A network administrator has configured OSPFv2 on the two Cisco routers as shown. declaring a neighbor to be inaccessible.Which step in the link-state routing process is described by a router building a link-state database based on received LSAs?.The database description (DBD) packet contains an abbreviated list of the LSDB sent by a neighboring router and is used by receiving routers to check against the local LSDB. Which type of OSPFv2 packet contains an abbreviated list of the LSDB of a sending router and is used by receiving routers to check against the local LSDB?.When a network topology change is detected (incremental updates) Updates (LSUs) are sent to neighbors only under the following conditions:
#Ospfv2 with router on a stick full
When an OSPF network is converged and no network topology change has been detected by a router, how often will LSU packets be sent to neighboring routers?Īfter all LSRs have been satisfied for a given router, the adjacent routers are considered synchronized and in a full state.The active and passive states are used by EIGRP. 802.CCNA3 v7 – Practice Final – ENSA Answers 001 Answers Explanation & Hints:.EAPoL (Extensible Authentication Protocol over LAN).Authentication, Authorization, Accounting.GRE Tunnel Configuration with Cisco Packet Tracer.Local SPAN Configuration on Packet Tracer.Remote SPAN Configuration on Packet Tracer.VRRP (Virtual Router Redundancy Protocol).VLAN Configuration on Cisco Packet Tracer.VLAN Port Assignment and VLAN Port Types.Inter VLAN Routing with Router on Stick Topology.Inter VLAN Routing Configuration Example.Inter VLAN Routing Configuration on GNS3.STP Configuration on Cisco Packet Tracer.RSTP Configuration on Cisco Packet Tracer.STP Portfast Configuration on Cisco Packet Tracer.PVST+ and Rapid PVST+Configuration on Packet Tracer.Basic Cisco Router Security Configuration.Standard ACL Configuration With Packet Tracer.Access Control Lists for Traffic Control.Dynamic NAT Configuration with Packet Tracer.Static NAT Configuration with Packet Tracer.Etherchannel Cisco PAgP Configuration on GNS3.Cisco DHCP Relay Agent Configuration with GNS3.Point-to-Point Protocol over Ethernet (PPPoE).Frame Relay Point-to-Point Configuration.Frame-Relay Configuration with both Inverse-ARP and Frame-Relay Map.BGP Configuration Example on Packet Tracer.Cisco BGP Route Reflector Configuration on GNS3.OSPF(Open Shortest Path First) Overview.OSPFv3 (Open Shortest Path First Version 3).OSPFv3 Configuration Example on Cisco IOS.OSPF Standard Area and Backbone Area on Cisco Packet Tracer.OSPF External Routes on Cisco Packet Tracer.OSPF Stub Area and Totally-Stub Area on Cisco Packet Tracer.OSPF NSSA and Totally NSSA on Cisco Packet Tracer.EIGRP For IPv6 Configuration On Cisco IOS.EIGRP (Enhanced Interior Gateway Routing Protocol).RIPng Configuration Example on Cisco IOS.Static Route Configuration on Cisco Routers.IPv6 Static Route Configuration on Cisco IOS.ICMP (Internet Control Message Protocol).Because for both OSPv2 and OSPv3, Router ID is in IPv4 format. Beside, we will configure a router ID in IPv4 format. Now, it is time to configure OSPFv3 process under each router. The Link-local addresses required for neighbourship, will produce Link-local addresses with this command. We will use “ ipv6 address -ipv6address- eui-64“ commands. In the third step, we will do the IPv6 address configuration/strong>. Secondly, we will enable IPv6 under interfaces with “ ipv6 enable” command. Now, let’s go to each COnfiguration steps one by one.įirstly, we will enable global IPv6 Routing on each Router with “ ipv6 unicast-routing” command. Adding Interfaces to OSPFv3 Process and Areas As you can see, there are three areas and six routers in this topology.įor OSPFv3 Configuration, we will follow the below steps one by one:Ħ. Here, we will configure OSPFv3 for the below topology. OSPFv3 is the IPv6 cabaple version of OSPF.
