ROUTE Notes - IGP Redistribution

As always, feel free to correct. Study Questions * When you redistribute OSPF into EIGRP, what are you really redistributing? Routes knows via OSPF Networks of OSPF-enabled interfaces * What’s the default cost of an EIGRP route redistributed into OSPF? 20 * What’s the default metric of an OSPF route redistributed

ROUTE Notes - OSPF Virtual Links and Frame Relay Stuff

Feel free to correct. I feel like I’m missing a big piece here, so please fill in a gap if you see one. Thanks. 🙂 Study Questions * How many area 0s (zero) can you have in an OSPF implementation Just one. * If my company merges with another company, and we’

ROUTE Notes - OSPF Filtering and Summarization

Feel free to correct all this stuff. Additions are also welcome. Study Questions * How do I keep an area route from reaching a router in that area? You don’t. That defeats the whole purpose of having the topology database on every router. If you filtered one route from a

ROUTE Notes - OSPF Topology Stuff

Feel free to correct. Study Questions * The obvious first question involves the common LSA types and their function. Can you list them? Type-1 – Router – Lists each router their connected IP addresses Type-2 – Network – Lists all the transit, or multiaccess, networks Type-3 – Net Summary – Defines a host route for interarea routes;

ROUTE Notes - OSPF Neighbor Relationships

Feel free to correct. Study Questions * What are the definitions of the hello and dead intervals? The hello intervals is how often a router sends hello messages. The dead interval is how long to wait before considering a neighbor dead from lack of hello messages; this is 4x the hello

ROUTE Notes - Controlling Routes in EIGRP

Corrections welcome. Study Questions * Why would you ever want to summarize routes? Summarizing routes minimizes the routes advertised to the network. For example, instead of advertising 192.168.0.0/24, 192.168.1.0/24…192.168.n.0/24, a router can advertise a single route to 192.

ROUTE Notes - EIGRP Topology Stuff

Study Questions * How do you keep EIGRP from killing your WAN? You can use the ip bandwidth-percent eigrp AS X command to limit the amount of bandwidth that EIGRP uses to update neighbors. * How does EIGRP calculate how much bandwidth it can use for each frame relay PVC? By default,
