The debugging ospf packet dd command output, however, shows that the MTU contained in the packet received by RouterB is 0. This indicates that the link is not working properly. Run the following command on RouterA to ping RouterB. It is found that packet loss occurs. <RouterA> ping ...
The PEs deliver the OSPF default route to guide service interworking between the two cities. PE1 and PE2 each have another interface connected to the same UMG device. The IP addresses of the two interfaces are 10.1.1.33, and the two interfaces are bound to the VPN instance. In normal ...

A.Yes, however HSRP and OSPF are two different protocols that achieve different things. The OSPF that runs on the router advertises the two physical interfaces and not the virtual IP address. When this router becomes active, it broadcasts a gratuitous ARP packet with the HSRP virtual MAC addr...

Router(config)# ipv6 unicast-routing By default, IPv6 traffic forwarding is disabled, so using this command enables it. Also, as you’ve probably guessed, IPv6 isn’t enabled by default on any interfaces either, so we have to go to each interface individually and enable it. There are a...
Additionally, the IPv4 address assigned to the loopback interface can be significant to processes on the router that use an interface IPv4 address for identification purposes, such as the Open Shortest Path First (OSPF) routing process. By enabling a loopback interface, the router will use the ...
