cisco数据中心理论小记-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

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
