2.  Router communicates two different network with each other  A Cisco router does not contain disk storage mechanisms such as hard disks. Therefore, the router requires certain hardware and firmware components for proper functioning.

8. There are 5 interface of Router 1. Serial 2. Ethernet 3. BRI 4. Auxillary mode 5. Consol mode

9. 1. User mode 2. Privilege mode 3. Configuration mode 4. Interface mode

10. 1:- Distance Vector Routing Protocol i:- R.I.P. ii:-I.G.R.P. 2:- Link State Routing Protocol i:-O.S.P.F. 3:- Hybrid Vector Routing Protocol i:- E.I.G.R.P.

12.  Access Control List is two type 1. Standard 2. Extended

13. For Host to Network Blocking Router(config)#access-list 1 deany 10.0.0.0 Router(config)#access-list 1 permit any Router(config)#ip access-group 1 in
