I set the default gateway already to another device and when eth0 gets plugged in the traffic goes through it instead.<br />Reading about vrf management (<a href="https://docs.cumulusnetworks.com/display/DOCS/Management+VRF#ManagementVRF-ViewingtheRoutingTables" rel="nofollow" title="Link: https://docs.cumulusnetworks.com/display/DOCS/Management+VRF#ManagementVRF-ViewingtheRoutingTables">https://docs.cumulusnetworks.com/display/DOCS/Management+VRF#ManagementVRF-ViewingtheRoutingTables</a>) sounds like it could solve this. Is it true to say that enabling vrf mgmt on eth0 would make it use a separate routing table?<br />Would this then keep the front panel traffic from traversing it as a default gateway and use the original default gw configured?<br /><br />Kind regards,<br />penny01 question 2 2 1 comment http://m.getsatisfaction.com/topics/7601784 7601784 Does Cumulus Linux support SPB (802.1aq)?
