The thinking behind that is that if there is any way to your router you can get to the loop-back - if you used a real interface address if that was the interface that was down, you would lose access. The main reason for using a loop-back on a switch as the management address...
To enable LFA, use the fast-reroute command, then the area we want to protect, area 0 in our case, next we have to configure the priority, there are two options; high and low. When we use the high priority, OSPF treats loopback and /32 prefixes with higher priority. When we c...

The modus operandi of SVIs is simple. You start by creating the Layer 2 VLAN on the switch, and then assign an IP address on the VLAN Layer3 interface (SVI), just as you would on a physical router interface. The major difference here is that the SVI Layer 3 interface isvirtual. This...

An EBGP peer relationship is established between a Cisco device and a Huawei device using loopback interface addresses. After the link is disconnected unexpectedly, flapping occurs on the EBGP peer that should be in the Down state. Therefore, Cisco uses the neighbor ip-address ttl-security hops ...
