Bridging 2 ISP VPN

[Julius Santos]

Good Day,

Ive got the device SG 500-28 which i configured it to layer 3. My question is how to configure the 2 ISP VPN to interconnect with each network.

ISP 1:

IP = 10.252.0.1/24

subnet= 255.255.255.0

GW = 10.252.0.1

ISP 2:

IP = 20.252.0.1/24

subnet= 255.255.255.0

GW = 20.252.0.1

* I want to ping the ISP 2 if my current ip used is ISP 1 IP or vice versa *

any one can help me out this problem coz i tried many times with all my knowledge but no luck to successfully configure.

Thanks in advance..

You need to explain a little more what you are trying to achieve.

Are you trying to use both VPN's at the same time, i.e load balancing?

Are you looking to use VPN 2 as a backup for VPN 1?

What sort of VPN are they?

Good Day sir,

My current connection with leased-line vpn is from ISP 1:

my HQ ip is start with 10.252.0.1/24 and 0.1 is the gateway router provided by isp then 10.252.1.2, 10.252.3.1 and so on are our remote branch. they're both interconnected that configured already by the ISP. all these ip addressing are interconnected with each other.

Now the 2nd ISP start with 20.252.0.1 which our headquarters IP and 0.1 is their router gateway then 20.252.2.1, 20.252.3.1 are also from our remote branch which the isp1 cant provide the services of the said area.

my question is, if i used the IP of ISP 1 which is 10.252.0.2, how I can establish a link through ISP 2? in which it is in a different subnet..

Thanks for you reply sir
