Hi Laz,
I manually assigned the IP address to PC 3 in VLAN 10
192.168.10.66 255.255.255.192, with a gateway of 192.168.10.65
Can you say if the configuration below is correct:
AREA 1 CONFIG
L3_SW1
int gig0/2
description TO R6
no switchport
ip address 192.168.100.26 255.255.255.252
int vlan 10
ip address 192.168.10.1 255.255.255.192
router ospf 1
network 192.168.100.26 0.0.0.0 area 1
network 192.168.10.0 0.0.0.63 area 1
AREA 2 CONFIG
L3-SW2
int gig0/2
description TO R4
no switchport
ip address 192.168.100.34 255.255.255.252
int vlan 10
ip address 192.168.10.65 255.255.255.192
router ospf 1
network 192.168.100.34 0.0.0.0 area 2
network 192.168.10.64 .0.0.63 area 2
PC 1 connected to L3-SW1 in Area 1 can ping to all the interfaces on all the routers.
When I use this command on L3-SW2 : network 192.168.10.0 0.0.0.255 area 2 , the hosts in Area 2 can ping to all.
When I use this command: network 192.168.10.64 0.0.0.63 area 2
PC 3 connected to L3-SW2 in Area 2 can ping to both interfaces on Router 4, and can
also ping to the interface on Router 3 connecting to Router 4, but PC 3 cannot
ping to the other interface on Router 3 connecting to router 1.
Also router 4 in Area 2 can ping PC1 in Area 1
I am not sure what is miconfigured or what is not configured, or how to troubleshoot this.
It seems like something has to be fixed on router 3
