PBB EVPN on Dual Homed Device/Multi Homed Device with Active/Active
per Service load-balancing and Dynamic Service Carving
This example 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 service (i.e. per-ISID) loadbalancing with dynamic
service carving/DF election allowing traffic from some I-SIDs to be handled by PE1 while the rest to be
handled by PE2
• EVI carrying traffic from two I-SIDs
• 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. ICCP configuration required to handle core isolation failures. Example uses same MLACP
system mac/priority and unique MLACP node values on PE1/PE2
• ESI must be identical between PEs for a dual homed site. User configuration must be entered to guarantee
that
• PBB source MAC must be different on each PE connected to a dual homed site. By default, PE uses
system-wide PBB source MAC
• CE must be configured with two bundle interfaces. One for each set of member interfaces leading to a
different PE
• BGP RD/RT auto-derived from BGP ASN and EVI ID
