Router bgp 345 Store the result of the CRC cyclic redundancy check S uppercase S , stale , indicating expired routes When a router connects through a multi-access medium such as Ethernet, a dynamic mechanism is needed to discover each other, such as ARP . ARP can map Layer 2 addresses to IP . If it is a frame relay multipoint link, the adjacency relationship can be learned by using an address resolution protocol,ccnp tshoot 2018, a mapping table, and the like. There are two types of Layer 3 interfaces, one is SVI above we have already discussed, the other is routed port , or no switchport . Note that the SVI port is a virtual interface and the routed port is a physical interface. The Layer 3 switch supports the physical interface as a Layer 3 interface similar to the physical interface of the router. The specific configuration is to enter the configuration mode of a specific interface. After the no switchport command is used, the interface becomes an L3 routing interface. You can Configuring IP for him is like operating an Ethernet port on a router to operate it.
