Hi Nigel,
R2 is getting the default-route from R1. I configured on R1
"area 1 nssa default-information-originate" on R1.
R2 see the default-route from R1 and the "Gateway of
last resort will set proper. Look:
R2#sh ip route
.
.
Gateway of last resort is 192.168.0.1 to network 0.0.0.0
.
.
11.0.0.0/32 is subnetted, 1 subnets
O IA 11.11.11.11 [110/65] via 192.168.0.1, 00:19:10, Serial1
C 192.168.0.0/24 is directly connected, Serial1
O*N2 0.0.0.0/0 [110/1] via 192.168.0.1, 00:14:28, Serial1
On R2 I redistribute the Network 192.168.0.0/24 and 11.11.11.0/24
into the RIP domain. That's working fine and I see the OSPF routes
inside the RIP domain. Look:
R3#sh ip route
.
.
Gateway of last resort is not set
.
.
R 11.0.0.0/8 [120/10] via 10.1.3.1, 00:00:18, Ethernet0
R 192.168.0.0/24 [120/1] via 10.1.3.1, 00:00:18, Ethernet0
The problem is that the RIP don't pick the default-route and propagate
it within RIP. I tried the command "default-information originate" on R2
under the rip process. But it doen't work.
Any other idea's ? I will also read Doyle. Maybe he has an answer for me.
