Hello
In Lab 12 I have an issue with R8 not getting any default route over EIGRP
from ASA. I dont know how to continue my troubleshooting. Whats next step?
This what I have found:
1)
ASA1 config looks ok. Redistributing ospf routes, but only 6.6.2.0 and
default:
router eigrp 89
no auto-summary
network 10.1.1.0 255.255.255.0
network 10.17.17.0 255.255.255.0
redistribute ospf 1 metric 1 1 1 1 1 route-map O2E
route-map O2E permit 10
match ip address O2E
access-list O2E standard permit host 0.0.0.0
access-list O2E standard permit 6.6.2.0 255.255.255.255
2)
ASA1 ospf database contains a 0.0.0.0 Type-5 from 192.1.49.31
3)
BUT! ASA1 routing table contains this default route:
D* 0.0.0.0 0.0.0.0 is a summary, 0:53:07, Null0
4)
R8 contains the 6.6.2.0-route which proves that redistribution works. But
there is no default route!
R8#sh ip route | beg resort
Gateway of last resort is not set
6.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
D EX 6.6.2.0/24 [170/2560002816] via 10.1.1.1, 00:46:06, FastEthernet0/1
C 6.6.99.8/32 is directly connected, Loopback0
10.0.0.0/24 is subnetted, 2 subnets
D 10.17.17.0 [90/28416] via 10.1.1.1, 00:53:36, FastEthernet0/1
C 10.1.1.0 is directly connected, FastEthernet0/1
5)
R9 (on DMZ) gets its summary default-route as expected.
R9#sh ip route | beg resort
Gateway of last resort is 10.17.17.10 to network 0.0.0.0
10.0.0.0/24 is subnetted, 1 subnets
C 10.17.17.0 is directly connected, FastEthernet0/1
D* 0.0.0.0/0 [90/28416] via 10.17.17.10, 00:44:25, FastEthernet0/1
That null0-route in ASA1 confuses me. Where does it come from? Can someone
point me into the right direction, not primary to find the solution, but
more to teach me how to think. what is next step of logic in troubleshooting
a situation like this?
Thanks!
