What is Multi-homing ?
Multi-homing means having multiple connections to the Internet.
What is HSRP?
Hot Standby Router Protocol (HSRP) allows routers use a shared IP or Virtual IP that act as a single virtual router, maintaining connectivity even if the first hop router fails, because other router is on hot standby
Why do I need BGP and HSRP configured on the same routers?
VRF-lite is a feature that enables a service provider to support two or more VPNs, where IP addresses can be overlapped among the VPNs. VRF-lite uses input interfaces to distinguish routes for different
VPNs and forms virtual packet-forwarding tables by associating one or more Layer 3 interfaces with each VRF. Interfaces in a VRF can be either physical, such as Ethernet ports, or logical, such as VLAN
SVIs, but a Layer 3 interface cannot belong to more than one VRF at any time.
VRF-lite allows the network administrator to create multiple routing instances on the same routing device within the enterprise. VRF-lite can be useful when you need to isolate traffic between two networks sharing the same routing platform or if you have multiple networks with overlapping addresses sharing the same physical network. Multiple instances of routing protocols can be used for different VRFs on the same device to exchange routes dynamically with a direct connected device.
NAC Profiler is one of the most interesting products for network administrators.
Cisco® NAC Profiler enables network administrators to keep a real-time, contextual inventory of all devices in a network. It greatly facilitates the deployment and management of Cisco network admission control (NAC) systems by discovering and tracking the location and type of all LAN-attached endpoints, including those that are not capable of authenticating. It also uses the information about the device to determine the correct policies for NAC to apply.
