  =====VXLAN=====
  MP-BGP
  af ipv4 === bgp ipv4
  add family vrf ***v4等等
  af e***-------support NLRI : host mac, VNI, ext. community (vxlan, seq)
  VXLAN-CP(不一定会使用MPBGP-E***技术 ,使用 LISP和SDN 都可以实现VXLAN)
  MPBGP-E***
  BID---冗余 RP ---幻影RP phantom RP 分为primary and secondary ip
  =====e***v4=====
  mpls ***理解
  PE上做mpgbp,rd用来区分客户的.***V4传的是rd+prefix.RT import/export访问权 ,可以用来区分不同客户相同私网的作用.
  MPBGP-支持rd auto,
  E***-NLRI-网络层可达信息
  用来传mac(route type2), mac+ip(route type2), external internal subnet prefixs (route type5) 只关心前缀
  show bgp l2*** e***
  如果是传 mac
  bgp routing table entry for -route type:-ESI:-Ethtag(关联vlan):-mac address length:-Mac adress:/216
  mac
  mpls label1 l2vni
  router target for mac-vrf
  mac attribute 是必须的
  如果是传 mac + ip
  mac and ip
  mpls label1 l2vni
  router target for mac-vrf
  mpls label2 l3vin
  route target for ip-vrf
  router mac
  ip attribute是optional
  如果传ip prefix
  ip prefix
  mpls label
  route target for ip-vrf
  router mac
  BGP *** configuration summary
  bridge模式: vlan base 1:1:1 vid---vni--evi,vlan-aware 1:1:N
  route模式:???
  =============Lan Switching=================
  1-1 multicast
  ip pim sp
  show ip mroute ---*,g
  ip pim rp-address x.x.x.x group-list Y.Y.Y.Y bid
  =================存储网络架构及服务=========================
  FC: N/F/E show interface, Trunk switch port trunk mode on
  Nport: is used to connect to a node to a fiber channel switch
  Fport: Fabric port is that conned to peripheral device (server or storage ) operation as an N port
