we have a cisco2621,ios is 12.2 or 12.0.7t,configuration is as follows:
interface FastEthernet0/0
ip address 82.0.0.1 255.255.255.0
no ip directed-broadcast
duplex auto
no sh
speed auto
£¡
router eigrp 100
network 82.0.0.0
no auto-summary
!
ip route 1.0.0.0 255.0.0.0 82.0.1.2
when we shut down fa0/0,static route disappear.after fa0/0 goes up, static route appear.That's right.
Then,we add such configuration:
int f0/0
ip summary-address eigrp 100 82.0.0.0 255.0.0.0
and shut down fa 0/0 again,the routing table seems strange:
S 1.0.0.0/8 [1/0] via 82.0.1.2
82.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
D 82.0.0.0/8 is a summary, 00:00:51, Null0
C 82.0.0.0/24 is directly connected, FastEthernet0/0
static route exist when there's eigrp summary route.
Is it the ios problem?for I tried in the 12.0.5T,static route will disappear after fa 0/0 shutdown.
thanks.
