CCNA2: Routing concepts (Network Chracteristics (Topology (Physical…

- - - - Arrangement of physical devices
    - - describes how the network devices appear connected to network users.
- - - - Running IOS
      - Running configuration files
      - IP routing and ARP tables
      - Packet buffer
      - volatile memory - temporary storage
    - - bootup instructions
      - basic diagnostic software
      - limited IOS in case router cannot load the full featured IOS
      - non-volatile memory - permenant storage
    - - non-volatile memory
      - IOS
      - Other system related files
- - - - rarely implemented
  - - - Flow information for subsequent packages is stored in fast forward cache #
  - - - The FIB maintains next-hop address information based on the information in the IP routing table.The other part of the process is the adjacency table, the adjacency table maintains L2 next hop addresses for all FIB entries.
- - - - Cable modem = Connects to Internet service provider (ISP)
  - - - Edge router sites at the edge or boundary of a network
    - - WAN service provider (SP)
      - ISP = backup purposes
- - - - Identifes router a packet is sent to when the destination is not on the same local network subnet
      - address of the interface on the router connected to the local network
- - - - show interface
      - show ipv6 routers
- - - - Directly connected routes
      - Remote routes
      - Network or next hop associations
  - - - Added when interface configured
      - Marked with L
    - - Added to routing table when an interface is configured and active
    - - Adde when a route is manually configured and the exit interface s active
    - - Added with protocols like EIGRP or OSPF are implemented
