Configure Secondary ILL ISP

FarhanKoujalgi — Mon, 20 Sep 2021 17:10:16 GMT

Hey, Guys, one of my customers wants to configure a secondary ISP he change his ISP and Now want to configure the NEW

ILL(Internet Leased Line) ISP. to the same interface. I configure the Virtual route, NAT and added new ISP Ip but was not able to UP that Link after I added path monitoring I took ssh and ping source ISP IP to host 8.8.8.8 getting ping but the traffic goes through the primary ISP ping source ISP IP to host the ISP gateway getting ping but not able to see logs as customer want to go the subnet mask is /22 and the ISP IP and gateway are in the different subnet

, for example, ISP IP 44.33.186.33

ISP gateway: 44.33.184.1.

is that something to do with Gateway in ILL configuration?

@FarhanKoujalgi,

How are you trying to route the traffic through the new ISP? Path monitoring directly on the device doesn't hit PBF if that's how your attempting to route this traffic it isn't going to work. In addition, when you say you can't get the interface show its online that would be a layer1 or configuration issue and should be solved before you attempt to fix anything else.

for example, ISP IP 44.33.186.33

ISP gateway: 44.33.184.1.

As per example, I route the ISP in the virtual router by destination 0.0.0.0 and the next hop is 44.33.184.1 which is the isp gateway.
