i need to access all routers from my local desktop

[R Manjunatha]

Hi,

I am running BGP, OSPF, and EIGRP routing protocol in EVE-NG and I need to access all my routers from my local desktop

what could be the route configuration? I can be able to ping from my desktop R120 and further I can't any other routes.

I have attached my topology.

I am not finding any route from R60 and R63 and also, it's not pining.

clarification - show IP route 8.8.8.8 - This is the DNS server IP and how is this route will install in the routers R60 and R63?

Hi @R Manjunatha ,

> clarification - show IP route 8.8.8.8 - This is the DNS server IP and how is this route will install in the routers R60 and R63?

If you want to ping the DNS from R60 and R63, they need to have a route to it. The route to 8.8.8.8 will be via the default route propagated via eigrp and then redistributed into bgp on R61.

Can you check that the default route propagated to R61? I suspect that the default route does not propagate to AS65002 because you are missing the following command under "router bgp 65002" on R61.

router bgp 65002

default-information originate

This will allow the default route redistribution from eigrp to bgp. You should then see the default route propagate to R60 and R63.

Regards,

[R Manjunatha]

Hi,

Thank you for the clarification.

I configured the "default-information originate" and I am able to ping DNS from R63 and similarly I can't ping from R60 BGP routers AS65002. I can reach from R61

Hi @R Manjunatha ,

I am glad to see that it works for some routers. The fact that it doesn't work from R60 is probably due to the fact that the only prefixes you advertise from R60 are in the 192.160/16 range. You need to add this range to the access-list you use for the NAT on R120.

Regards,

[R Manjunatha]

Hi

I have given a 192. /8 range to access-list in R120
