                  How to Configure SIG Tunnel using vManage for SDWAN Before we configure from vManage , follow the steps : Step 1 : Login to Cisco Umbrella Portal (https://login.umbrella.com/) Step 2 : Click on Admin --> API Keys -- > Click on Umbrella Management Note : If Keys are not generated then generate it & copy the key & secret (we need to use this info in vManage SIG feature template) Org ID is written at the URL , Example : https://dashboard.umbrella.com/o/ ORG_ID #/admin/apikeys Step 3 : Login to vManage & create SIG credential feature template & enter Umbrella Key, Secret & ORG ID copied from Umbrella Portal Step 4 : Once SIG credential feature template created, then create SIG feature template add the details like Ipsec tunnel number , Source Interface (VPN 0 transport interface) & IKE parameters to build IPSEC tunnel (SIG) with Cisco Umbrella And if you have added 2  Tunnels then in high availability section of SIG feature template one you a
