Triggered RIP

Triggered RIP is designed for routers that exchange all routing information from their neighbors. If the router is changed in any way, only the changes are propagated to the neighbor. The receiving router should apply the changes immediately. Changes can be caused by events such as link flaps, next hop changes, or subnet mask changes.   Triggered RIP updates are sent only when these criteria are met: When a request for a routing update is received When new informa..

Goal of This Lab

This lab should assist you in your final preparation for the CCIE Security lab exam. Sample solutions are provided here, but you need to research other various solutions on your own. Feel free to modify the questions to suit any design scenario and discover new IOS commands by using the Cisco Universe CD-ROM. This lab is not the only tool you should use; rather, it is provided here to demonstrate the minimum level of difficulty you will encounter when attempting the CCIE Sec..

Connecting VLAN Trunks with ISL

The following set of commands allows you to connect an ISL trunk to your router: Router1#configure terminal Enter configuration commands, one per line.  End with CNTL/Z. Router1(config)#interface FastEthernet0/0 Router1(config-if)#no ip address Router1(config-if)#speed 100 Router1(config-if)#full-duplex Router1(config-if)#exit Router1(config)#interface FastEthernet0/0.1 Router1(config-subif)#encapsulation isl 1 Router1(config-subif)#ip address 172.25.1.5 255.255.255.0 R..

Configuring Frame Relay PIPQ

This section looks at the configuration tasks for enabling the Frame Relay PIPQ feature on Cisco routers. Take note that Frame Relay Traffic Shaping or FRF.12 is not required for Frame Relay PIPQ to work. Frame Relay PIPQ can work with or without these features. However, recall that when Frame Relay Traffic Shaping is enabled on a Frame Relay interface, the two-level queuing hierarchy is created on the interface. With Frame Relay Traffic Shaping and the two-level queuing stru..

Filtering Based on Noncontiguous Ports

To filter noncontiguous ports, use the following commands: Router2#configure terminal Enter configuration commands, one per line.  End with CNTL/Z.Router2(config)#ip access-list extended OREILLYRouter2(config-ext-nacl)#permit tcp any host 172.25.100.100 eq 80 23 25 110 514 21Router2(config-ext-nacl)#endRouter2#   Cisco introduced the ability to filter noncontiguous ports in IOS Version 12.3(7)T.   Historically, Ci..
