Common commands vro commands

1. vro password settings:

Router> enable enter privileged mode router # config terminal enter global configuration mode router (config) # hostname
 
  
Set the vswitch host name router (config) # enable secret xxx set the privileged encryption password router (config) # enable password xxb set the privileged non-password router (config) # line console 0 enter the console port router (config-line) # line vty 0 4 enter the virtual terminal router (config-line) # login requires a password to verify the router (config-line) # password xx set the logon password xxrouter (config) # (Ctrl + z) return to the privileged mode router # exit return to the command
 

2. vro Configuration:

Router (config) # int s0/0 enter the Serail interface router (config-if) # no shutdown to activate the current interface router (config-if) # clock rate 64000 set synchronization clock router (config-if) # ip address
  
  
   
Set ip address router (config-if) # ip address
    
    
     
Second sets the second IProuter (config-if) # int f0/0.1 to enter the sub-interface router (config-subif.1) # ip address
      
      
        Set the sub-interface IProuter (config-subif.1) # encapsulation dot1q
       
         Bind vlan relay protocol router (config) # config-register 0x2142 skip the configuration file router (config) # config-register 0x2102 normal use of the configuration file router # reload reboot
       
      
     
    
   
  
 

3. vro file operations:

Router # copy running-config startup-config save configuration router # copy running-config tftp save configuration to tftprouter # copy startup-config tftp boot configuration saved to tftprouter # copy tftp flash: upload the file to flashrouter # copy tftp startup-config to download the ROM status of the configuration file: ctrl + Break go to ROM monitoring status rommon> confreg 0x2142 skip configuration file rommon> confreg 0x2102 restore configuration file rommon> reset reboot rommon> copy xmodem:
 
  
Flash:
  
   
Transmit the file rommon> IP_ADDRESS = 10.65.1.2 from the console and set the router IPrommon> mask = route 255.0.0 to set the router mask rommon> TFTP_SERVER = 10.65.1.1 to specify the TFTP server IPrommon> TFTP_FILE = Specify the downloaded download rommon> dir flash from tftp: view the Flash content rommon> boot IOS
  
 

4. Static Routing:

Ip route
  
   
   
    
Command Format: router (config) # ip route 2.0.0.0 route 0.0.0 1.1.1.2 static route example router (config) # ip route 0.0.0.0 0.0.0 1.1.1.2 default route example
   
  
 

5. Dynamic Routing:

Router (config) # ip routing start route forwarding router (config) # router rip start the RIP route protocol. Router (config-router) # network
 
  
Set publish route router (config-router) # negihbor
  
   
Point-to-Point frame relay.
  
 

6. Frame Relay command:

Router (config) # frame-relay switching enabling frame relay switching router (config-s0) # encapsulation frame-relay enabling frame relay router (config-s0) # fram-relay lm-type cisco settings management type router (config-s0) # frame-relay intf-type DCE set to DCErouter (config-s0) # frame-relay dlci 16 router (config-s0) # frame-relay local-dlci 20 set virtual circuit number router (config-s0) # frame-relay interface-dlci 16 router (config) # log-adjacency-changes record adjacent changes router (config) # int s0/0.1 point-to-point setting sub-interface point-to-point router # show frame pvc display permanent virtual circuit router # show frame map display ing

7. Basic Access Control List:

router(config)#access-list 
 
   permit|deny 
   
   
    router(config)#interface 
    
                  ；default:deny anyrouter(config-if)#ip access-group 
     
       in|out   ；defaultut
     
    
   
  
 

Example 1: router (config) # access-list 1 deny host 10.65.1.1router (config) # access-list 1 permit anyrouter (config) # int f0/0 router (config-if) # ip access-group 4 in Example 2: router (config) # access-list 4 permit 10.8.1.1router (config) # access-list 4 deny 10.8.1.0 0.0.255router (config) # access-list 4 permit 10.8.0.0 0.0.255.255router (config) # access-list 4 deny 10.0.0.0 0.20.255.255router (config) # access-list 4 permit anyrouter (config) # int f0/1 router (config-if) # ip access-group 4 in extended access control list: access-list

The overload parameter is used by PAT to map an internal IP address to a port with a different public IP address.

8. The router sub-interface is encapsulated as 8021Q (Supplement)

Encapsulation dot1q 2 is set to 802.1Q as the Encapsulation type, and 2 is the ID of the sub-interface number. Here is an example. You can set it as needed.
