Marco,
Seems to work for "normal" eigrp default-network routes (other than
0.0.0.0/0) The access list after "default-information in" qualifies the
route carrying the default-route flag. Also, I've read 0.0.0.0/0 is not
understood by EIGRP as a valid route.
#Does not allow 133.0.0.0 to be the default network.
ip acce s kill133
deny 133.0.0.0
permit any
router eigrp 5
default-information in kill133
#The following filters 0.0.0.0 succesfully.
router eigrp 5
distribute-list nodefault in TokenRing0
!
ip access-list standard nodefault
deny 0.0.0.0
permit any
AP

Subject: Eigrp - default-information
Hi all,
There is something the I really don't understand about Eigrp and
default-information command, I am trying to block the default with this
command (I have tried other cases but ... failed)
Quite easy configuration:
router eigrp 2
network 172.16.100.0 0.0.0.255
network 192.168.1.0
default-information in 1
no auto-summary
access-list 1 deny 0.0.0.0 log
If I look at the show ip protocol it seems ok
sh ip protocols
Routing Protocol is "eigrp 2"
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, if matching access list 1
Also the show access-list shows matches
#sh access-lists
Standard IP access list 1
deny 0.0.0.0 log (8 matches)
But if I look at the routing table I find the default and the other external
#sh ip route eigrp
172.16.0.0/16 is variably subnetted, 5 subnets, 5 masks
D EX 172.16.2.0/24 [170/21441536] via 172.16.100.2, 00:10:55, Serial1/0:1
D 192.168.2.0/24 [90/20640000] via 172.16.100.2, 00:58:24, Serial1/0:1
D EX 192.168.33.0/24 [170/21441536] via 172.16.100.2, 00:10:55, Serial1/0:1
D*EX 0.0.0.0/0 [170/21441536] via 172.16.100.2, 00:09:10, Serial1/0:1
Do you have any idea what it wrong, I searched a lot for default-information
but it is a quite hard search because it is spitted in default and
information ... it matches everything.
Thank you in advance
