Solution Overview (4) Establishment of inter-AFBR softwires is decoupled from the distribution of AF reachability information advertise softwire tunnel encapsulation and preferences once and then many AF prefixes and which softwire tunnel to use. more efficient BGP packing and processing by eliminating advertisement of duplicate softwire tunnel info for each prefix enables policy control on AFBR for softwire installation and selection Not mandated to store AF prefixes in VRFs on AFBR only needed to support overlapping address requirement or if operator prefers this configuration |
