Finished EIGRP Lab

EIGRP configurations notes

#router eigrp 10 (AS number)
#no autosummary
#network netID wildcast

Tune the update interval,hold time
Under interface config mode
#ip hello-interval eigrp 10 30
#ip hold-time eigrp 10 120

Tune timer
Under router eigrp mode
#timers avtive-time 60 or disabled

Change the AD for internal/external
Under router mode
#distance eigrp 90 110 (90-internal, 110-exterlnal, default 170)

summarization
Under interface config mode
#ip summary-address eigrp 10 192.168.0.0 255.255.252.0

Verify by #show ip route
EIGRP will inject a discard route to Null0
D 192.168.0.0/22 is a summary, ....., Null0

Advertise a summary route plus specific routes
use leak-map under interface config mode
#ip summary-address egirp 10 192.168.0.0 255.225.252.0 leak-map ROUTE-map

If the routemap doesnt exit, only summary routes will adv
If the routemap exist, but the route map refer to ACL that doents exist, the summary routes + all the specific routes will adv
If the routemap exist, but the route map refer to the ACL, the summary route + routs in the ACL will adv

Load balancing for unequal cost
Use variance under router mode

Authentication
use the same config as RIPv2 by using Key chain.
But only support MD5. dont support cleartext.
