I am wondering if some can explain me below scenario please
you have two routers in different DCs and they only have layer 2 connectivity, hence no the IP addresses assigned to their outside interface, they both have 1 loopback on each router and I want to form an adjacency between their loopbacks.
Can anyone explain, how to achieve this, or redirect me to the relevant cisco documentation please.
We are talking about running a layer3 routing protocol between two DC. Do you have layer3 connectivity between them? Are you able to ping eachother loopback ips. I guess not. If they have layer2 connectivity, then physical port would be either access port or trunk port. In any case we can pass one vlan and configure a SVI interface (interface vlan <vlan-number>) for that vlan. Assign /30 ip address and over this you can have OSPF adjacency.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
