PBB EVPN on Dual Homed Device/Multi Homed Device with Active/Active
per Flow load-balancing
This examples covers:
• PBB-EVPN service among three PEs in the same AS with a dual homed CE (behind PE1 and PE2) and
a single homed CE (behind PE3)
• PE1/PE2 configured to perform active/active per Flow loadbalancing allowing ingress traffic from the
same I-SID to be handled by both PEs
• Example shows EVI carrying traffic from a single I-SID
• PBB I-SID values must match among PEs connected to a common dual homed site
• ICCP must be configured in PE1, PE2 using a new mode (mode singleton); where no ICCP neighbor is
configured. Note that MLACP parameters such as system MAC/priority must be identical while MLACP
node ID must be unique on PE1/PE2
• ESI must be identical on PEs connected to a common dual homed site. Example shows default behavior
where ESI value is auto-derived from CE's LACP information
• PBB source MAC must be the same on PEs connected to a dual homed site operating on active/active
per flow load-balancing. Example shows default behavior where PBB source MAC value is auto-derived
from CE's LACP information
• CE must be configured with one bundle interface that includes all member interfaces connecting to both
PEs
• BGP RD/RT auto-derived from BGP ASN and EVI ID
