I deployed Cisc Optimized Edge Routing (OER) on a router connecting to two different ISPs using a Switch. One DSL ISP and one VSat ISP. The DSL Modem is connected to the Switch and configured to be in VLAN 168, while the VSat Modem is connected to thesame Switch and configured to be in VLAN 10. The F0/0 of the Router on which Cisco OER is configured is connected to thesame Switch and configured as Trunk connection, 2 Sub-interfaces are created and trunking mode configured as IEEE 802.1Q. The port on the Switch where the Router is connected is also configured as a Trunk with IEEE 802.1Q. The F0/1 of the Router is then connected to a Switch in my LAN.
Additional Features configured on the Router include, NAT, IOS Firewall on the 2 Sub-interfaces connected to the Switch, and then ACL applied to the 2 Sub-interfaces as well.
I then configured OER on the Router, it is both Master and Border router, the 2 Sub-interfaces (created from Router F0/0 physical interface) are configured as OER External interfaces while the F0/1 Physical interfaces is configured as OER Internal interface. To the best of my knowledge everything is configured well but when the primary Link, which is the DSL, is disconnected by removing the cable connecting the DSL Modem and the Switch, Cisco OER does not failover successfully to the VSat ISP as expected. Sometimes I see OER Static Routes in the Routing Table but traffic is not sent successfully through the VSat Link. Can anyone take a look at the attached configuration and advice as soon as possible.
