Came across this formula in CCNP studies for determining number of adjacencies required when using BR and BDR in a full mesh environment. The formula is 2 x (n-1) where n = number of nodes. Taking a 4 node situation, the number of adjacencies woul...

Came across this statement:EIGRP automatically load balances across links of equal costs. Whether the traffic is sent on a per-destination or round-robin basis depends on the internal switching within the router.Could somebody let me know which fash...

Studying for CCNP. Came across the following definition for supernet as follows:SUPERNET----A summarization of class addresses given out by the internet community. For example, a group of Class C addresses 200.100.16.0 through 200.100.31.0 could b...

Studying for CCNP routing exam. Want to get this straight. Lets say a router loses an operational passive route and does not have a feasible successor in the topology table. It will then query its neighbors for a feasible successor. Will it also ...

If you have two t-1's coming into the 3640, could you not swing them over to each others interface and see if the problem follows the line or stays on the same interface?

IHL field is 4 bits long and indicates number of 32 bit words. With 4 bits you can count up to 15 decimal and therefore can have up to 15 32-bit words. If one byte is eight bits long, each 32-bit word has 4 bytes. With 15 total words you have a max...

Thanks for all the help. The one that I would go for is (n-2)x2+1 = 2n-3. That seems to make the most sense to me.

Thanks for taking the time to response. So the formula 2 (n-1) is bogus.

Shouldn't first network with with 10 hosts be 11.253.26.16/28. Typo, I bet.
