I recently installed a Riverbed WAN accelerator connected to the second interface on a 7206 router. The router has an ACL which only allows certain traffic to be forwarded to the riverbed. I also have a second riverbed and router 3745 used for redundancy and path diversity. There is HSRP running between both routers (7204/3745) and all 4 devices are on a closed Vlan which is not routed from the core routers, however this core router is a sup720 running on a 6509 and I am using the switch ports to connect to these devices. The primary interface on the 7204 and 3745 also connects to the same core routers/switches, but on speretate vlans. The traffic flow should be from the core router to the 7204/3645 router to Riverbed back to 7204/3745 and then out onto the WAN. What I am seeing is ALL traffic is going to the Riverbeds completely bypassing the ACL on the 7204/3745's. There is no directly connected route visible to the Riverbed network from the core router and the VLAN is not defined on the Core router however the VLAN is defined on the switch.
I was hoping someone had seen this before, and offer any solution? The 6509 is running CatOS.
