(45 cards)
FHRP
First Hop Redundancy Protocol
HSRP
Hot Standby Router Protocol, which is a Cisco proprietary protocol “active” only one standby
VRRP
Vitual Router Redundancy Protocol. Open standard. “Master” can have more than one standby
GLBP
Gateway Load Balancing Protocol. CIsco Prop and up to 4 AVF
GLBP-AVF
Gateway Load Balancing Protocol-Active Virtual Forwarder; a router responsible for forwarding traffic associated with a specific virtual MAC addres
GLBP-AVG
Active Virtual Gateway
RPR
Route Processor Redundnacy, >2 min failover, traffic disrupted.
RPR+
Route Processor Redundnacy more stuff boots on secondary supervisor card(plus) >30 sec failorcer, traffic distrupted.
SSO
Staeful SwitchOver, >1sec failover L2 maintained L3 disrupted
SSO with NSF
Staeful SwitchOver with non-stop forwarding, milisecond failoverno disruption
SD-Access
Software Defined Access: focuses on simplifying and automating network operations for enterprise networks. It uses Cisco’s DNA Center to provide policy-based automation, segmentation, and assurance
DNA
Digital Network Architecture; provides a single pane of glass for network management, monitoring, and troubleshooting. It uses real-time analytics and telemetry to identify issues and optimize network performance
SDN
Softwre Defined Networking; a network architecture that centralizes network control, automates management, and enables programmability through software-based policies.
T/F DNA licensing is needed for Netflow
True
DNAC
Cisco Digital Network Architecture Center. It is a centralized management and automation platform for Cisco networks that allows for simplified deployment, policy enforcement, and network operations. DNAC provides end-to-end visibility, automation, and assurance across wired, wireless, and wide-area networks.
WHat are the four layes of DNA architecture?
Management, Controller, Network, Physical
DNAC Management Layer: Four primary DNAC workflows
Cisco DNA Design
Cisco DNA Policy
Cisco DNA Provision
Cisco DNA Assurance
DNAC Management Layer
used by administrators to manage the network
What are the two subsystems for the DNAC Controller Layer?
Cisco Network Control Platform (NCP)
Cisco Network Data Platform (NDP)
Cisco Network Control Platform (NCP)
focuses on automating and controlling the network
Cisco Network Data Platform (NDP)
specializes in collecting and analyzing data to provide visibility and optimization insights
Cisco Identity Services Engine (ISE)
a policy-based access control platform that secures networks by ensuring users and devices are authenticated, authorized, and compliant before accessing resources
VXLAN (important, Brian)
(OVERLAY) VIrtual Extensible LAN , enables scalable creation of virtual Layer 2 networks over an existing Layer 3 infrastructure. The new Cisco OTV technology. 24 bit 2^^24 =16,777,216
VRF (Important Brian)
(OVERLAY) Virtual Routing and Forwarding; allows multiple instances of a routing table to coexist on the same physical router or Layer 3 switch
