Basics of VXLAN
Maximum number of VLAN is 4000 where VXLAN can give 16 million Virtualization by adding 24 bit VNI network Identifier. This Vxlan encapsualtion is called Virtual Ethernet modul or VEM. Each VEM has IP address. The IP is assigned to interface VTEP==>> Vxlan Tunnel end point Each VTEP interfaces associated with one or more VNIs. VXLAN usage is can create multiple tunnels over a underlay network. Mainly used on Spine- Leaf Design bum traffic for broadcast VXLAN can do the load balance between the port channel. Multiple VNI can associated with same multicast group. ========================================= HSRP VS VRRP VS GLBP HSRP and GLBP is cisco properatory VRRP is opensource protocol. HSRP active and standby and VRRP follows master and slave. VRRP can use interface IP as virtual IP. HSRP sents Hello messages but VRRP sents adverticements. GLBP is used to do for load balancing between routers. It uses different mac address for different machine traffic. SSO: ====...
