Hi,
Not sure if anyone else has seen this issue or not.
I have an RB3011 with a static IP provided by PPPoE. It's running 7.1RC2
I also have two CHRs in two seperate datacentres running 6.48.4 that each have an EoIP tunnel to the RB3011. These tunnels continued to work after the RB3011 was upgraded to 7.1RC2.
On the CHRs ether1 is WAN and ether2 is connected to a bridge called CoreNet. The EoIP interface is also connected to the CoreNet Bridge.
On the RB3011 ether6 is connected to a bridge also called CoreNet and again the EoIP interface is also added to this bridge.
After upgrading my test environment's CHR to 7.1RC2 the EoIP tunnels establish their connection successfully however devices on one bridge can now no longer see the other.
I've tried deleting the tunnels, Creating as simple tunnel without IPsec, manually configuring MTU on the tunnels, fragment, no fragment, Clamp MSS, no Clamp MSS and so on but with an 7.1RC2 to 7.1RC2 tunnel devices at each end just cannot see each other.
Reverting the CHR back to 6.48.4 results in the devices on each each end of the bridged tunnel being able to successfuly communicate again.
Not sure where to look next. Since the EoIP tunnels establish themselves correctly my suspicions are with the bridge configuration however the bridge configuration seem identical whether running 6.48.4 or 7.1RC2 and it's happening on two seperate CHRs.
