STATIC ROUTING

[Himanshu_Dwivedi]

Hello 

Above is the Topology in which there is 1 ISP with Two Sites. One Site is Connected with WAN IP(10.0.0.0/24) with ISP and other Site is (20.0.0.0/24). Site 1 is having Loopback(1.1.1.1) and Site 2 is using (2.2.2.2). 

Routing Config :

1. Made Site 2 WAN IP reachable from Site 1 and Vice versa with a static route.

2. Configure Static Route for Loopback at both the end.

Issue : Both the sites loopback are unreachable with each other but when I check in Routing Table routes are showing

Working on : while configure static route on ISP ROuter  pointing towards both site.

But I dont want to add  anyting on ISP Router just only want to play with with Sites Router.

ISP router you need static route back to respected sites (since you are not running any routing protocol).

test below and let us know how it goes.

ISP router :

ip route 1.1.1.1 255.255.255.255 10.0.0.2

ip route 2.2.2.2 255.255.255.255 20.0.0.2

Site 1

no ip route 2.2.2.2 255.255.255.255 20.0.0.2

no ip route 20.0.0.2 255.255.255.255 10.0.0.1

ip route 2.2.2.2 255.255.255.255 10.0.0.1

ip route 20.0.0.0 255.255.255.0 10.0.0.1

Site 2

no ip route 1.1.1.1 255.255.255.255 10.0.0.2

no ip route 10.0.0.2 255.255.255.255 20.0.0.1

ip route 1.1.1.1 255.255.255.255 20.0.0.1

ip route 10.0.0.0 255.255.255.0 20.0.0.1

Sir,

This thing I already tested and working but As already mentioned that I dont want to anyting on ISP router other that IP COnfiguration and also don't have access to ISP router so I only want to do it between the sites. Any possibility in this type of scenario.

May be i miss that bit, if you do not have control over ISP, ISP do not have any routing place ? (its hard to do that task)

but if you able to reach other side router from site 1 to site 2  and stie 2 to site 1 example  :

10.0.0.2 can reach 20.0.0.2 - and 20.0.0.2 can reach 10.0.0.2 you can do VPN between Site 1 and site 2.

is this make sense ?

[Himanshu_Dwivedi]

Yes I have made both the Routers WAN IP reachable with Each other. Just only want to make LAN reachable.

You are saying to get SITE 2 SITE IPSEC VPN Configured????

[balaji.bandi · Accepted solution]

IPSEC or GRE to establish direct connection between site.
