Can’t ping router0

[Martin L · Accepted solution]

you can attach PT file here ; just zip it and attach,

you do not have any protocols enable and running; you started RIP but is missing configs.  For example all layer 3 sw should have  

router rip

version 2

network 192.168.10.0

network 192.168.20.0 

network 192.168.30.0

network 192.168.99.0

Or router OSPF 

network 192.168.10.0 0.0.255.255 area 0

Do I need to do that to the router as well ?

[josephmcmahon536428721]

I applied ospf on the layer 3 switches but it still doesn’t ping the the router from a vlan pc ?

[Martin L]

Yes, I think RIP is no longer on CCNA exam but you can practice in PT. then move to EIGRP before finishing on OSPF.
If Route redistributing is on exam, you can practice redistribution OSPF to EIGRP and vice versa. but start with single protocol first (only ospf or only eigrp).

I put ospf on all the layer 3 switches and the router but it still won’t ping the router ?

One more thing; all L3 switches have same IPs for vlans 10,20,30. it should not! Change IPs; Lets say Dist Sw 1 stays; Dist 2 and Dist 3 must have different IPs. they can have same vlan 10, 20,30,99 but 192.168.10.x where x is different IP then other switch. then change default gateway for those connecting PCs to point to respective L3 sw IP.
there cannot be duplicate IP on the same network or in the same organization.

Will I need to add multiple dhcp severs then ?

[josephmcmahon536428721]

if i change for example the distribution switch 1 vlan 10 ip to 192.168.10.1

and distribution switch 2 vlan 10 ip to 192.168.10.2 what ip do i put for the vlan 10 on the core switch

[Martin L]

Another /30 range of subnets should connect Distribution 1,2,3 to Core Sw. just like Core Sw to router link.  you can use any Private ranges /30s for those point-to-point links.
