CCIE Lab Quest: Default Route and Classless Routing
http://routingandswitching.blogspot.com/2004/10/default-route-and-classless-routing.html
Every step on the way. Default Route and Classless Routing. By default, if a router receives a packet destined for a subnet it does not recognize, the router discards the packet. However when classless routing is enabled, instead of discarding the packet, the router forwards the packet to the best supernet route. There are three ways to define gateway of last resort:. Ip route 0.0.0.0 0.0.0.0. More information can be found at:. Route Selection in Cisco Routers. Posted by - H - @ 11:46 AM.

CCIE Lab Quest: Switching
http://routingandswitching.blogspot.com/2004/10/switching.html
Every step on the way. Three VTP modes: server mode; client mode and transparent mode. Extended VALNs can only be added under the transparent mode. 8021Q by default does not tag the native VLAN. ISL doesn't have native VLAN, it tags all VLANs. Cisco switches use DTP to negotiate trunk mode and encapsulation mode. Two etherchannel negotiation protocols: Cisco's proprietary PAgP and industry standard LACP. Two switches will form etherchannel with the following modes:. No PAgP or LACP). 1 Select Root Bridge.

CCIE Lab Quest: OSPF
http://routingandswitching.blogspot.com/2004/10/ospf.html
Every step on the way. OSPF routers send out Hello packets every 10 seconds (30 seconds for NBMA and Point-to-Multipoint networks) to negotiate a two-way neighbor relationship (in order to become neighbors, they must agree on certain parameters such as Hello interval and network types). A neighbor is declared down if no Hello packet is received within the dead-interval (by default 4 x Hello-interval). 224005 is All OSPF routers. 224006 is All DRouters (DR and BDR). Elects DR and BDR. Creates a /32 host r...

CCIE Lab Quest: EIGRP
http://routingandswitching.blogspot.com/2004/10/eigrp.html
Every step on the way. EIGRP stub routing will suppress transit eigrp updates, it receives updates but will not passon to downstream neighbor. EIGRP allows you to summarize route on the interface level with command. Ip summary-address eigrp 100 144.1.0.0 255.255.0.0. It creates a static route for the summarized network pointing to the null0 interface. The default constant values are. EIGRP metric can also be manually changed using offset-list. Ip hello-timer eigrp 100 10. Ip hold-timer eigrp 100 75.
