2. Summary of -02 to -03 Updates Routing Clarifications (Section 3.2) – UE’s host routes are propagated to just the EPC-E neither IPv6 core routers, nor external networks – EPC-E routers establish direct BGP peering with vEPC Propagation delays through multiple BGP speaker are NOT expected – BGP Remote-NextHop I-D is in call for IDR WG adoption Operational Clarifications (Section 4.1) – EPC-E set Sharing same UE routes that provides redundancy for stable user-plane connectivity – Access Networks Inter-region hand-over case Recommended to have connectivity for all EPC-Es IPv6 access network is ideal Routing Clarifications (Section 3.2) – UE’s host routes are propagated to just the EPC-E neither IPv6 core routers, nor external networks – EPC-E routers establish direct BGP peering with vEPC Propagation delays through multiple BGP speaker are NOT expected – BGP Remote-NextHop I-D is in call for IDR WG adoption Operational Clarifications (Section 4.1) – EPC-E set Sharing same UE routes that provides redundancy for stable user-plane connectivity – Access Networks Inter-region hand-over case Recommended to have connectivity for all EPC-Es IPv6 access network is ideal Most recent full-presentation is found at following link: http://yegin.org/NGmobility/20140327-vEPC.pdf
