ROUTE Notes - More IGP Redistribution

As always, feel free to correct. Study Notes * When a router redistributes from one routing protocol to another, where does the router get the list of routes to redistribute? From the routing table. Only IGP A’s routes (not topology or successors) are redistributed into IGP B’s domain. * What

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.
