Use the load-balancing flow label code command to toggle between the sub-TLV identifiers—0x11 and
0x17. If there is a mismatch between two endpoints in the load-balancing flow label code, then the PWs will
have a mismatched TLV value resulting in a load balancing failure.
The no form of the load-balancing flow label code command uses the flow label sub-TLV identifier 0x11.
In the L2VPN bridge group bridge-domain vfi autodiscovery bgp signaling-protocol submode, the static
keyword is optional. If the static keyword is not used, flow load balancing is dynamic. In this case, the routers
dynamically select ingress or egress or both traffic flows for load balancing, based on this command
configuration on both endpoints of a pseudowire. Even if this command configuration on the pseudowire’s
endpoints mismatch, the least possible of the traffic flows is enabled for load balancing. For example, consider
the following mismatched but dynamic flow load balancing configuration: if one endpoint is configured for
egress traffic load balancing, while the other is configured for ingress as well as egress load balancing, then
load balancing is enabled for egress on the first endpoint and only the ingress on the latter endpoint.
