Here's a (albeit minor) quirk:
R6(config-if)#do sh run int fa0/0
!
interface FastEthernet0/0
ip address 172.16.0.2 255.255.255.0
ip summary-address eigrp 100 0.0.0.0 0.0.0.0 25
end
** note AD for summary set to 25 **
R6(config-if)#do sh ip ro 0.0.0.0 | i distance
Known via "eigrp 100", distance 25, metric 28160, candidate default
path, type internal
R6(config-if)#ip summary-address eigrp 100 0.0.0.0 0.0.0.0 50
** AD for same (existing) summary set to 50 **
R6(config-if)#do sh run int fa0/0
!
interface FastEthernet0/0
ip address 172.16.0.2 255.255.255.0
ip summary-address eigrp 100 0.0.0.0 0.0.0.0 50
end
R6(config-if)#do sh ip ro 0.0.0.0 | i distance
Known via "eigrp 100", distance 25, metric 28160, candidate default
path, type internal
** new AD of 50 not automagically applied to existing route **
R6(config-if)#do clear ip ro 0.0.0.0
R6(config-if)#do sh ip ro 0.0.0.0 | i distance
Known via "eigrp 100", distance 50, metric 28160, candidate default
path, type internal
R6(config-if)#
The AD is only updated if you clear the route from the routing table,
or completely remove/re-add the summary. Not a big deal, but worth
putting in the "not really that important but could hurt late on lab
day" category.
cheers,
Dale
