I have enabled only SSH publickey authentication on the router, and disabled password and keyboard authentication. But Ansible is still able to authenticate on the router using a password.IOS: 15.5Linux: Ubuntu Server 22.04From a Linux VM I am not ab...
I have the following topology:IOU3 is the ABR, and is summarizing Area 0 prefixes as a summary route 2000::/16 into Area 1.IOS version: 15.5.RFC1583 is ENABLED on IOU3 (and everywhere else), which means that the cost of the summary route should be ba...
I created a little topology in GNS3 with 3 routers. And the routing tables on R1 and R3 should have two routes to a subnet:R1 should have two equal cost routes to subnet 10.1.5.0/24R3 should have two equal cost routes to subnet 10.1.4.0/24R1 routing ...
I configured NAT and DHCP relay in GNS3, and all hosts have end-to-end reachability, I can ping PC44 from PC11 and PC22, and also from PC33 if I configure a static IP address.On the NAT router (R11), I also configured DHCP relay with 'helper-address'...
Is there a debug command available on a switch that lets me see the frames being forwarded and dropped?I am testing some scenarios and I want to be notified when a switch receives a frame on a trunk link from a VLAN that is not configured on that swi...
Oh ok that's interesting that password authentication still works if the SSH client insists on using a password... I thought that password authentication should not be possible at all, because on the router only publickey is allowed:ip ssh server alg...
Yes I understand now. The "O" in R1 routing table next to 10.1.5.0/24 means INTRA-area route, I explain it to myself as: the subnet is part of an area of which the local router (R1) is part of.In this case 10.1.5.0/24 is part of Area 1, and next-hop ...
That is probably the correct solution, so I will mark it as Accepted.But my router IOS doesn't support either the ip dhcp relay source-interface interface command nor the global command. These are all the commands available in interface mode:R11(conf...
