Arthur,
For point 1 use show run. For point 2, there is a very little documented,
but interesting aspect to the EIGRP holdtime. When a router forms an
adjacency with another router, it informs the router of its hello time. The
router receiving this info then sets the expected holdtime for that
neighbour to three times the hello time that it was advised. Thus you can
indeed have two routers as neighbours with differing hello timers. This is
of course different than the behaviour experienced with OSPF.

Subject: questions about EIGRP
I don't know if someone has asked the following questions before.
1. I have configured a sub-interface to different hello interval such as 20
and hold time as 60 in EIGRP. Which command will show the hello interval
and hold time values? In OSPF, the command "show ip ospf int" will do it.
But I didn't find such command in EIGRP.
2. I have configured point to point routers in EIGRP. After I change the
hello interval and hold time value on just one router, which means both
routers should use different hello-interval and hold-time values, then why
both still showing neighbors when I do "show ip eigrp nei"? If I remember
correct, in OSPF if hello interval doesn't match, then both routers won't
form adjacency. Correct me if I am wrong.
