Hi Joseph,
I tried that one as well but still doesn't work, actually if I do it without
access it looks like none of the EIGRP external router are filtered but the
internal EIGRP are filtered:
R2-LAB#sh run | s eigrp
router eigrp 236
network 192.168.252.0
network 192.168.254.0
distance 255 192.168.254.1 0.0.0.0
no auto-summary
R2-LAB#
R2-LAB#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static
route
o - ODR, P - periodic downloaded static route
Gateway of last resort is 192.168.254.1 to network 0.0.0.0
10.0.0.0/32 is subnetted, 1 subnets
D EX 10.1.6.5 [170/2565120] via 192.168.254.1, 00:04:39, Vlan1
C 192.168.254.0/24 is directly connected, Vlan1
C 192.168.252.0/24 is directly connected, Loopback0
D*EX 0.0.0.0/0 [170/2565120] via 192.168.254.1, 00:04:39, Vlan1
R2-LAB#
