I have three routers. R1 on the left is running OSPF, R2 in the middle is running rip, and R3 on the right is running OSPF. R1 and R3 are connected to each other via a bridge group in R2 that does not have an IP address at all, just configured as transparent bridging. I can pass traffic (i.e. ping/telnet/tracert) between R1 and R3 through R2, however i am not receiving any OSPF updates. Essentially OSP does not redistribute through the bridge group in any way, shape, or form. Does anyone have a soultion for this? i can provide router configs if requested.
