Due to the differences between the fixed network and mobile network in terms of access bandwidth, terminal authentication, and terminal mobility, how to view and solve these differences has become a key issue for IMS-based FMC.
The concept and architecture of IMS was initially proposed by 3GPP In R5. As a new domain in the third generation mobile communication, IMS provides multimedia services for users and achieves separation of business and control.

Network Topology
As mentioned above, OSPF is a link status protocol. How does OSPF describe the link connection status?
Abstract Model 1 indicates that an Ethernet interface of a router is connected to only one Ethernet segment instead of other routers. In this case, router R1 running OSPF can only identify itself and cannot identify the devices (hosts, etc.) on this network segment ); abstract Model 2 indicates that router R1 is connected to a router R2 through a point-to-point link (such as P
Lab requirements:Set up the topology, import the pre-configuration, and troubleshoot the following errors.1. The link between R1 and SW1 cannot start;2. SW1 cannot start the trunk link between SW2 and SW3;3. Problems with etherchannel between SW2 and SW3;4. The HSRP between SW2 and SW3 cannot be automatically switched;5. R1 and R2 cannot dynamically obtain the address from DHCP server R3;6. R1 cannot access the server 5.5.5.5 on the ISP R5 without R2;
