remember this topology replaces a serial cable with an ethernet cable between r1 and r3... my numbers don't macth with the output from the manual... a minor disappointment, but still a disappointment...
according to the lab the composite metric for both links from r3 should be 41024000/40512000...
here's what i got:
r3#sh ip eigrp topo 10.1.102.0/29
IP-EIGRP (AS 100): Topology entry for 10.1.102.0/29

r3#
the delay is nearly half that of the serial cable... so let's fix it... let's make the ethernet cable a serial cable...
r3(config)#int f0/0
r3(config-if)#delay ?
<1-16777215> Throughput delay (tens of microseconds)
r3(config-if)#delay 2000
r3(config-if)#end
r3(config-if)#delay ?
<1-16777215> Throughput delay (tens of microseconds)
r3(config-if)#delay 2000
r3(config-if)#end

note the delay is in tens of microseconds with the interface delay command... i arrived at 2000 because delay is in tens of microseconds, and it was already at 20100... 2000 times 10 is 20000 microseconds plus it's current delay... in other words, i guessed correctly, i can add and multiply and i nailed the sucker...
my metric output for the topology is exactly that of the lab manual...
it's not defining relativity but it's still kinda cool...
