cisco數據中心理論小記-5

=====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  （不一定會使用MPBGP-E***技術 ，使用 LISP和SDN 都可以實現VXLAN）
   MPBGP-E***
BID---冗餘 RP ---幻影RP phantom RP 分爲primary and secondary ip

=====e***v4=====
mpls ***理解
PE上做mpgbp,rd用來區分客戶的.***V4傳的是rd+prefix.RT import/export訪問權 ，可以用來區分不同客戶相同私網的作用.

MPBGP-支持rd auto,

E***-NLRI-網絡層可達信息
用來傳mac(route type2), mac+ip(route type2), external internal subnet prefixs (route type5) 只關心前綴


show bgp l2*** e*** [rd]

如果是傳 mac
bgp routing table entry for [2]-route type:[0]-ESI:[0]-Ethtag(關聯vlan):[48]-mac address length:[0000.3001.1011]-Mac adress:[0.0.0.0]/216
mac
mpls label1 l2vni
router target for mac-vrf
mac attribute 是必須的


如果是傳 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


如果傳ip prefix
ip prefix
mpls label
route target for ip-vrf
router mac
