Interface Configuration
Interaction with Layer 4 Load-Balancing Feature
The 7x50 supports the inclusion of the L4 header in the hash routing for a VLL/VPLS SAP and for
an IES/VPRN interface. The user enables this at the system level using the following command:
configure>system>l4-load-balancing
When this option is enabled, and the LSR hashing is set to lbl-ip or ip-only, the 7x50 LSR hash
routine will also include the Layer 4 header in addition to the IP header in the LSR hash routine.
The user can include or exclude Layer 4 header on a specific network interface by applying the
following command:
config>router>interface>lsr-load-balancing [include-ip [l4-hdr] | exclude-ip]
