What does Auto Attach (AA) solve ?
! SPB provides for a more scalable and simpler Ethernet network, AA provides an automated means for attachment for
devices not supporting IEEE 802.1ah to individual services
! AA uses IEEE 802.1AB Link Layer Discovery Protocol (LLDP) to simplify and automate attachment of endpoints to
ISID based services
! Defines a method of using IEEE 802.1AB Link Layer Discovery Protocol (LLDP) with IEEE 802.1aq Shortest Path
Bridging (SPB) network to automatically attach network devices not supporting IEEE 802.1ah to individual services in
a SPB network
! These network devices typically do not support SPBM, MAC- in-MAC (802.1ah), nor I-SID usage and therefore cannot
easily take advantage of the SPB infrastructure without manual configuration of attachment of VLANs to I-SIDs in multiple
locations

What does SPBm solve ?! Scalability : Mac address explosion
! Loop prevention & suppression
! Use all links. Does not block and waste link resources
! Use shortest path for unicast and multicast traffic
! Ease of provisioning
! Service virtualization
! Simple encapsulation

STEP 1 of demo show auto attach with dynamic config of ISID/VLAN map on the FA-OVS via ctl command
STEP 2 of demo Invoke a vmotion migration of VM1 from ESXi1 to ESXi2 and show re-attach with Fabric attach changes on ERS4850 to port 3 and traffic re-establishes automatically
