The maximum definable hop count is 255 but 224 hops is the true limit.

Subject: EIGRP Maximum-hop
Hi all, I have question about EIGRP maximum hops, based on
http://www.cisco.com/en/US/tech/tk365/technologies_white_paper09186a0080
094cb
7.shtml we can set up maximum 220 hops, based on some CCNP materials it
is
224. I test it on my router and 255 hops was OK.
Routing Protocol is "eigrp 100"
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Default networks flagged in outgoing updates
Default networks accepted from incoming updates
EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0
EIGRP maximum hopcount 100
EIGRP maximum metric variance 1
Redistributing: eigrp 100
EIGRP NSF-aware route hold timer is 240s
Automatic network summarization is in effect
Maximum path: 4
Routing for Networks:
Routing Information Sources:
Gateway Distance Last Update
Distance: internal 90 external 170
Then I have changed metric maximum-hops
Router(config)#router eigrp 100
Router(config-router)#metric maximum-hops 255
Router(config-router)#end
Router#sh ip protocols
