Configuring Load-Balancing Groups

You configure Martini circuits with load-balancing groups in a separate mode, in which the member layer 2 subinterfaces are entered one by one. For example, the following commands configure two Martini circuits to different PE routers, in the same load-balancing group 100, sharing the candidate Ethernet ports 2/0 and 3/0:

host1(config)#mpls l2transport load-balancing-group 100 mpls-relay 2.2.2.2 202 host1(config-mpls-l2-group)#member interface fast 2/0.500

You can also configure member interfaces as described in the following sections:

Adding a Member Interface to a Group Circuit

You specify the lower interface as a member interface, as in the following example.

host1(config)#mpls l2transport load-balancing-group 100 mpls-relay 2.2.2.2 202 host1(config-mpls-l2-group)#member interface fast 2/0.500

Removing Member Subinterfaces from a Circuit

To remove a member subinterface from a circuit, either issue the no member interface command (from the L2 Transport Load-Balancing-Group Configuration mode) or issue the no mpls-relay command at the VLAN or S-VLAN subinterface level. Each of the following examples removes member Fast Ethernet subinterface 13/0.2 from the load-balanced Martini circuit:

host1(config)#mpls l2transport load-balancing-group 100 mpls-relay 2.2.2.2 202 host1(config-mpls-l2-group)#no member interface fast 13/0.2

host1()#interface fast 13/0.2 host1(config-subif)#no mpls-relay
