When sending an EIGRP update, does the packet contain topology table
information, or just the successors?
Also, how many routes are sent in a packet? One packet for each network
or more?

Thanks in advance.

Just next hops, which will be interpreted as feasible successors based on
the topology table. The topology table is formed from the information.

As many as will fit in the MTU. The update packet will contain as many TLV
(type-length-value) chunks as can fit on the medium.

Thanks, but EIGRP update can contain either ALL entries for all
destinations in topology table, or just the best routes after DUAL.
which once it passes to the neighbours?

Thanks, yaron.
