported.
Enabling VLL MTU enforcement (optional)
The user can selectively enable local and remote VLL MTU mismatch checking using the following
command.
Brocade(config)# router mpls
Brocade(config-mpls)# vll-mtu-enforcement
Syntax: [no] vll-mtu-enforcement
