how to adjust interface metric in ospf to define desired route ?

venkat_g — Wed, 22 Jan 2020 07:34:34 GMT

I have to two virtual routers

VR_1 - e1/1 - is connected to wan 1, e1/3 - is connected to internal network, e1/4 is connected to a switch so, VR_1 has e1/1,1/3,1/4 and I want the primary ospf route to be from e1/4. what changes should I make to do set all routes pass through e1/4.

VR_2 - e1/2 - is connected to wan 2.

currently all interfaces are in ospf network.

You can do this under the VR. VR > OSPF

Hello,

To supplement what @ArminGradscevic stated:

Networking Tab -> Virtual Routers-> the virtual router you are using->OSPF->Area->Interface tab

Then select the interface you want to make a heavier weight and set the metric. I usually keep my default one as the default of 10. Then I use intervals of 5000 for metrics since that usually is enough to override what OSPF selects. The higher the number, the less desirable OSPF will make that route.

Hope that helps.
